×: Any of switches 1, 2, or 3 possible.

∗ 1: Connect a distortion meter to the output, and input a f = 1kHz sine wave. Adjust the input level until the output distortion is 1.0%. This output voltage

at this time is the maximum output level Vom (VP-P).

∗ 2: Input a 2.0VP-P, 1MHz sine wave. The voltage gain is given by GV = 20 log (VOUT / VIN)(dB).

∗ 3: Input a 1.0VP-P, 1kHz sine wave. Connect a distortion meter to the output and measure the total-harmonic distortion.
