Measuring up and earning a spot is the driving idea behind Keysight Technologies, Inc.’s FieldFox analyzers. It starts with adaptability: every operating mode is flexible enough to meet the needs of novices and experts alike. To accelerate your work, each mode has a task-driven interface that saves time in the field. Best of all, FieldFox is designed to withstand your toughest working conditions.FieldFox is ideal for performing cable and antenna (CAT) measurements. Key CAT measurements include:–Distance-to-fault, return loss, VSWR, and cable loss (1-port and 2-port) –Integrated QuickCal - no calibration kit required–4/6/6.5/9/14/18/26.5 GHz Step up to FieldFox -- and achieve more in the field.Boost your readiness FieldFox–Ready to sweep the line at power on (CalReady)–Working in the dusk or rain–Screen is clearly viewable under direct sunlight–Easy file transfer between FieldFox and PC–Datalink Software provides simple and easy reporting–Future proof with software licensing upgradeConvenient side strap makes it easyTask-driven keys are grouped to easily perform fieldmeasurementsPortrait design and large buttons for easy operation – even with gloves onDedicated marker function access11.5”(292 mm)7.4”(188 mm)(N9912A 4/6 GHz)Convenient side strap makes it easyTask-driven keys are grouped to easily perform fieldmeasurementsPortrait design and large buttons for easy operation – even with gloves onDedicated marker function access11.5”(292 mm)7.4”(188 mm)N9913A/14A/15A/16A/17A/18A…and depend on its durability and convenienceLEFT SIDERIGHT SIDESimplify interference analysis with AM/FM tune and listenBuilt-in DC supply for powering external bias-tees, probes, and active devicesKeep going with field-swappablebatteries that last up to 3 1/2hoursports from moistureSpectrum analyzer 25 MHz IF out usable SD flash card for data storageUSB ports for easy data storageexternal trigger outputand SCPI porgrammingTOPPort 1/RF outputConnector bay protects RF connectorsGet precise location using the built-in GPS receiverExternal reference and Port 2/SA RF inputQuick connect shoulder strap clipsCable and antenna analyzerFifty to sixty percent of microwave-link equipment issues are related to cables, antennas and connectors. Degraded feeder lines cause poor coverage, link failures, and reduced sensitivity on the receive path.To maintain the quality of a RF/MW link,it is critical to keep the cable and antenna systems in good working condition.Use FieldFox to make return loss, VSWR, insertion loss, 1-port cable loss, and distance-to-fault measurements. You can test antennas, cables, filters, and amplifiers with a single instrument. The amplifiers can be biased using FieldFox’s built-inDC source.Distance to faultWhen the return loss of any given feeder line system, including the antenna, failsto meet specification, the next step isto find which part of the system failed. The distance to fault measurement or DTF is used to transfer frequency domain measurements to distance domain. This helps the user locate the discontinuity in feeder line.FieldFox can make both return loss and distance-to-fault measurements at the same time. This helps you correlate overall system degradation with specific faults inthe cable and antenna system. The built-incable editor allows you to edit existingcable types on-site, and save them as newcable types with user defined names.Return loss/VSWRmeasurementsReturn loss /VSWR is the single mostimportant parameter to measure andverify a cable and antenna system. Thismeasurement reflects the power transferefficiency of a given system. It combineswith the distance-to-fault measurement, tohelp users quickly identify where the faultyRF components are.View and control the RL and DTF displays independentlyVSWR measurementCable and antenna analyzer measurementsFieldFox’s waveguide distance-to-fault measurement Cable loss