To Set Offset/Low Level
The DC offset setting range is limited by the "Impedance" and "Amplitude/High
Level" settings. The default value is 0 V
dc
.
The DC offset voltage displayed on the screen is the default value or the offset
previously set. When the instrument configuration (e.g. impedance) is changed, if
this offset is valid, the instrument will still use this offset; otherwise, the instrument
would display a prompt message and set the offset to the offset upper limit of the
new configuration automatically.
Tap the Offset parameter input field to input the desired offset value with the
numeric keypad, then select the unit. Tap "Ok".

The DC offset voltage units available are V
dc
and mV
dc
.

Tap the label again to switch to Low Level setting.

The low level should be at least 1 mV smaller than the high level (output
impedance: 50 Ω).

The low level units available are V and mV.
You can also use the arrow keys and the knob to set the parameter value: press
down the knob to enter the editing mode, use the arrow keys to move the cursor to
select the digit to be edited, and then rotate the knob to modify the value. Besides,
you can use the knob to switch between different parameters.
