Basic Function Commands
Digital Modulation Subsystem—N5182A ([:SOURce])
:DM:SOURce
Supported N5182A
[:SOURce]:DM:SOURce EXTernal|INTernal|SUM
[:SOURce]:DM:SOURce?
This command selects the I/Q modulator source.
This softkey is found under the I/Q menu.
EXTernal This choice selects a 50 ohm impedance for the I and Q input connectors and
routes the applied signals to the I/Q modulator.
INTernal This choice selects the internal baseband generator as the source for the I/Q
modulator and requires Option 651/652/654.
Sum This choice selects the internal baseband generator and combines that signal with
an external source and routes the applied signals to the I/Q modulator and
requires Option 651/652/654.
*RST INT
:DM:STATe
Supported N5182A
[:SOURce]:DM:STATe ON|OFF|1|0
[:SOURce]:DM:STATe?
This command enables or disables the I/Q modulator.
The I/Q modulator is enabled whenever a digital format is turned on.
The I/Q annunciator will be shown on the signal generator display whenever the I/Q modulator is
on.
ON (1) This choice enables the internal I/Q modulator.
OFF (0) This choice disables the internal I/Q modulator. You can turn off the I/Q
modulation with this choice even though a digital modulation format is enabled.
With this configuration, the RF output signal will not be modulated, but the I/Q
signals may be present at the rear panel I and Q outputs depending on the rear
panel output selection.
