Ac Amplitude (High-Impedance) Verification - Keysight 33210A Service Manual

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
impedance to High–Z. Be sure the output is enabled.
