Amplitude vs. frequency characteristics
Connection:
Use coaxial cable to connect FUNCTION OUT to AC voltmeter 2 (50
Ω
termination).
Setting:
Initialize, then set the amplitude to 20 Vp-p/open and select the frequency and
waveform as indicated in the table.
Measurement:
Measure the true rms output voltage for each frequency and waveform.
Judgment:
The normal ranges are indicated in the table.
