Return Format
The command returns an ASCII string with the following format (the string is enclosed in double quotes). To read the string into your computer, be sure to dimension a string variable with at least 73 characters.
Agilent Technologies,<Model Number>,<Serial Number>,<Firmware Rev>
A 10-digit string is returned for the Serial Number field. The Firmware Revision has the form R.RR and indicates the revision of firmware currently in use on the specified module.
For the 34923A, 34925A, and 34933A modules, the Model Number may include a suffix to indicate a single-ended (1-wire) configuration. For example, the response for the 34923A will be either "34923A" (differential mode) or "34923A-1W" (single-ended mode).
For the 34951A module, the command also returns the FPGA revision number:
Agilent Technologies,<Model
Number>,<Serial Number>,<Firmware Rev>
If the specified slot is empty, the command responds with "Agilent Technologies,0,0,0".
If a module is installed in the specified slot but cannot be properly identified, the command responds with an "Unknown Card ID" string. An error is also generated and reported to all I/O sessions.
If a module is installed in the specified slot but a firmware incompatibility exists or a self-test error has occurred, the command responds with a "Boot Error" string. An error is also generated and reported to all I/O sessions.
Example
The following command returns the identity of the module in slot 3 (the quotes are also returned).
SYST:CTYP? 3
Typical Response: "Agilent Technologies,34921A,MY12345678,1.00"
