:MEMory Subsystem

This subsystem manages the instrument’s memory.

COMMAND :MEMory:DATA . . . <name>,<data>

Stores and queries data in the named power-correction profile.

QUERY RESPONSE • Data points are returned in <definite length arbitrary block> format.

• A data point consists of two to ten comma-separated, NRf format

number pairs.

COMMENTS • Valid profile names: CORR1, CORR2, . . . CORR9

• 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 power correction is in use, the Counter uses the data points in

the currently selected profile to determine the amount of loss

correction to apply.

• If the measured frequency is between two defined data points, the

Counter 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 Counter determines a

loss-correction value 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).
