Output Amplifier Adjustment (Optional)This adjustment procedure should only be performed following repairs to
the Output Amplifier circuitry. The adjustment improves the high frequency
performance of the Output Amplifier.
1Remove the function generator power and cover as described on page 130.
2Use a DMM to measure the ACrms voltage across J701 as shown below.
3Turn on the function generator.
4Set the function generator for a 1 kHz, 1V rms, sine wave output.
5Adjust R710 for a minimum reading on the voltmeter. Typical readings
are less than 0.005 Vrms.
6Replace the covers as described on page 130.
