HP8920A综合测试仪使用说明HP8920A/B综合测试仪使用方法一、测试线的连接MAX PWR 60W——仪器射频信号输入输出（注意观察标注的最大功率值，可能有些仪器只能测试5W或者10W的功率）。
接被测试机器的天线头。
（此处不能接错！200mw的那个头不要输入大功率，否则，会损坏仪器！）AUDIO IN （HI）——音频信号输入（接对讲机外接耳机插孔，输入信号后仪器显示相应指标）。
AUDIO OUT——音频信号输出（接对讲机外接话咪插孔，仪器里面模拟出来的音频信号经过话咪插孔进入到对讲机里面进行调制，然后通过仪器显示相关指标）。
其它部分按钮说明：VOLUME：调节仪器蜂鸣器声音大小。
SQUELCH：旋钮上的色点一般调节在中心位置合适，不然，有噪声。
二、测试1、发射测试（检测机器时，一般先测发射，因为发射部分的一些指标不良，会影响到接收）：按仪器面板上的“TX”按键，进入发射指标检测界面。
连接好对讲机各测试线并打开电源，按下对讲机的PTT按键，发射时，主要看仪器屏幕上的三个指标：Tx Frequency ：频率误差（实际发射出来的频率值和该信道标称频率的差值，一般±500Hz即可。
Tx Power：功率大小FM Deviation：最大频偏（一般在4KHz左右，加亚音频之后，会高0.7KHz。
该指标影响对讲机的送话）。
在发射状态下，把仪器的滤波器调小：即把“Filter 1”选择到“＜20Hz”，再把“Filter 2”选择到“300Hz”，即可以在“FM Deviation”这一栏直接查看到该信道所加的模拟亚音频数值。
2、接收测试：按仪器面板上的“RX”按键，在该界面，要设置以下参数：转动面板上的那个大的旋钮，让光标停留在“RF Gen Freq”处，直接按数字键和单位按键，即输入要测试对讲机的接收频率（如458.825MHz），然后，再把光标移到“Amplitude”这一项，分别输入1mv和0.25uv两种场强参数（看你自己的习惯，也可以用“－DBm”的单位），以检测机器的失真度和灵敏度。

FLUKE 8922A8920A, 8921A & 8922AAutorangingFluke's autoranging feature allows you to carry out your testing without having to change ranges manually. A range can be placed on HOLD or manually stepped up to a higher range. On HOLD, the meter will remain in a given range regardless of changes in input levels. On STEP UP, the meter will increase ranges step-by-step until the switch is released. Peaking/Dipping MeterIn addition to an accurate digital display, all Fluke Voltmeters in the 8920-Series feature an analog meter for peak and null voltage adjustments. The meter indicates O to 100 percent full scale in each range.Linear Analog OutputModels 8920A and 8922A are equipped with a rear panel output for driving X-Y or st d p chart recorders, delivering voltages proportional to the display count. A 2-volt level equals 2000 counts, a 1-volt level equals 1000 counts, etc. This feature is not available on Model 8921A. AccuracyFluke Digital Voltmeters avoid the possibilities for error so common in analog meters. The digital displays eliminate the likelihood of misreading the meter due to viewing angle problems of parallax common with analog meters. Also, the accuracy of 8920-Series Voltmeters is specified as a percent of reading rather than as percent of full scale.Percent of reading accuracy does not degrade for measurements at the low end of a scale. Front panel switching offers a choice of readings in dB or volts.Technical SpecificationsThe a ccuracy s pecifications b elow apply from 9% to 100% of full scale and from 18°C to 28°C for 90 days.

Si8920 Data SheetIsolated Amplifier for Current Shunt MeasurementThe Si8920 is a galvanically isolated analog amplifier. The low-voltage differential input is ideal for measuring voltage across a current shunt resistor or for any place where a sensor must be isolated from the control system. The output is a differential analog sig-nal amplified by either 8.1x or 16.2x.The very low signal delay of the Si8920 allows control systems to respond quickly to fault conditions or changes in load. Low offset and gain drift ensure that accuracy is maintained over the entire operating temperature range. Exceptionally high common-mode transient immunity means that the Si8920 delivers accurate measurements even in the presence of high-power switching as is found in motor drive systems and inver-ters.The Si8920 isolated amplifier utilizes Silicon Labs’ proprietary isolation technology. It supports up to 5.0 kVrms withstand voltage per UL1577. This technology enables higher performance, reduced variation with temperature and age, tighter part-to-part matching, and longer lifetimes compared to other isolation technologies.Automotive Grade is available for certain part numbers. These products are built using automotive-specific flows at all steps in the manufacturing process to ensure the robust-ness and low defectivity required for automotive applications.KEY FEATURES•Low voltage differential input•±100 mV and ±200 mV options•Low signal delay: 0.75 µs•Input offset: 0.2 mV•Gain error: <0.5%•Excellent drift specifications•1 µV/°C offset drift•10 ppm/°C gain drift•Nonlinearity: 0.025% full-scale•Low noise: 0.10 mVrms over 100 kHz bandwidth•High common-mode transient immunity: 75 kV/µs•Compact packages•16-pin wide body SOIC•8-pin surface mount DIP•–40 to 125 °C•AEC-Q100•Automotive-grade OPNs available•AIAG compliant PPAP documentationsupport•IMDS and CAMDS listing supportIndustrial Applications•Industrial and renewable energy inver-ters•AC, Brushless, and DC motor controlsand drives•Variable speed motor control in consum-er white goods•Isolated switch mode and UPS powersuppliesSafety Regulatory Approvals•UL 1577 recognized•Up to 5000 Vrms for 1 minute •CSA component notice 5A approval •IEC 60950-1 (reinforced insulation)•VDE certification conformity•VDE0884 Part 10 (basic/reinforcedinsulation)•CQC certification approval•GB4943.1Automotive Applications •Hybrid and EV traction inverters •Onboard chargers•Charging pedestalsSi8920 Data SheetOrdering Guide 1.

