200FPFiltered Tone ProbeDescriptionThe 200FP Filtered Tone Probe is designed to identify andtrace wires or cables within a group without need of removinginsulation. In addition, the 200FP has been specifically designed tofilter out all power-related noise to eliminate “Power Line Hum.”The unit is constructed of durable ABS plastic, and an optionalleather carrying case, 200C, is available.The 200FP is alsoavailable as part of the Model 801K kit.When the 200FP is ON but not detecting a signal, the signal LEDwill flash momentarily (every 4 seconds) as a visible ON indicatorand reminder. When a tone signal is detected by the probe, thesignal LED will serve as a signal strength indicator.The brighterthe LED, the stronger the tone signal detected.SafetySafety is essential in the use and maintenance of Tempo Toolsand equipment. This instruction manual and any markings on thetool provide information for avoiding hazards and unsafe practicesrelated to the use of this tool. Observe all of the safety informationprovided.Purpose of this ManualThis manual is intended to familiarize personnel with thesafe operation and maintenance procedures for the TempoCommunications 200FP Filtered Tone Probe. Please read thisentire manual before operating the tool, and keep this manualavailable to all personnel. Replacement manuals are availableupon request at no extra charge.Controls (See Figure 1)A long press of the main control button turns the unit OFF or ON,and the unit beeps to indicate the change. A lower pitch beepindicates that the unit is going OFF. An Auto-Off feature hasbeen incorporated to turn the 200FP OFF after 5 minutes to helppreserve battery life. When Auto-Off activates, a bee-bee-bee-beep sounds from the speaker to alert the user that the 200FP isnow OFF. When the battery voltage is low, the unit sounds threedescending tones when it is turned ON.Short presses of the main control button engage and disengagethe hum filter of the 200FP. The unit beeps to indicate the change– a single beep means it is entering the normal unfiltered mode, 52080289 REV01 © 2019 Tempo Communications Inc. 08/19Do not discard this product or throw away!For recycling information, go to .All specifications are nominal and may change as design improvementsoccur. Tempo Textron Inc. shall not be liable for damages resulting frommisapplication or misuse of its products.KEEP THIS MANUALmode the LED indicator operates in red color, and in filter mode the LED appears green.A volume control knob located on the right side of the 200FPallows the user to control the sensitivity and loudness of the probe output.OperationIdentification of wires and cables is accomplished by first connecting a tracing tone generator like the TempoCommunications 77HP , 77GX or AT8 to the wires being traced.In working cables that are terminated, connect one lead of the tone generator to a wire and the other test lead to earth or equipment ground. This allows localization of the cable and un-terminated cables, 1. To activate the 200FP , use a long press of the square main control button.Note: Changes in temperature and battery power can affect the frequency of tones produced by any given tone generator. Under certain conditions, a tone test set may produce frequencies that are similar to power line hum and cause them to be blocked by the 200FP’s filter mode.2. Prior to locating the tone at the far end of the cable or wire, confirm proper operation of the 200FP at the tone source. With the probe ON and in the filter mode (a short press of the control button and a green LED blink), listen for a solid single tone or a complete warble tone at the tone generator. If no tone or only “half ”of a warble tone is detected, use the 200FP in the “Normal” unfiltered setting or replace the battery in the tone generator.3. Once activated, the volume control can be adjusted to suit the environment. Loudness of the probe tone output can be increased to overcome noise (i.e., vehicular traffic, airplanes or machinery) or decreased to reduce interference or when working in noise sensitive areas.4. The 200FP is equipped with recessed ports for connecting a lineman’s butt set. Attaching the butt set automatically activates the probe when Talk mode is selected on the set.5. To activate the 200FP without depressing the main control button, silence the speaker, and use only the LED, attach a jumper between the two recessed tabs. This simulates connection of a butt set.6. Touch the tip of the 200FP to the insulation of each potential target conductor.7. Reception of tone will be loudest on the subject wire. (Reception of the tone may be improved by separating the wires from the group.)SpecificationsElectricalNominal Gain: 35 dBNominal Input Impedance: 100 MΩProbe Tip Resistance (minimum): 300 ΩBattery: One 9V alkalineNominal Battery Life: 50 hoursOvervoltage Protection: Cat I, 150V to GndPhysicalLength: 250 mm (9.85")Width: 32 mm (1.27")Depth: 35 mm (1.38")Weight: 142 g (5 oz)Operating/Storage ConditionsTemperature: 0 °C to 50 °C (32 °F to 122 °F)MaintenanceBattery Replacement1.

