Language Reference

 

 

 

 

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.)

 

 

 

 

 

There is a more detailed example in the “Improving the Speed of Your

NOTE

 

 

 

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.
