90 Agilent X-Series Signal Generators SCPI Command Reference
Basic Function Commands
Vector Modulation Subsystem—N5172B/82B ([:SOURce]:IQ)
NOTE: This phase noise is added to the base phase noise of the instrument.
f2 must always be greater than or equal to f1. Setting f2 less than f1 will cause f1 to be set to the
value of f2.
*RST 30 kHz
Range 0 Hz to 77.50052449 MHz
Key Entry Desired Start Freq(F2)
:OUTPut:IMPairments:PHASe:NOISe:LMID
Supported N5172B with Option 653 or 655, N5182B with Option 656 or 657
[:SOURce]:IQ:OUTPut:IMPairments:PHASe:NOISe:LMID <value>
[:SOURce]:IQ:OUTPut:IMPairments:PHASe:NOISe:LMID?
This command sets the desired flat phase noise power (Lmid). The actual value can vary by
approximately 0.28 dBc/Hz. The effect of this value can only be determined by examining the graphic
on the front panel or the actual output.
NOTE: This phase noise is added to the base phase noise of the instrument.
*RST -70 dBc/Hz
Range - 300 dBc/Hz to 100 dBc/Hz
The range of Lmid varies depending on the value of the stop frequency (f2). The
range decreases as f2 increases.
Key Entry Desired Flat Amplitude(Lmid)
:OUTPut:IMPairments:PHASe:NOISe[:STATe]
Supported N5172B with Option 653 or 655, N5182B with Option 656 or 657
[:SOURce]:IQ:OUTPut:IMPairments:PHASe:NOISe[:STATe] ON|OFF|1|0
[:SOURce]:IQ:OUTPut:IMPairments:PHASe:NOISe[:STATe]?
This command enables or disables the real- time phase noise impairment.
NOTE: This phase noise is added to the base phase noise of the instrument.
The actual performance of the phase noise can only be determined by examining the graphic on the
front panel or the actual output, as the parameters simply guide the phase noise response.
*RST 0
Key Entry Phase Noise On Off
:OUTPut[1]:TRIGger:CONTinuous[:TYPE] FREE|TRIGger
Supported N5172B with Option 653 or 655, N5182B with Option 656 or 657
[:SOURce]:IQ:OUTPut[1]:TRIGger:CONTinuous[:TYPE] FREE|TRIGger
[:SOURce]:IQ:OUTPut[1]:TRIGger:CONTinuous[:TYPE]?
This SCPI command sets the behavior of the per output channel triggering.
