Storing and Loading Calibration Parameters
It is recommended that you save all the calibration parameters in a
text file so they can be reloaded in the event of a flash failure or a
mistake in calibration.
To get the calibration data, execute the following commands and
save the response in a text file:
The SCPI command (s) to download all the calibration data are:
[:]CALibration:PARameter[:OUTPut]
[:]CALibration:PARameter:APRogram?
[:]CALibration:PARameter:INPut?
The response to these commands are in the 488.2 Arbitrary
Program Block Data format.
If the calibration ever needs to be restored, you can execute the
same commands and write the arbitrary block data response that
was received in the query as the parameter.
For example, downloading the parameter data can be done from
the hyper terminal as follows.
:cal:par?
#2 62#h2710,#h0000,#h2710,#h0000,#h2710,#h0000,#h2710,
#h0000,#h1AA4
:cal:par:apr?
#259#h7B,#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,
#h 7F, #h7F
:cal:par:inp?
#227#h2710,#h00,#h2710,#h00
To restore the unit with a set of previously saved calibration values
can be done as follows.
:cal:par
#262#h2710,#h0000,#h2710,#h0000,#h2710,#h0000,#h2710,#h0
000,#h1AA4
:cal:par:apr
#259#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,#h7F,#h7
F,#h7F
:cal:par:inp
#h227#h2710,#h00,#h2710,#h00
By saving and reloading the calibration parameters using these
commands, you can calibrate the unit for maximum accuracy for a
specific load and then switch loads and load a calibration set that is
accurate at maximum accuracy for the new load.
