Internal data arrays

Unformatted data arrays
An unformatted array contains the raw data just as it was obtained through measurement
and divided for each trace.
The instrument retains the unformatted data arrays which are associated with each trace of
individual measurements. To read/write one of the unformatted data arrays, use the
following command ("xx" specifies any one of the measurements (PN,SP,FP,TR,USER)
while "y" specifies the number of the trace if the measurement has multiple traces.
• :CALC:xx[1-1]:TRAC[1-y]:DATA:UDAT
There is an unformatted data array formatted in dBc only when the phase noise
measurement is performed.
:CALCulate:PN[1-1]:TRACe[1-1]:DATA:PDATa on page 132
•
Unformatted memory arrays
When the :CALC:xx[1-1]:TRAC[1-y]:MATH:MEM command is executed on a particular
unformatted memory array, a copy is stored in the corresponding unformatted data array.
The instrument retains the unformatted memory arrays associated with each trace of
individual measurements. To read/write one of the unformatted memory arrays, use the
following command:
• :CALC:xx[1-1]:TRAC[1-y]:DATA:UMEM
There is an unformatted memory array formatted in dBc only when the phase noise
measurement is performed.
:CALCulate:PN[1-1]:TRACe[1-1]:DATA:PMEMory on page 132

Formatted data array
A formatted data array contains the formatted data (values to be displayed) obtained by
performing data math operations, measurement parameter conversion, and smoothing on a
particular unformatted data array.
The instrument retains the formatted data arrays associated with each trace of individual
measurements. To read/write one of the formatted data arrays, use the following command:
• :CALC:xx[1-1]:TRAC[1-y]:DATA:FDAT
Formatted memory arrays
A formatted memory array contains the formatted data (values to be displayed) obtained by
performing data math operations, measurement parameter conversion, and smoothing on a
particular unformatted memory array.
The instrument retains the formatted memory arrays associated with each trace of
individual measurements. To read/write one of the formatted memory arrays, use the
following command:
• :CALC:xx[1-1]:TRAC[1-y]:DATA:FMEM
