TE5251
User Manual
4-44
Description
This command programs the CW frequency. Note that the CW waveform is sine only and its frequency
setting is separate to the standard sine waveform. The CW frequency setting is valid for all modulation
types.
Parameters
Name Range Type Default Description
<frequency> 10 to
100e6
Numeric 1e6 Programs the frequency of the carrier waveform in
units of Hz. Note that the CW waveform is sine only
and its frequency setting is separate to the standard
sine waveform.
Response
The 5251 will return the current carrier frequency value.
MODulation:CARRier:BASeline{CARRier|DC}(?)
Description
This command will program the carrier baseline when the modulation is used in triggered mode.
Parameters
Name Type Default Description
CARRier Discrete CARR This selects the carrier as the baseline for the
modulation function, when operating in one of the
interrupted run modes. The output will generate
continuous, none modulated sinusoidal waveform
(CW) until triggered, upon trigger will generate the
modulated waveform and then resume generating
continuous CW.
DC Discrete This selects DC level as the baseline for the
modulation function, when operating in one of the
interrupted run modes. The output will generate
continuous DC until triggered, upon trigger will
generate the modulated waveform and then resume
generating continuous DC level.
Response
The 5251 will return CARR, or DC depending on the present carrier baseline setting.
MODulation:LOAD:DEMO
Description
This command will load demo table to the memory. The table type depends on the selected modulation
function. Table will be loaded for the following functions: (n)PSK, User PSK, (n)QAM and User QAM.