(15)TablesFilter Circuit vs. Filter Order (6)FilterPro Low-Pass Filter Design ProgramThe Texas Instruments FilterPro program makes it easy to design low-pass active filters. The program aids in the design of low-pass filters implemented with the Multiple Feedback (MFB)topology. Because there are instances where the Sallen-Key filter topology is a better choice, the program also supports Sallen-Key low-pass filter design.An ideal low-pass filter would completely eliminate signals above the cutoff frequency, andperfectly pass signals below cutoff (in the pass-band). In real filters, various tradeoffs are made attempting to approximate the ideal. Some filter types are optimized for gain flatness in the pass- band, some trade off gain variation (ripple) in the pass-band for steeper roll-off, still others trade off both flatness and rate of rolloff in favor of pulse-response fidelity. FilterPro supports the three most commonly-used all-pole filter types: Butterworth, Chebyshev, and Bessel.2 Fil t erPro TM MFB and Sallen-Key Low-Pass Filter Design ProgramSBFA001A Butterworth (maximally flat magnitude)This filter has the flattest possible pass-band magnitude response. Attenuation is –3 dB at the design cutoff frequency. Attenuation above the cutoff frequency is a moderately steep 20-dB per decade per pole. The pulse response of the Butterworth filter has moderate overshoot andringing.Chebyshev (equal ripple magnitude)Note: Mr. Chebyshev's name is also transliterated Tschebychev, Tschebyscheff or Tchevysheff.This filter type has steeper attenuation above the cutoff frequency than Butterworth. Thisadvantage comes at the penalty of amplitude variation (ripple) in the passband. UnlikeButterworth and Bessel responses, which have 3-dB attenuation at the cutoff frequency,Chebyshev cutoff frequency is defined as the frequency at which the response falls below the ripple band. For even-order filters, all ripple is above the 0-dB-gain dc response, so cutoff is at 0-dB (see Figure 1.) For odd-order filters, all ripple is below the 0-dB-gain dc response, so cutoff is at –(ripple) dB (see Figure 2.) For a given number of poles, a steeper cutoff can be achieved by allowing more pass-band ripple. The Chebyshev has even more ringing in its pulse response than the Butterworth.Bessel (maximally flat time delay)(Also called Thomson.) Due to its linear phase response, this filter has excellent pulse response (minimal overshoot and ringing). For a given number of poles, its magnitude response is not as flat, nor is its attenuation beyond the –3-dB cutoff frequency as steep as the Butterworth.Although it takes a higher-order Bessel filter to give a magnitude response which approaches that of a given Butterworth filter, the pulse response fidelity of the Bessel filter may make theadded complexity (because of additional filter sections) worthwhile.Fil t erPro TM MFB and Sallen-Key Low-Pass Filter Design Program 3SBFA001AFigure 1.

The advantages and disadvantages of the filter directly decide the quality of the products. The application of the active filter is more flexible and convenient. For the two common topological structures （MFB and Sallen⁃Key） of the active filter， the transfer functions of the two filters are derived and analyzed. The filter design software FilterPro made by Texas Instruments is used to design the active filter based on Butterworth according to the two topological structures. The designed two filters are simulated and verified by means of Multisim 14， which provides a certain theoretical basis for the design and application of the active filter in the future.Keywords： active filter； MFB； Sallen⁃Key； topology structure； FilterPro； Multisim 140 引言对于现代电子技术，滤波器作为信号处理中基础并且重要的电路单元，在许多领域都得到了广泛的应用，其中应用更为灵活的要属有源滤波器。

PREPARING THE PORTABLE FILTER1. Remove screen from over tubes/element with tongs or a Drain Clean OutRod (See Figure 1.1).SCREEN OVER TUBES/ ELEMENTS WILL BE VERY HOT AND SHOULD BE MOVED TO A SAFE PLACE.2. Heat fryers to 325°F. Stir oil thoroughly until all water is removed and shut fryer off (including pilot light) before filtering. (Figure 1.2)NOTE:Water settles in the cooler oil in the Cold Zone. If the water is notremoved, the filter paper absorbs the water preventing the oil from passing through it.OILIS HOT. USE CARE WHEN FIL TERING.3.Place in clean filter tub (See Figure 1.3):1st:Filter Screen2nd: Filter Paper (new sheet for each fryer)3rd:Hold down ring4th:Secure hold down ring at each corner with “T” rod handles 5th:Acidox filter powder (new powder for each fryer)6th:Strainer basketNOTE:Hold down ring makes a gasket-like seal on filter paper. Filter papermust be placed edge to edge from front to back, overlapping on sides. Filter Paper must be smooth and flat under hold down ring to get a proper seal. Lock the two tension arms into place by pushing down and rotating 90°.NOTE:One package of Acidox is needed for every 40 pounds of oil.B. FILTRATION1.Place filter under fryer drain. Screw drain extension tube in to drain valve if desired. Open main drain valve and let oil flow completely into filter (See Figure2.1).2.Turn on pump and flush all crumbs from bottom of fryer into filter. Flush out fryer completely (See Figure 2.2).3. Close fryer drain valve (See Figure 2.3).4.Clean fryer vessel with non-abrasive scrub pad & Keating Klenzer.5.

