To Set Amplitude/High Level
The amplitude setting range is limited by the “Impedance” and “Freq/Period” settings.
Please refer to “Output Characteristics” in “Specifications”. The default value is
5Vpp.
The amplitude displayed on the screen is the default value or the amplitude
previously set. When the instrument configuration (such as frequency) is changed, if
this amplitude is valid, the instrument will still use this amplitude; otherwise, the
instrument would display prompt message and set the amplitude to the amplitude
upper limit of the new configuration automatically. Users can also use “High Level” or
“Low Level” to set the amplitude.
Press Ampl/HiLevel to highlight “Ampl”. At this point, use the numeric keyboard to
input the desired amplitude value and then select the desired unit from the pop-up
menu.
 The amplitude units available are Vpp, mVpp, Vrms, mVrms and dBm (invalid in
HighZ).
 Press this softkey again to switch to high level setting. At this point, “HiLevel” is
highlighted.
 The high level units available are V and mV.
Users can also use the direction keys and knob to set the parameter value: use the
direction keys to move the cursor to select the digit to be edited and then rotate the
knob to change the number.
KEY POINTS:
1． How to convert the amplitude in Vpp to the corresponding value in
Vrms?
Method:
Vpp is the unit for signal peak-peak value and Vrms is the unit for signal
effective value. The default unit is Vpp. Press · in the numeric board to
quickly switch the current amplitude unit.
Note:
For different waveforms, the relation between Vpp and Vrms is different. The
relation of the two units is as shown in the figure below (take sine waveform
as an example).
