CALibration:STRing

Syntax

CALibration:STRing <quoted_string>

CALibration:STRing?

Description

This command allows you to store one message in calibration memory in the mainframe. 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 34970A/34972A Service Guide. Please refer to that guide before attempting to calibrate the instrument as improper use of the CALibration commands can adversely affect the accuracy and reliability of the instrument.

Used With:

Internal DMM

Parameters

Name Type Range of Values Default Value

<quoted_string> Quoted ASCII String A string of up to 40 characters enclosed in quotes. You can use letters (A-Z), numbers (0-9), and special characters like "@", "%", "*", and so on. This is a required parameter.

Name	Type	Range of Values	Default Value
<quoted_string>	Quoted ASCII String	A string of up to 40 characters enclosed in quotes. You can use letters (A-Z), numbers (0-9), and special characters like "@", "%", "*", and so on.	This is a required parameter.

Remarks

You can record a calibration message only from the remote interface and only when the instrument is unsecured (see CALibration:SECure:STATe OFF 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.
The calibration message may contain up to 40 characters. From the front panel, you can view only 13 characters of the message at a time.
From the front panel, commas, periods, and semicolons share a display space with the preceding character, and are not considered individual characters.
Storing a calibration message will overwrite any message previously stored in memory.
The calibration message is stored in non-volatile 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.

Examples

The following command stores a message in calibration memory in the mainframe.

CAL:STR "CAL: 18 Aug 2009" or CAL:STR 'CAL: 18 Aug 2009'

The following query returns the message currently stored in calibration memory in the mainframe (the quotes are also returned).

CAL:STR?

Typical Response: "CAL: 18 Aug 2009"
