(dBm Impedance Default command) Sets the power-up and reset default impedance used
for dBm outputs (ac volts).
Parameters: Z50 (50 ohms)
Z75 (75 ohms)
Z90 (90 ohms)
Z100 (100 ohms)
Z135 (135 ohms)
Z150 (150 ohms)

Z1000 (1000 ohms = dBv)
Z1200 (1200 ohms)
Example: DBMZ_D Z600
This setting only applies when single output AC voltages are being sourced. The dBm
impedance is set to the default at power on, reset, and when going 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 returned.
Parameter: <value> signed offset amplitude
Example: DC_OFFSET +123.45 MV
Load a dc offset of +123.45 mV to the ac output signal.
