AC amplitude (high-impedance) adjustment
The instrument stores a calibration constant for each high-impedance attenuator path. Each path's gain coefficient
is calculated using two measurements: one with the waveform DAC at + output and one with waveform DAC at –
output. The setups, therefore, must be performed in pairs.
1. Connect the multimeter to the channel output as shown below.
2. Use the multimeter to measure the DC voltage at the front panel connector for each setup in the following table.