Revision History (23)System Overview 2. System OverviewThe input to the Si8920 is designed for low-voltage, differential signals. This is ideal for connection to low resistance current shunt measurement resistors. The Si8920A has a full scale input range of ±100 mV, and the Si8920B has a full scale input range of ±200 mV. In both cases, the internal gain is set so that the full scale output is 1.6 V.The Si8920 modulates the analog signal in a unique way for transmission across the semiconductor based isolation barrier. The input signal is first converted to a pulse-width modulated digital signal. For transmission across the isolation barrier, the signal is further modulated with a high frequency carrier. On the other side of the isolation barrier, the signal is demodulated and the carrier portion is removed. The resulting PWM signal is then used to faithfully reproduce the analog signal. This solution provides exceptional signal bandwidth and accuracy.AONFigure 2.1. Functional Block Diagram3. Current Sense ApplicationIn the driver circuit presented below, the Si8920 is used to amplify the voltage across the sense resistor, RSENSE, and transmit the analog signal to the low-voltage domain across an isolation barrier. Isolation is needed because the voltage of RSENSE with respect to ground will swing between 0 V and the high voltage rail connected to the drain of Q1.To 3.3 to 5VLow Side Gate Driver Floating Gate Driver High Figure 3.1. Current Sense ApplicationThe load in this application can be a motor winding or a similar inductive winding. In a three-phase motor drive application, this circuit would be repeated three times, one for each phase. RSENSE should be a small resistor value to reduce power loss. However, an ex-cessively low resistance will reduce the signal-to-noise ratio of the measurement. Si8920 offers two specified full-scale input options,±100 mV (Si8920A) and ±200 mV (Si8920B), for optimizing the value of RSENSE.AIP and AIN connections to the RSENSE resistor should be made as close as possible to each end of the RSENSE resistor as trace resistance will add error to the measurement. The input to the Si8920 is differential, and the PCB traces back to the input pins should run in parallel. This ensures that any large noise transients that occur on the high-voltage side are coupled equally to the AIP and AIN pins and will be rejected by the Si8920 as a common-mode signal.The amplifier bandwidth of the Si8920 is approximately 950 kHz. If further input filtering is required, a passive, differential RC low-pass filter can be placed between RSENSE and the input pins. Values of R1 = R2 = 20 Ω and C1 = 10 nF, as shown in Figure 4.8 Step Response Low to High on page 11, provides a cutoff at approximately 400 kHz. For the lowest gain error, R1 and R2 should always be less than 33 Ω to keep the source impedance sufficiently low compared to the Si8920 input impedance.The common-mode voltage of AIN and AIP must be greater than –0.2 V but less than 1 V with respect to GNDA. To meet this require-ment, connect GNDA of the Si8920 to one side of the RSENSE resistor. In this example, GNDA, RSENSE, the source of Q1, and the drain of Q2 are connected. The ground of the gate driver (Silicon Labs’ Si8234 in this circuit) is also commonly connected to the same node.The Q1 gate driver has a floating supply, 24 V in this example. Since the input and output of the Si8920 are galvanically isolated from each other, separate power supplies are necessary on each side. Q3, R3, C3, and D1 make a regulator circuit for powering the input side of the Si8920 from this floating supply. D1 establishes a voltage of 5.6 V at the base of Q3. R3 is selected to provide a Zener current of 10 mA for D1. C3 provides filtering at the base of Q3, and the emitter output of Q3 provides approximately 5 V to VDDA. C2is a bypass capacitor for the supply and should be placed at the VDDA pin with its return trace connecting to the GNDA connection at RSENSE.C4, the local bypass capacitor for the B-side of Si8920, should be placed closed to VDDB supply pin with its return close to GNDB. The output signal at AOP and AON is differential with a nominal gain of 8.1 (Si8920B) or 16.2 (Si8920A) and common mode of 1.1 V. The outputs are sampled by a differential input ADC. Depending on the sample rate of the ADC, an anti-aliasing filter may be required. A simple anti-aliasing filter can be made from the passive components, R4, C6, and R5. The characteristics of this filter are dictated by the input topology and sampling frequency of the ADC. However, to ensure the Si8920 outputs are not overloaded, R4 = R5 > 5 kΩ and C6 can be calculated by the following equation:C 6=12×π×(R 4+R 5)×f 3dBCurrent Sense Application4.
