Chapter 2 Performance Tests
58502A Performance Tests58502A Performance TestsThese tests verify the specified electrical performance of the 58502A Distribution Amplifier. The tests do not require access to the inside of the instrument and do not test typical specifications or supplementary characteristics.
If the performance test is to be considered valid, the following conditions must be met:
•Instrument being tested is powered on and warmed up.
•Tests are conducted as presented in this section.
•Tests are conducted under normal operating conditions as stated in Chapter 7, “Specifications.”
•Test equipment is selected according to the Table
Equipment
•HP 8663A Signal Generator or equivalent
•HP 3400B RMS Voltmeter or equivalent
•50Ω BNC Feedthrough: HP 10100C or equivalent (Use the 50Ω
feedthrough if you are using the HP 54600B Oscilloscope; however, if you are not using this scope DO NOT use the 50Ω feedthrough.)2
Input Level Response TestsA 10 MHz signal is input to the 58502A from a signal generator. The level of this signal is adjusted from +7 dBm to +15 dBm while the twelve Outputs are verified for a 0.707 to 1.12 Vrms signal.
