To Configure the Internal Oscillator as a Backup
(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
oscillator (Option 010), you only need to connect the 58502A to
ac power. The oscillator will provide the output signals. After powerup,
allow the oscillator to warm up for at least 5 minutes before using the
signals.
