Vpp is the unit for signal peak-peak value and Vrms is the unit for signal
effective value. The default unit 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.
The relation of the two units is as shown in the figure below (take sine
waveform as an example).
Vpp=2Vamp
Vrms=0.707Vamp
Vamp
According to the figure above, the conversion relation between Vpp and
Vrms fulfills the following equation:

For example, to convert 2Vpp to the corresponding value in Vrms,
press · in the numeric keyboard and select Vrms menu. For sine
waveform, the converted value is 707.2mVrms.
