4.4.8 To Set Amplitude
a) Setting procedure
1.
Press the shortcut-key AMPTD to open
the amplitude input field. Or select the
[Amplitude] field and then press the
ENTER key.
[Amplitude] is displayed at the first page.
If [High] is displayed in the [Amplitude]
field, press the AMPTD key again.
2.
Select the digit to be changed by using the right or left arrow key, and then use the up or
down arrow key or the modify knob to increment the value. The change is immediately
reflected to the output.
Or use the numeric keypad to enter the value.
Press the ENTER key or the unit key (soft-key) to set the input value and reflect it to the
output.
b) To change units (Vp-p, Vpk, Vrms, dBV, dBm, User-defined unit)
1.
When the input field of Amplitude opens,
press the soft-key [Unit] to move the
cursor to the unit position at the right
end.
2.
The unit can be changed by using the
up or down arrow key/modify knob. Only
the display unit is changed without
changing the actual output value.
c) Available units differ depending on the waveform.
Vp-p, Vpk, Vrms, dBV, dBm, and user-defined units can be used as the units for amplitude.
However, the waveforms to which the units can be applied are restricted as follows (DC is
excluded from amplitude settings).
Unit Applied waveform
Vp-p Standard waveforms with amplitude rage of ±FS and arbitrary waveforms
Vpk Standard waveforms with amplitude rage of 0/+FS, -FS/0 and arbitrary
waveforms
Vrms Sine wave and noise
dBV Noise of sine wave.
1Vrms shall be 0dBV.
dBm Sine wave and noise.
The voltage that is 1mW at the specified load impedance shall be 0dBm.
For example, when the load impedance is set as 50Ω,
0dBm=223.6mVrms/50Ω.
It is not available when the load impedance is set as Hi-Z.