measurement (1-port)If RF and microwave cables have beeninstalled on a tower or a building, likea distributed antenna system (DAS), itbecomes difficult to measure cable lossby accessing both ends of the cableunder test. FieldFox allows users to makesingle-port cable-loss measurements withhigher accuracy close to the insertionloss measurement and provides a higherdynamic range for longer cables.One-port cable loss measurementCable and antenna measurementsInsertion lossThe insertion loss measurementcharacterizes the loss of a jumper cable,feeder cable, a connector, or an attenuatorif both ends are accessible. It can alsomeasure the filter type of devices likediplexer, duplexer, tower mounted amplifier(TMA), low noise amplifier (LNA) and bi-directional amplifier (BDA) etc. For amplifiermeasurements, it measures gain instead ofloss of the device.Insertion loss displayWaveguide measurementsThe Waveguides are widely used toprovide transmission links betweenmicrowave transmitters and antennas, aswaveguides have less loss than coax. Dueto the dispersion nature of a waveguide,it is always a challenge to figure out thevelocity factor (VF) of a particular typeof waveguide in DTF (distance-to-fault)measurements. FieldFox can help youautomatically calculate waveguide VF whenthe waveguide type is chosen.CalReady – calibrated at power on, ready to goSave time and get right to work withFieldFox’s CalReady feature. With CalReady, the analyzer is already calibrated and ready to make measurements such as return loss, VSWR, 1-port cable loss, and DTF measurements without having to connect/ disconnect additional calibration devices.Hassle-free calibration in the ield with the industry’s irst and only QuickCalFieldFox is the industry’s first and only handheld network analyzer with a built-in calibration capability that allows you to calibrate the network analyzer without carrying a calibration kit (cal kit) into the field. With any other test instrument, when you add additional devices to the test port, such as jumper cables or adapters, you need to recalibrate using a cal kit. QuickCal eliminates the need to carry and use a cal kit, and also provides worry-free accuracy. FieldFox’s QuickCal supports measurements such as insertion loss/gain, 1-port cable loss, return loss, and DTF.Mechanical calibrationFieldFox supports a wide selection of mechanical calibration kits, such as T cal kits for various frequency ranges. You also CalibrationBroadband CalFieldFox allows you to make broadband calibrations, which means the instrument is calibrated over the maximum frequency range. After a broadband calibration, you can change the frequency range or number of points without recalibrating the instrument. The calibration is interpolated, and accuracy is maintained.Fast and accurate calibration with ECalThe FieldFox calibration engine supports Keysight’s USB ECal modules. ECal support reduces calibration time and the need to make multiple connections during testing, while also providing for greater consistency between measurements. For FieldFox users, that translates into fewer human errors and increased accuracy.Waveguide calibrationKeysight offers both high-performance and also economical waveguide calibration kits. The economical kits (N9911X) are ideal for field maintenance and troubleshooting, as they provide good measurement results atlower costs.FieldFox’s QuickCal allows you to perform calibrations without carrying a cal kitSTEP 1STEP 2STEP 3Keysight N9911x economicalCarry FieldFox wherever you need to go–Kit friendly 3.0 kg or 6.6 lbs–Large buttons are easy to operate, even when wearing gloves–Field swappable battery lasts up to 4 hours–Non-slip rubber grip securely fits in your hands and won’t slide off the hood of your vehicle–Vertical “portrait” orientation makes it easy to hold and operate at the same timeLarge buttons make it easy to