MVS 无线电设备的 Power Amplifier Board（A4）说明书
DESCRIPTIONThe Power Amplifier Board (A4) used in the MVS radio is housed in a cavity running parallel to the side of the radio main casting assembly. Refer to the combination manual for a complete mechanical layout of the radio.The PA Board amplifies the driver output from the RF Board (approximately 10 watts) to a level of approximately 25-30 watts, over the frequency range of 403-512 MHz.There are no tuning adjustments on the board.The board consists of a single stage RF power ampli-fier. Also included on the board is a diode for reverse power protection, as well as two multi-pin connectors used to dis-trib-ute non amplifier related signals in the radio. Two small jacks are used to apply drive to, and take RF output from the amplifier. The 403-512 MHz range of UHF frequencies is covered by three groups of PA Boards:19C851617 G1: 403-440 MHz 19C851617 G2: 440-470 MHz 19C851617 G3: 470-512 MHzCIRCUIT ANALYSISThe driver output from the RF Board (10 watts, 50 ohms impedance) is matched to the base of Q151 by CI51, C152,C153, C154, L151, and L154. Inductor L152 provides a bias return for class "C" operation. A network consisting of L153 and RI51 enhances stability.Once the drive is amplified to approximately 30 watts by Q151, it is matched back up to 50 ohms by C155, Cl56,C158, L156, and L157. C159 is a DC blocking capacitor,which keeps DC voltage from appearing at the amplifier output.A+ is supplied to the collector of Q151 through a net-work consisting of L155, L158, RI 52, C157, C161, and C162. In addition to enhancing stability, these components also prevent RF from getting onto the A+ line.The amplifier’s output is fed back to the radio’s RF Board where it passes through the antenna switch, low pass filter, and directional coupler before being applied to the an-tenna connector.Diode D151 provides reverse polarity protection. If power is accidentally reversed, this diode will conduct,causing the power cable’s A+ fuse to blow, thereby remov-ing power from the radio and preventing serious damage. A+ is applied through 6 pin connect J903 by feedthrough capacitor assembly Z903. Other non-amplifier related signals are routed through the PA Board for distribu-tion to other boards in the radio. These include A+, switchedLBI-31934CMAINTENANCE MANUAL POWER AMPLIFIER BOARD 19C851617G1 (403-440 MHz)19C851617G2 (440-470 MHz)19C851617G3 (470-512 MHZ)FOR MVSA+, Relay, and volume/squelch HI. A wiring harness plugs into J151 for this purpose.SERVICE NOTESThis amplifier can be easily checked without removing it from the radio. RF input (at J153) and output (at J152) impedances are 50 ohms.Remove all power from the radio when servicing the PA Board. The radio’s power switch does not remove A+ power from the board.There are 9 chip mica capacitors on this PA Board. If any are removed, replace them with a new part since they are easily damaged. Apply them in the exact positions shown in the outline diagram. Failure to do this will have an adverse effect on amplifier gain, bandwidth, and efficiency. PA TRANSISTOR REPLACEMENT1.Remove the two retaining screws securing PA tran-sistor Q151 to the chassis assembly.2.Unsolder the six leads of the transistor, and removeit from the printed board. Be careful not to dam-age the PWB, or capacitors C153, C154, andC156.3.Remove all excess solder from the board nearQ151, and clean the board to allow the new transis-tor to be positioned properly. Refer to Figure 1 andtrim the new transistor leads (if required) to thelead lengths of the removed transistor.4. Apply silicon grease to back of the replace-menttransistor and place the transistor in themounting cut out. Make sure that the base and col-lector leads are not reversed.5.Replace the transistor mounting screws using amoderate torque of 0.5 Newton meter (4.5 inch-pounds).6. Solder the 6 transistor leads to the printed board.Agaln, be careful not to damage C153, C154, C155 and C156.7.Remove any flux left on the board.Copyright© March 1988, Ericsson GE Mobile Communications, Inc.FIG 1 - PA TRANSISTOR LEAD IDENTIFICATIONPrinted in U.S.A.LBI-31934LBI-31934(19C851617, Rev. 1)(19A705304 Sh. 1, Rev. 0)POWER AMPLIFIER BOARD19C851617G1-G3LBI-31934POWER AMPLIFIER BOARD 19C851617G1-G3(19C851618, RE V. 2)PRODUCTION CHANGESChanges in the equipment to improve performance or to simplify circuits are identified by a "Revision Letter", which is stamped after the model number of the unit.

