Range:
Increment:
*RST:
BB:MCCW:CFAC:MODE SLOW
sets the Target Crest optimization mode.
BB:MCCW:CFAC 10 dB
sets the desired crest factor to 10 dB.
Example:
[:SOURce<hw>]:BB:MCCW:CFACtor:MODE <Mode>
The command sets the mode by which automatic settings will minimize the crest factor
or hold it at a chosen value.
Parameters:
OFF|CHIRp|SLOW
OFF
Crest factor optimization is switched off. The carrier PHASE
setting has an effect.
CHIRp
The crest factor is very rapidly optimized to < 3 dB for multi carrier
signals so that all carriers are switched on and have the same
amplitude. The computation time is independent of the number of
carriers. In other carrier configurations the achievable crest factor
is worse.
SLOW
The crest factor entered using SOURceBB:MCCW:CFACtor is
maintained for all carrier configurations by means of automatic
settings. The computation time depends on the number of carriers
and on the crest factor that has been set. Computation time
increases only when the number of carriers exceeds 256 and the
crest factor is above 4 dB.
CHIRp
<Mode>
*RST:
BB:MCCW:CFAC:MODE OFF
switches off automatic crest factor optimization.
The setting SOURBB:MCCW:CARR:PHAS has an effect.
Example:
[:SOURce<hw>]:BB:MCCW:CLOCk?
The command queries the output clock rate. The output clock rate depends on the num-
ber of carriers an the selected carrier spacing.
Return values:
