AC amplitude (high impedance) verification

This test checks AC amplitude output accuracy at 1 kHz frequency using each attenuator.

1. Set the multimeter to measure Vrms. Connect the multimeter to the channel output as shown above.

2. Set the instrument to each output in the table below and measure the output voltage with the multimeter. Be

sure the output impedance is set to High–Z and the output is enabled.

[b] Use the following sequence to set this output:

1. Set amplitude to 400.0 mVrms
2. Set DC Offset to 1.0 VDC
3. Set Auto-Range to OFF
4. Set DC Offset Voltage to 0.0 VDC
5. After the measurement, set autorange ON for remaining measurements.

3. Compare the measured value to the test limits shown in the table.

4. For EDU33212A only. Connect multimeter to channel 2 output and repeat steps 2 and 3.
