3.3 Instrument subsystem command
67
Key Entry:
【
Signal
】 —>[LFM]—> [BandWidth]
[:SOURce]:PULM:LFM:DIRection <Mode>
Function: This command is used for setting LFM direction. When LFM Direction is set to Increase,
the FM signal output of the signal generator will increase progressively from negative
to positive bandwidth; when the direction is set to Decrease, it will change from
positive to negative bandwidth. After turning off LFM, the instrument will turn off pulse
modulation and IQ modulation automatically.
Setting format: [:SOURce]:PULM:LFM:DIRection POSitive|NEGative
Query format: [:SOURce]:PULM:LFM:DIRection?
Parameter:
<Mode> Discrete data. Options for LFM Direction are:
POSitive | 0: Increase,
NEGative | 1: Decrease.
Example: [:SOURce]:PULM:LFM:DIRection POS LFM Direction is Increase.
Reset status: POS

Signal
】 —>[LFM]—> [LFM Direction]
[:SOURce]:PULM:LFM:STATe <State>
Function: This command is used for setting LFM. When LFM is set to ON, the signal generator will
initiate pulse modulation and IQ modulation automatically. After turning off LFM, the
instrument will turn off pulse modulation and IQ modulation automatically.
Setting format: [:SOURce]:PULM:LFM:STATe ON|OFF|1|0
Query format: [:SOURce]:PULM:LFM:STATe?
Parameter:
<State> Boolean data is as follows:
ON | 1: LFM ON,
OFF | 0: LFM OFF.
Example: [:SOURce]:PULM:LFM:STATe 1 LFM is ON.
Reset status: 0
