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. (CH1,CH2)
Judgment: The normal ranges are indicated in the table.

Sinewave distortion
Connection: Use coaxial cable to connect FUNCTION OUT to a distortion meter (50
Ω
termination).
Setting: Initialize, then set the amplitude to 20 Vp-p/open and the frequency as indicated in the
table.
Measurement: Measure the distortion (CH1,CH2)
Judgment: The normal range is indicated in the table.
