Set Amplitude
The settable range of amplitude is limited by the "frequency" setting. Please
refer to the description of "output characteristic" in "performance index". The
default is 5vpp.
Press the
FREQ
soft key to highlight the amplitude parameter. At this time,
use the direction key and the adjustment knob to set the value of the amplitude:
use the direction key to move the cursor to select the position to be edited, and
then rotate the knob to modify the value.

What is the difference between the amplitude in Vpp and the value in Vrms?
Answer
：
Vpp is the unit of signal peak value, Vrms is the unit of signal effective value. Vpp is
used by default.
Explain:
For different waveforms, the relationship between Vpp and Vrms is different. Take the
sine wave as an example.
The relationship is shown in the figure below.
According to the above figure, it can be deduced that the conversion relationship
between Vpp and Vrms meets the following relationship
：
Vpp = 2

Vrms
For example, for a sine wave with a current amplitude of 5Vpp, the converted value is
1.768Vrms.
