58502A Operational Verification
These following procedures check the standalone functionality of the
58502A Broadband Distribution Amplifier.
Equipment
• Signal Generator: HP 8663A
• Oscilloscope: HP 54600B
•50Ω BNC Feedthrough: HP 10100C (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.)
1
• BNC Cables (1 meter, male-to-male)
CAUTION Input amplitude at the 58502A input A or B connector must be below
5 Vrms (+27 dBm) or damage to the Amplifier will occur.
NOTE If any of these verification procedures fail, try repeating them. If
failure still occurs, refer to Chapter 6, “Service,” in this guide for fault
determination and instructions on returning the defective unit for
repair.
Outputs (1-12) Verification
1 Apply power to the 58502A and verify successful completion of self-test
before proceeding to step 2. (See the subsection “To Connect AC Power”
on page 1-5 in Chapter 1 of this guide, if needed.)
NOTE Once the 58502A Distribution Amplifier has powered on, all that is
required for operation is an input signal connected to either the
input A or B, located on the rear-panel.
2 Set the HP 8663A Signal Generator to the following conditions:
Frequency: 10 MHz
Wave type: Sinusoidal
Amplitude: +10 dBm

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