:MEMory Subsystem
This subsystem manages the instrument's memory.
COMMAND
:MEMory:DATA . . . <name>,<data>
Stores and queries data in the named power calibration table.
QUERY
RESPONSE
– Data points are returned in
<definite length arbitrary block>
format.
– A data point consists of comma-separated, NRf format number pairs.
COMMENTS
– Valid table names:
8481A
,
8481D
,
8482A
,
8485A
,
8487A
,
CUST1
,
CUST2
,
CUST3
– Valid data is stored in non-volatile memory. Any error in a data block causes all
data in that block to be ignored and the data currently in the named profile to
be retained.
– Data must be input in the form of two to ten comma-separated, NRf-format
number pairs.
– The data-point number pairs in the named profile are automatically sorted by
frequency value before the profile is stored.
– When a calibration table is in use, the instrument uses the data points in the
currently selected table to determine the amount of loss correction to apply.
– If the measured frequency is between two defined data points, the instrument
uses the two defined data points to linearly interpolate the appropriate
correction value.
– If the measured frequency is above the highest frequency value in the profile
(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).
