2Set Synthesizer #1 (i.e., the HP 3325B that is connected to the rear-panel Ref In input of the Counter via a 50Ω feedthrough) to output a 10 MHz, 200 mV rms sine wave signal.

3Set Synthesizer #2 (i.e., the HP 3325B that is connected to Channel 1) to output a 2 MHz, 100 mV rms square wave signal.

Verify the Counter displays a reading of approximately 2 MHz and the ExtRef annunciator is lit.
