(Option 010)
Connect the input signal to input A . Then connect the 58502A to
ac power. The internal oscillator will provide the source signal for the
58502A only if input A signal fails. After powerup, allow the oscillator
to warm up for 5 minutes before using the signals.
To Configure the Internal Oscillator as the Only
Source Input (Option 010)
If the 58502 Distribution Amplifier contains the optional quartz
