7-6 WF1946B
Amplitude accuracy
Connection: Use coaxial cable to connect FUNCTION OUT to AC voltmeter 1.
Setting: After setting initialize, set the amplitude, output range and waveform as indicated in
the following table.
Measurement: Measure the true rms output voltage for each waveform. (CH1,CH2)
Judgment: The normal ranges are indicated in the table.
