:PA:OUTPut:POLarity
Syntax
:PA:OUTPut:POLarity {NORMal|INVerted}
:PA:OUTPut:POLarity?
Description
Set the output polarity of the signal at the output terminal of the PA to normal
(NORMal) or inverted (INVerted).
Query the output polarity of the signal at the output terminal of the PA.
Parameter
Name
Type
Range
Default
{NORMal|INVerted}
Discrete
NORMal|INVerted
NORMal
Explanation
The output polarity of the signal at the output terminal of the PA refers to whether
the signal at the output terminal of the PA is outputted in normal (NORMal) mode or
inverted (INVerted) mode. In the normal mode, the signal is outputted normally; in
the inverted mode, the signal is inverted and then outputted.
Return Format
The query returns NORMAL or INVERTED.
Example
:PA:OUTP:POL NORM /*Set the output polarity of the signal at the output
terminal of the PA to NORMal*/
:PA:OUTP:POL? /*Query the output polarity of the signal at the output
terminal of the PA and the query returns NORMAL*/
:PA:SAVE
Syntax
:PA:SAVE
Description
Save the current working state of the PA into the internal memory of the
instrument.
Explanation
The instrument will load the working state stored automatically when the PA is
turned on the next time.
:PA[:STATe]
Syntax
:PA[:STATe] {ON|1|OFF|0}
:PA[:STATe]?
Description
Turn on or off the external power amplifier.
Query the on/off status of the external power amplifier.
Parameter
Name
Type
Range
Default
{ON|1|OFF|0}
Bool
ON|1|OFF|0
OFF
Explanation
When the external power amplifier is turned on, the PA amplifies the input signal
(namely the output signal of the signal generator) and then outputs the signal.
When it is turned off, there is no output from the PA.
Return Format
The query returns ON or OFF.
Example
:PA ON /*Turn on the external power amplifier*/
:PA? /*Query the on/off status of the external power amplifier and the query
returns ON*/
