Reading/Writing Measurement Data
Internal data processing
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 corrected memory array.
The instrument retains 16 formatted 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 formatted memory arrays, use the following command:
:CALC{1-4}:DATA:FMEM on page 216
Stimulus data arrays
A stimulus data array contains the stimulus values for all measurement points.
The instrument retains 4 stimulus data arrays at maximum, each of which is associated
with one of the 4 channels. Stimulus data arrays are read-only. To retrieve one of the
stimulus data arrays, use the following command:
:SENS{1-4}:FREQ:DATA? on page 416
Calibration coefficient arrays
A calibration coefficient array contains the calibration coefficients calculated based on the
results of measurement performed with standard devices.
The instrument retains 4 calibration coefficient arrays at maximum, each of which is
associated with one of the 4 channels. No commands are available that read or write
calibration coefficient arrays.