perform spectrum analysis measurements – even with gloves onDesigned for you and the work you do everydayRugged enough to meet MIL-specs –Completely sealed instrument enclosureprovides measurement stability in harshenvironments–Specially designed connector bay protects RF connectors from damage due to drops or other external impacts (designed to withstand 4’ drop on concrete surface on all 6 faces)–Water-resistant chassis, keypad and case withstand wide temperature ranges and salty, humid environments –Case withstands shock and vibration–Wide operating temperature –10 to +55 °C (14 to 131 °F)–Wide storage temperature –51 to +71 °C (–60 to 160 °F)–Meets MIL-PRF-28800F Class 2 requirements–Type tested and meets MIL-STD-810G, Method 511.5, Procedure I requirements for operation in explosive environments–Meets IEC/EN 60529 IP53 requirements for protection from dust and waterModern connectivity–Two USB 2.0 ports can be used for data transfer, USB power sensor support, USB keyboard and mouse support–LAN port: used for SCPI programming, FieldFox Datalink software connection, and remote control via iOS device–SD flash card slot: use as a data storage deviceTranslective display and backlitkey The display is designed for easy viewing in indoor and outdoor settings and in direct sunlight and darkness.

频谱分析仪技术指标的定义
频谱分析仪技术指标的定义（1）频率稳定度：频率或幅度在一段时间内保持不变的能力，在频谱仪中，稳定度是指本振固定在一个特殊频率上的能力。
（2）分辨率带宽（RBW）：频谱仪区分两个相邻输入正弦信号的能力。
（-3dB点对应的带宽）。
（3）选择性：测试正弦信号时的-60dB/-3dB 带宽比。
与进行FFT 运算时所采用的数字滤波器的形状有关。
（4）带宽精度：实际的－3dB带宽值对应标称值的误差范围。
（5）视频带宽（VBW）：在频谱分析仪中用图像（滤波）带宽表示图像显示电路的可调低通滤波器的3分贝点截止频率。
当它等于或小于分辨率带宽时，图像显示电路不能完全响应包络检波器的快速变化信号。
结果看到的测量曲线是平滑的，平滑程度由图像滤波器带宽与分辨率带宽的比决定。
（6）相位噪声：频率的极短期变化由相位噪声指标给出。
相位噪声以在对源频率的某一频率偏移上归一化到1Hz带宽的dBc（相对于“载波”或源频率的dB数）表示，典型的指标表述为在10kHz偏移处 < -90dBc（1Hz BW）。
（7）显示平均噪声电平：在无信号输入下，本机噪声的平均值。
测试结果与分辨率带宽有关，分辨率带宽缩小10倍则相位噪声电平减少10dB。
（8）二次谐波：在信号的频谱里，二倍于基波信号频率的信号分量。
用二次谐波信号与基波信号的幅度差值来表示。
（9）三阶互调：是指当两个信号在一个线性系统中，由于非线性因素存在使一个信号的二次谐波与另一个信号的基波产生差拍（混频）后所产生的寄生信号。
（10）剩余响应：是无信号输入情况下，在频谱仪显示中出现的离散响应。
是由于混频过程中频谱仪内部信号的不完全屏蔽产生的。
（11）幅度精确度：幅度测量的不确定度，有相对和绝对精度之分。
（12）显示动态范围：大小信号都能被同时显示在屏幕上的最大动态范围，对于每格10dB对数显示的频谱分析仪而言，实际动态范围会高于显示动态范围。
（13）失真：信号波形在传输系统中不期望的变化。

使用Agilent N9322C做标量传输测量
Solutions for简介在射频设计或者射频故障诊断过程中，通常需要评估一些有源或者无源器件的关键指标，但不需要相位信息，比如: 滤波器的3 dB 带宽、插损和抑制度，放大器的增益和1 dB 压缩点等是否满足需求，这样的测试通常就可以由标量网络分析仪完成。
频谱分析仪加上跟踪源选件实质上就是一台单端口的标量网络分析仪。
使用频谱分析仪的跟踪源进行标量传输测量(S 21)操作介绍— Agilent N9322C 射频频谱分析仪应用系列之一技术论文Agilent N9322C 射频频谱分析仪加上跟踪源选件 (N9322C-TG7), 不但有频谱分析仪的功能，而且还具备了标量网络分析仪的测试功能。
Agilent N9322C 7-GHz 频谱分析仪标量网络分析仪提供了激励-响应的测试能力，激励-响应测试主要用于测试被测件的传输参数S21和反射参数S11。
通过传输测试，可以获得被测件的增益、频响、插损和平坦度指标情况; 通过反射测试，可以得到被测件的回波损耗指标。
Agilent N9322C跟踪源选件的相应指标如下：频率o 范围: 5 MHz 至 7 GHzo 分辨率: 1 Hzo 分辨率带宽: 3 kHz 至 3 MHz输出功率o 范围: –20 至 0 dBmo 分辨率: 1 dB测量动态范围o Max. Output power 至 D ANL with 3 kHz RBWAgilent N9322C传输测量操作步骤本文只阐述传输测试的操作步骤，关于反射测试，请参考N9322C反射测量文档。
被测件和N9322C的测试连接如图1所示，但为了保证传输测试结果精确，通常需要进行下面简述的三步操作：1. 根据被测件的实际需求来设置N9322C的频率、分辨率带宽、扫描时间、输入衰减、跟踪源的输出信号幅度等。
2. 移去被测件，使用标准连接器来替代被测件，使N9322C的跟踪源输出端口与其射频输入端口直接连接，然后打开归一化功能，确定一个0 dB的参考线。

频谱分析仪的使用方法
频谱分析仪的使用方法频谱分析仪的使用方法（第一页）13MHz信号。
一般情况下，可以用示波器判断13MHz电路信号的存在与否，以及信号的幅度是否正常，然而，却无法利用示波器确定13MHz电路信号的频率是否正常，用频率计可以确定13MHz电路信号的有无，以及信号的频率是否准确，但却无法用频率计判断信号的幅度是否正常。
然而，使用频谱分析仪可迎刃而解，因为频谱分析仪既可检查信号的有无，又可判断信号的频率是否准确，还可以判断信号的幅度是否正常。
同时它还可以判断信号，特别是VCO信号是否纯净。
可见频谱分析仪在手机维修过程中是十分重要的。
另外，数字手机的接收机、发射机电路在待机状态下是间隙工作的，所以在待机状态下，频率计很难测到射频电路中的信号，对于这一点，应用频谱分析仪不难做到。
一、使用前须知在使用频谱分析仪之前，有必要了解一下分贝(dB)和分贝毫瓦(dBm)的基本概念，下面作一简要介绍。
1．分贝(dB)分贝是增益的一种电量单位，常用来表示放大器的放大能力、衰减量等，表示的是一个相对量，分贝对功率、电压、电流的定义如下：分贝数：101g(dB)分贝数=201g(dB)分贝数=201g(dB)例如：A功率比B功率大一倍，那么，101gA／B=10182’3dB，也就是说，A功率比B功率大3dB，2．分贝毫瓦(dBm)分贝毫瓦(dBm)是一个表示功率绝对值的单位，计算公式为：分贝毫瓦=101g(dBm)例如，如果发射功率为lmw，则按dBm进行折算后应为：101glmw／1mw=0dBm。
如果发射功率为40mw，则10g40w／1mw--46dBm。
二、频谱分析仪介绍生产频谱分析仪的厂家不多。
我们通常所知的频谱分析仪有惠普(现在惠普的测试设备分离出来，为安捷伦)、马可尼、惠美以及国产的安泰信。
相比之下，惠普的频谱分析仪性能最好，但其价格也相当可观，早期惠美的5010频谱分析仪比较便宜，国产的安泰5010频谱分析仪的功能与惠美的5010差不多，其价格却便宜得多。
