362 Agilent X-Series Signal Generators SCPI Command Reference
Digital Signal Interface Module Commands
Digital Subsystem—Option 003 and 004 ([:SOURce])
approximately 0.28 dBc/Hz. The effect of this value can be determined by examining the graphic on
the front panel or the actual output.
The signal generator has an automatic DAC over- range protection feature that is always on for this
subsystem.
NOTE The amplitude range varies depending on the f2 value (see the
“:DIGital:DATA:INPut:PHASe:NOISe:F2” on page 361). As f2 increases in value, the
range for Lmid decreases. If the current Lmid setting is too high for the new f2 value,
the signal generator changes the Lmid value and generates an error.
NOTE The phase noise is added to the base phase noise of the instrument.
The range values are expressed in units of dBc/Hz.

Key Entry Desired Flat Amplitude (Lmid)
:DIGital:DATA:INPut:PHASe:NOISe:LMID:ACTual?
Supported N5172B/82B with option 004
:DIGital:DATA:INPut:PHASe:NOISe:LMID:ACTual?
This SCPI command returns the actual Lmid in use with the current set of desired values. This
value may vary if the desired f2 value is changed, and may or may not vary when Lmid is varied,
based on the capabilities of the hardware.
