Chapter 5 Technical Indicators and Indicator Tests General Characteristics 2.1 Environmental Requirements Working temperature range: 0℃~+40℃ Storage temperature range: -40℃~+70℃ 2.2 Power Conditions AC 220V±10%, 50Hz±5%. Section 2 Indicator Tests Let’s take the indicator testing of 3871FB solid-state power amplifier as an example, which can be used as a reference for other models of solid-state power amplifiers. - Page 11 Chapter 5 Technical Indicators and Indicator Tests Gain testing steps: Turn on the power of the amplifier and 3672 for preheating for 30 minutes. Set 3672 to [Test], [S21], [Format], [Log Amplitude], power of -40dBm, frequency of 32 GHz to 40 GHz, frequency sweep time of 1s, and number of measurement points of 101.
- Page 12 Chapter 5 Technical Indicators and Indicator Tests the signal source connected to the input port of the amplifier to 0dBm or any other value that can make the amplifier in the working state of saturated output, record the reading on the power meter at each test frequency point, and calculate the sum of the max.
- Page 13 Chapter 5 Technical Indicators and Indicator Tests test method of 1dB compression point for the output power of the amplifier, and record the difference between the peak value of fundamental wave and the non-harmonic wave of the spectrum analyzer, which should meet the indicator requirements at most operating frequency points.

Chapter 6 Maintenance and Repair Chapter 6 Maintenance and Repair Section 1 Regular Maintenance Testing and Calibration 387XX series solid-state power amplifiers should be tested and calibrated regularly on a yearly basis. The testing period should be reduced accordingly if the instruments are working in severe environments. Surface Cleaning Wipe the front panel and the housing with a cloth dipped in a neutral detergent, and then wipe it with a dry cloth.
