Figure 4-3:
Setting instrument amplitude
NOTE A momentary disruption in the output waveform may occur while changing amplitude. You
can disable the voltage auto ranging function (refer to Setting voltage auto ranging) to
prevent output disruption.
To set output amplitude from a remote interface:
VOLTage {<amplitude>|MINimum|MAXimum}
Use this command to set units:
VOLTage:UNIT {VPP|VRMS|DBM}
Setting DC offset voltage
The default DC offset voltage for all functions is zero (0) V.
To set DC offset voltage, use one of these two methods:
Method A
1. Press the function key of your selection.
2. Press the soft key under Vos / Low. Ensure Vos is highlighted (Figure 4-4).
3. Use the navigation wheel with the cursor keys, or the numeric keypad to change the value.
You can change the units by using the numeric keypad in combination with the soft keys.

Setting DC offset voltage
Method B
1. Press the Utility key.
2. Press the soft key under DC to choose DC / ON. Ensure ON is highlighted.
3. Use the navigation wheel with the cursor keys, or the numeric keypad to change the value.
You can change the units by using the numeric keypad in combination with the soft keys.
To set DC offset voltage from a remote interface:
VOLTage:OFFSet {<offset>|MINimum|MAXimum}
NOTE Method B can be used to specify a DC voltage line out only. Also, if you use it to
set the DC offset voltage; it will hold the setting when you enter the function key
of your selection.
