58502A Performance Tests
These 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 2-1,
“Recommended Test Equipment,” on page 2-4.
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.)

Input Level Response Tests
A 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.
Specifications Tested:
58502A Input Ranges
58502A Outputs, 50Ω load

The HP 54600B scope has only 1 MΩ input impedance. It does not allow you to switch or set the
impedance to 50Ω.
