2.To Output Basic WaveformJU

PSG9080 function/arbitrary waveform generator can output basic
waveforms (Sine wave, square wave, triangle wave and pulse wave) from oneof the channels separately or from the two channels at the same time. At
start-up, the dual channels are configured to output a sine waveform with
10kHz frequency and 5Vpp amplitude by default. Users can configure theinstrument to output various basic waveforms.

Auto power-on: You can turn on and off the auto power-on through the softkeys【ON】 and 【OFF】. After the auto power-on function is turned on, theinstrument output is powered on by default.
CH1/CH2 amplitude fine-tuning: When the output amplitude of theCH1/CH2 channel waveform is slightly different from the measured amplitude,
you can change the value of the CH1/CH2 amplitude fine-tuning and perform
online calibration to obtain accurate amplitudes. The default CH1/CH2
amplitude fine-tuning value is 50.