Please recharge or insert a newrecharged battery. The microphone will beshut down automatically if the battery keepslow status.OperatingInstructions75%50%(green indicator)25%(red indicator) 100%The patented color rear cap serves two purposes; it provides easy channel identification and protects the on/off switch. It is designed to allow the on/off switch to either be exposed or concealed asdesired. You can avoid unintended switching off of the microphone by rotating the color rear cap 180 degrees to fix the on/off switch. The cap can be removed by gripping it firmly and pulling; be sure to push it firmly into place when replacing it on the microphone.Note: During microphone usage, the color rear cap must be installed.1.Performer should avoid holding the microphoneover or near the antenna section as this will deteriorate transmission efficiency. Severedeterioration if performer directly covers up the antenna section with both hands. 2.Many performers tend to hold the microphoneby the top grille. Unfortunately, this position seriously degrades both the sound quality and directionality of a microphone. Even the most expensive microphones will have its original sound quality compromised by this method. Grabbing a microphone by the grille will isolate the capsule's acoustic resonance circuit orchange the capsule resonator's frequency. This results in an inferior performance in both frequency response and the separation of directionality. In addition, a palm's sound-focusing effect will tend to strengthenresonances in certain frequencies and can cause unwanted echo.3. A proper technique is required for usingdirectional microphones because the distance between the microphone and your mouth has a significant impact on sensitivity andperformance. There is an inverse relationship between microphone sensitivity and the distance from the mouth to the microphone.Rear Cap has an On/Off Switch ProtectionGeneral Tips for Improving SystemPerformancePress both sides and pull out to remove the rear capTurn the rear cap 180 degree and insert backThe ON/OFF switch is immovableAF Button: Light stands for audio signal. Press it and the light goes out.Audio Input Connector: TA4F mini 4-pin connector accepts any MIPRO lavalier , instrument and headset microphones andcables. (See 5 ways of connection on AF InputConnections)Bodypack Controls and IndicatorsConsequently, performers with a ''weaker'' sound level cannot expect to hold the microphone too far away from their mouth and compensate by turning up the amplifier volume to increase the sound level as this can easily cause echo or feedback. In contrast, performers with a ''louder'' sound level should not hold themicrophone too close as this can easily result in distortion by causing the amplifier system to be overloaded.4.Furthermore, a large-diaphragm directionalmicrophone has a very distinct proximity effect. When the microphone is close to the mouth, the bass response is strengthened as the distance gets closer . Therefore, if a performer's sound is insufficient in bass, they can hold themicrophone closer and use the proximity effect to help compensate for the lower bass level.Conversely, if a performer's voice is too heavy in the bass register , increasing the distancebetween the microphone and their mouth will decrease the proximity effect and reduce the bass response, thus making their voice become clearer and brighter .5.It is recommended to keep the grille and spongewindscreen clean to avoid any substanceblocking the proximity effect of the microphone.Capsule ConnectorAudio Input Operating Instructions1.Insert the lavalier , headset microphone orinstrument cable into the audio input connector before power ON the transmitter . 2.Tighten the connector screw clockwise directionas shown in (Figure 2) for a secured fit.Antenna: Flexible 1/ 4 wave transmitting antenna.Transmitter Housing: Holds PCB board and wires.Battery Level Panel: Display battery status.ACT IR Port: Align and syncs the transmitter and receiver frequency automatically.Power Button: Press and hold 2 seconds to power ON or OFF .Battery Circuitry Protection Reset Button Battery Compartment: Accommodates one 18500 rechargeable battery.Battery Cover: Hinged cover opens to provide access to one 18500 rechargeable battery.External Mute Connector: When an external mute switch cable, MJ-70 (optional) is connected , user can manually mute and un-mute the audio temporary.Belt Clip: Detachable and reversible design allows the transmitter to be worn on a belt, waistband, or guitar strap (.Battery Charging Contact: Align contacts during charging.(a)Metal objects contact is forbidden.(b)It is forbidden to contact metal objects.Figure 1)3.AF Button Setupa.Press AF Button to enter mute mode, andthe indicator doesn't light.b.Press AF Button again to un-mute, and theindicator lights.4.External Mute Connectora.External mute connector is a 3.5mm jack.When an external mute switch cable, MJ-70 (optional) is connected, user can manually mute and un-mute the audio temporary.5.MJ-70 External Mute Switch (Optional)3.5mm jack.External mute switch on/off button.NOTE:Plug it into the device before to power onthe bodypack transmitter.Operating Instructions1.Power On/Offa.Power On: Press the Power button to powerON.

