×:Switches 1, 2, and 3 can be
* 1:Maximum output level
Connect a distortion meter to the output. Apply a f=1 kHz, 1 Vp-p sine wave to the input and adjust the input level so that the output distortion becomes 1.0%.
The maximum output level Vom (Vp-p) is the output voltage at that time.
* 2:Voltage gain
Apply a f=1MHz, 2.0 Vp-p sine wave to the input.. The voltage gain GV=20log[VOUT/VIN] (dB).

Apply a f=1MHz, 2.0 Vp-p sine wave to the input. The voltage gain is calculated as follows: GV=20log[VOUT/VIN] (dB)
* 3:Total harmonic distortion
Apply a f=1kHz, 1.0 Vp-p sine wave to the input and measure by connecting a distortion meter to the output.
