AC Amplitude (high-impedance) Verification
This procedure checks the ac amplitude output accuracy at a frequency of 1 kHz,
and establishes reference measurements for the higher frequency flatness
verification procedures.
1 Set the DMM to measure Vrms Volts. Connect the DMM as shown below.
2 Set the instrument to each output described in the table below and measure
the output voltage with the DMM. Press to set the output impedance to
High–Z. Be sure the output is enabled.
