To Set Offset/Low Level
The DC offset setting range is limited by the “Impedance” and “Ampl/HiLevel”
settings. Please refer to the “Output Characteristics” in “Specifications”. The
default value is 0V
DC
.
The DC offset voltage displayed on the screen is the default value or the offset
previously set. When the instrument configuration (such as impedance) is changed,
if this offset is valid, the instrument will still use this offset; otherwise, the instrument
would display prompt message and set the offset to the offset upper limit of the new
configuration automatically.
Press Offset/LoLevel to highlight “Offset”. At this point, use the numeric keyboard
to input the desired offset value and then select the desired unit from the pop-up
menu.

The DC offset voltage units available are V
DC
and mV
DC
.

Press this softkey again to switch to low level setting. At this point, “LoLevel” is
highlighted.

The low level should be lower than the high level at least 1mV (the output
impedance is 50Ω).

The low 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.