FilterPro 程序设计用于辅助低通滤波器设计，以实现多反馈(MFB)及Sallen-Key 拓扑。

本报告可作为FilterPro 操作指南，同时还包括了其他方面的问题，记述了设计人员涉足该程序的必备信息以及程序所交付的功能。

目录FilterPro 是德州仪器的注册商标。

该程序可辅助设计低通滤波器并实现多反馈点(MFB)拓扑。

由于在某些场合Sallen-Key滤波器拓扑更为优秀，因此该程序也支持Sallen-Key低通滤波器的设计。

理想的低通滤波器将完全消除截至频率以上的信号，并使得低于截至频率（处于通带内）的信号完好的通过。

但对实际的滤波器来说，需要做不同的折衷以逼近理想的状态。

某些滤波器类型针对通带内的增益平坦度作了优化，另一些则以通带内的增益变化（纹波）作为代价，折衷获取陡峭的滚降；还具有其他的滤波器类型，为了获取较好的脉冲响应保真度而同时对平坦度及滚降速率做了折衷。

FilterPro支持三种最常见的全极点滤波器类型：巴特沃兹、切比雪夫及贝塞尔。

ZHCA053FilterPro TM MFB 及Sallen-Key 低通滤波器设计程序巴特沃兹（最大幅度平坦度）该类型的滤波器具有尽可能平坦的通带幅度响应。

截止频率的衰减设计为–3 dB 。

高于截止频率的频带衰减具有适中的斜率—— 20 dB 滚降每十倍频程每极点。

巴特沃兹滤波器的脉冲响应具有适当的过冲(overshoot)及振铃(ring)。

切比雪夫（等纹波幅度）注释：切比雪夫(Chebyshev)先生的名字还被音译为Tschebychev 、Tschebyscheff 或Tchevysheff.与巴特沃兹滤波器相比，此类型的滤波器在通带以外的衰减更为陡峭——该优点是以牺牲通带内的幅度变化量（纹波）为代价的。

与巴特沃兹及贝赛尔响应（3 dB 衰减位于截止频率处）不同，切比雪夫滤波器的截止频率定义为响应滚降至低于纹波带的频点。

对于偶数阶滤波器而言，所有纹波均高于0 dB 了益的直流响应，因此截止频点位于0 dB 衰减处，如图1所示。

对于奇数阶滤波器来说，所有的纹波均低于0 dB 了益的直流响应，截止频率则定义为低于纹波带最大衰减点（- ripple dB 的频点），如图2所示。

在极点数量一定时，增加通带纹波可实现更陡峭截止。

相对于巴特沃兹滤波器而言，切比雪夫滤波器的脉冲响应具有更大的振铃。

贝赛尔（最大延迟时间平坦度）也称为汤姆逊(Thomson)型滤波器。

由于其线性相位响应特性，使得此类滤波器具有最优的脉冲响应（最小化过冲及振铃）性能。

对于给定的极点数量而言，贝赛尔的幅频响应并不如巴特沃兹平坦，-3 dB 截止频率以外频带的衰减也不如巴特沃兹陡峭。

尽管须采用更高阶的贝赛尔滤波器来逼近给定的巴特沃兹滤波器的幅频响应，但考虑到贝赛尔滤波器的脉冲响应保真度，增加一定的复杂性（源于附加的滤波器部件）也是物有所值的。

缺点：阶跃响应存在一定的过冲及振荡。

切比雪夫响应优点：与巴特沃兹相比，切比雪夫滤波器具有了更良好的通带外衰减。

缺点：通带内纹波令人不满，阶跃响应的振铃较严重。

贝赛尔响应优点：贝赛尔滤波器具有最优的阶跃响应——非常小的过冲及振铃。

缺点：与巴特沃兹相比，贝赛尔滤波器的通带外衰减较为缓慢。