Below are some simply steps to get you started in working with the unit. Further in this guide we will briefly discuss what each operation does.Step 1: Start by plugging the unit in to the PoE injector to begin charging the unit. You can use the unit while it is being charged. Connect the PoE injector with an Ethernet cable to the RJ 45 port labeled ‘Charge’ (it isgreen in color).Use the small grey button on the side of the unit to turn it on. A prompt should show our logo and quicklyafter move to displaying the main interface of the unitWe recommend you go to the ‘settings’ menu first to setup the ge neral attributes of the tester.Use the arrow keys to highlight ‘settings’and use the ‘right’ arrow key to jump in.Step 2: When at the main interface, use the directional arrows on the unit to move around. The yellow highlight is where you are currently positioned. Use the ‘right’ arrow to go in to the operation or wait a fewseconds and it will access it automatically. If you flip open the door on the front, it reveals a completekeyboard for various operations you will find throughout the unit.Here you can find general settings for the unit. We briefly describe the settings below.Auto Power Off– Allows the unit to automatically power off if not in operation. Saves batteryKeypad Tone– This will enable or disable the key press soundsLanguage – Default is EnglishBacklight– Varies the backlight contrast of the device from darker to brighterSystem Time / Date– Set your date / time for the unitSystem Upgrade– Notes the current version of the unit. Do not use this function unless instructed toStart USB Storage– Use this function to plug the unit in to a USB port on your PC to download captured video and snapshots. Once connected to your PC, tap the right arrow on this function. On the PC side, the unit should show as a device that you can access through disk management to extract files fromSerial Number– Current serial of the unit. Use this as a reference when calling in fro supportMain OperationsThis section will run through the basics of using the different operations of the tester. Resort to utilizing the manual for complete walkthrough of the operations.Step 1: Onvif Test: Use this function to test Onvif enabled cameras to assure you are getting a proper video stream. You also can test control of the camera once it is detected.∙Start with connecting a camera or connecting the ITM9000 to an active network device so to find the desired camera to test. You can use either of the RJ45 ports to perform this. Use the‘SET’ button to change the IP address on the ITM9000 so to access cameras on a differentsubnet. Use the ‘FOCUS’ or ‘IRIS’ keys to set its own DHCP server or search t he network for anavailable DHCP server.Note: The ITM9000 does support PoE. If the camera is PoE enabled, you shouldn’t have to power itexternally.∙Use the ‘right’ arrow to move to the next step. You should see your IP camera listed if setup correctly. Note if connecting to a network switch with various IP cameras, it will list allapproved Onvif cameras. Use the arrows to choose the desired camera. Use the ‘right’ arrow togo to the next step.∙Finally you will be at the location where you can control the camera to test various operations.You can also take a snapshot or record video from the camera to verify it working.Note: Onvif versions do progress. For future Onvif releases, always consult support to assure you have the latest firmwareStep 2: Analog Camera Test: Use this function to test analog and HD-AVS camera video streams. It also allows you to control the camera’s OSD (Onscreen Display) and PTZ movement if capable.∙Start by connecting your BNC cable to the ‘Video In’ from the camera you want to test.∙Once connected, you should instantly see an image from the camera appear. If you do not get an image, assure the camera is properly powered (either from the 12vDC port on the ITM9000or separately from a power source). Also check your BNC cable to assure it is properlyconnected and not damaged.∙From here, if the camera is controllable, use the ‘SET’ option to choose its protocol and other options. Assure if it requires RS485 to properly connect it to the side of the ITM9000 along withusing the provided RS485 cable that came with it.∙As above, you can tell the ITM9000 to record or to take a snapshot of the camera being shown.Step 3:Analog Video Generator: Use this function to test analog / HD-AVS cameras such as the option above.The difference with this test is you can also test video output to a monitor. You may choose fromdifferent screen tests to assure the monitor is outputting correctly and to aim the camera at it to besure the camera’s color settings are optimal.∙Start by connecting your camera to the ‘Video In’ of the ITM9000. You can then use the ‘Video Out’ to a monitor to display the test screens.∙You may change the video pattern of your liking. This allows you to aim the camera at themonitor to assure optimal coloring is set on the camera.∙At the top right, the interface will display the current resolution and frame rate if applicable.Step 4: RJ45 TDR Test: This test allows you to check Ethernet runs and will notate if there is any shorts or problems with the lines. For more information about TDR (Time-Domain Reflectometry), consult the linkbelow.https:///wiki/Time-domain_reflectometry∙Start by plugging in your Ethernet cable that you want to test to one of the two RJ45 ports on the ITM9000∙Use the correct ‘ZOOM’ button press to choose which port you want to test∙You will see the results start to complete based on if the cable has a short or not and whatdistance it is atStep 5: Network Analyze: This section allows you to test various operations on your network including IP sniffing, listing of different subnet addresses and ping IP/domains. It’s very useful to help discovernetwork issues pertaining to access certain IP/domin names.∙Start by attaching the ITM9000 to a network that you want to use to test. If wanting to start connections outside of your local network, assure it has internet access. Press the ‘SET’ buttonto set a valid address to the ITM9000. You may allow it to contact a DHCP server if one isavailable on the network you are attached to∙You may now use the various tool options on the right side of the interface to begin testing∙Use the fold out keyboard for more convenience of typing in internet addresses and domainsStep 6: Record Playback: This section allows you to review and playback video/snapshots that were taken during you tests above. Remember to look for the on screen option when viewing streams fromcameras to tell it to take snapshots. Typically the button for snapshots is ‘A’ and for video it is ‘Z’ on thefold out keyboard.∙When you access the menu, it will display a list of folders based on the date thesnapshots/video were taken. Use the ‘right’ arrow to access each folder when highlighted overit.∙You will see a list of snapshots and videos taken on that date. Use the ‘IRIS’ button to playthem back and pause. Use the ‘SCR/COM’ option to full screen.∙You may extract the media from the ITM9000 by using the USB cable provided. Simply plug one end to the ITM9000 and the other end to a Windows based PC. Go to ‘Settings’ on the mainmenu and choose ‘Start USB Storage’. You should get a prompt showing the ITM9000installing on the PC. It should then show as a removeable drive labeled ‘DATA’. Access this andyou should see all recorded media that you can drag and drop to your desktop.Reference / Additional NotesAdditional Reading: Please reference to the official manual that came with the device for more details.
