3 Spectrum Analyzer Mode
3.2 Swept SA Measurement
State Saved Part of the Input/Output system, which means it is loaded and saved with state
Range
ON|OFF
Annunciation The Source annotation in the Meas Bar shows Off if Source Mode is Off, “Trk, RF off” if Source Mode is
Tracking but RF is off, and “Trk, RF on” if Source Mode is Tracking and the RF output is on
Source Amplitude
Adjusts the power level of the selected source. Note that the actual amplitude is also
affected by Amplitude Offset and Power Sweep.
Remote Command
:SOURce[:EXTernal]:POWer[:LEVel][:IMMediate][:AMPLitude] <ampl>
:SOURce[:EXTernal]:POWer[:LEVel][:IMMediate][:AMPLitude]?
Example
:OUTP ON
:SOUR:POW -10dBm
Dependencies If the requested setting of Source Amplitude causes the calculated external source start or stop
Amplitude to exceed the external source capability, a warning status message is generated, “Data out
of Range; clipped to source max/min” The “Show Source Capabilities and Settings” menu can then be
examined to check the source capabilities
This parameter test and clip is also performed at source acquisition
See also "CXA-m TG Uncalibrated Amplitude Range" on page 455
Preset -10.00 dBm (On Source Preset and Restore Input/Output Defaults)
Not affected by Mode Preset
State Saved Part of the Input/Output system, which means it is Loaded and Saved with state
Min/Max The range of the amplitude parameter is dependent on the amplitude range of the source that is
selected, and the settings of Amplitude Offset and Power Sweep

Notes
This alias is for the ESA tracking generator. It specifies the source output power level at the start of the
power sweep, just as does :SOURce:POWer
Tracking Peak
Activates a routine that adjusts the delay of the instrument’s tuned frequency with
respect to the tracking generator output in order to guarantee that the
measurement is peaked in amplitude. This delay is automatically determined by the
instrument, in order to accommodate the delay of the DUT and its cables. The
