Set the Amplitude
The amplitude range is limited by Frequency or Period and Impedance settings. Please
refer to "Output Characteristics" in Specifications. The default value is 200mVpp.
The amplitude displayed on the screen is the default value or the amplitude previously
set. When the instrument configuration (e.g. frequency) is changed, if this amplitude is
valid, the instrument will still use this amplitude; otherwise, the instrument would display
a prompt message and set the amplitude to the amplitude upper limit of the new
configuration automatically.

The high level units available are V and mV.
Tips:
Switch between Vpp and Vrms
Vpp is the unit for the signal peak-peak value and Vrms is the unit for the signal effective
value. The default unit of the instrument is Vpp. Users can quickly switch the current
amplitude unit from the front panel.
For different waveforms, the relations between Vpp and Vrms are different. Take sine
waveform as an example; the relation of the two units is as shown in the figure below.
