When the :CALC:MATH:MEM command is executed on a particular corrected
data array, its copy is stored into the corrected memory array
corresponding to that corrected data array.
The instrument retains 16 corrected memory arrays at maximum, each of
which is associated with one of the 4 traces contained in one of the 4
channels (4 × 4 = 16). To read/write one of the corrected data arrays, use
the following command:
:CALC:DATA:RMEM
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 corrected data array.
Regardless of the data format, it contains two data elements per
measurement point as shown in the following table:
Data format
Data element (primary
value)
Data element
(secondary value)
log magnitude log magnitude Always 0
