CALCulate Subsystem
Example: To query the mean power of a set of GSM bursts:
1. Set the waveform measurement sweep time to
acquire at least one burst.
2. Set the triggers such that acquisition happens at a
known position relative to a burst.
3. Then query the mean burst levels using,
CALC:DATA2:COMP? MEAN,24e-6,526e-6 (These
parameter values correspond to GSM signals, where
526e-6 is the length of the burst in the slot and you
just want 1 burst.)
NOTE There is a more detailed example in the “Improving the Speed of Your
Measurements” section in the E4406A programmer’s guide.
Remarks: The optional parameters must be entered in the
specified order. For example, if you want to specify
<length>, you must also specify <soffset>.
This command uses the data in the format specified by
FORMat:DATA, returning either binary or ASCII data.
