:MEMory Subsystem

This subsystem manages the instrument's memory.
:MEMory:DATA . . . <name>,<data>
COMMAND
Stores and queries data in the named power calibration table.
– Data points are returned in <definite length arbitrary block> format.
QUERY
RESPONSE
– A data point consists of comma-separated, NRf format number pairs.
– Valid table names: 8481A, 8481D, 8482A, 8485A, 8487A, CUST1, CUST2,
COMMENTS
– Valid data is stored in non-volatile memory. Any error in a data block causes all
– Data must be input in the form of two to ten comma-separated, NRf-format
– The data-point number pairs in the named profile are automatically sorted by
– When a calibration table is in use, the instrument uses the data points in the
– If the measured frequency is between two defined data points, the instrument
– If the measured frequency is above the highest frequency value in the profile

uses the two defined data points to linearly interpolate the appropriate
correction value.
(or below the lowest frequency value), the instrument determines a calbration
factor by using the two highest (or lowest) defined data points to extrapolate a
linear extension to the curve above the highest data point (or below the lowest
data point).
