:CALibration:DATA <arbitrary block>
Sets or queries the calibration data (input gain, input offset, reference oscillator,
and time interval).
Before performing calibration, it is a good idea to query (:CAL:DATA?) and store
the current calibration values in your program or on a disk in case an error occurs
during the calibration process. See the sample program "How to Read and Store
Calibration Information " in Chapter 3, "Programming Your Universal Counter for
Remote Operation."

Definite Length Block.

Programming Guide
Your Counter was calibrated before it left the factory. When you receive your
Counter, read the calibration count to determine its initial value.
Early versions of the Counter do not support this query.
The query response will be #256<56 calibration-data bytes> terminated
with a new line and EOI.
This command does not affect the interpolator calibration data.
If the <arbitrary block> command parameter has the incorrect number of
bytes or does not checksum, error -220 is generated.
If the update to EEPROM fails, error +2013 is generated.
The calibration data (updated by this command) is stored in
non-volatile memory, so cycling power will not reset these values. The only
way to update the calibration data is through this command or by initiating the
individual calibrations (see :DIAG:CAL: ...).
The calibration data (updated by this command) is unaffected by power-on,
save/recall, and *RST.
