This setting only applies when single output AC voltages that are sourced. The dBm
impedance is set to the default at power on, reset, and when you go into single output AC
mode.

(DC Voltage Offset command) Applies a dc offset to an ac output voltage (maximum six
digits). This command applies only to single ac voltage outputs. If the selected offset is
too large for the active ac voltage range, an error message is shown.
Parameter:
<value> signed offset amplitude
Example:
DC_123.45 MV
Install a dc offset of +123.45 mV to the ac output signal.
