CALibration:STRing
Syntax
CALibration:STRing "<string>"
CALibration:STRing?
Description
This command allows you to store one message in calibration memory. For example, you can store such
information as the date when the last calibration was performed, the date when the next calibration is
due, the instrument's serial number, or even the name and phone number of the person to contact for a
new calibration.
For a more detailed discussion of the calibration procedures, see the Keysight
53210A/53220A/53230A 350 MHz Counter Service Guide. Please refer to the Ser-
vice Guide before attempting to calibrate the instrument. Improper use of the
CALibration commands can adversely affect the accuracy and reliability of the instru-
ment.

Remarks
l
You can record a calibration message only from the remote interface and only when the instrument is
unsecured (see CALibration:SECurity:STATeOFF command). You can read the message from either the
front-panel or over the remote interface. You can read the calibration message whether the instrument
is secured or unsecured.
l Storing a calibration message will overwrite any message previously stored in memory.
l The calibration message is stored in non-volatile calibration memory, and does not change when power
has been off, after a Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet
command).
Return Format
The query returns an ASCII string enclosed in double quotes. If no calibration message has been specified,
an empty quoted string ("") is returned.
