:CTYPe? SYSTem:CTYPe? <number> returns the module (card) type of a selected module in a switchbox.

Parameters

Parameter Name	Parameter Type	Range of Values

number	Numeric	1 - 99

Comments ∙ 16-Channel FET Multiplexer Module Model Number:

The SYSTem:CTYPe? <number> command returns:

HEWLETT-PACKARD,E1351A,0,A.03.00

∙16-Channel Thermocouple FET Multiplexer Module Model Number: The SYSTem:CTYPe? <number> command returns:

HEWLETT-PACKARD,E1353A,0,A.03.00

Note: The first number after the model number is the serial number of the module (always 0); the module revision code follows the serial number (for example, A.03.00).

Example Reading the Model Number of a Card #1 Module

SYST:CTYP? 1

Determine the model number.

:ERRor? SYSTem:ERRor? returns the error numbers and corresponding error messages in the error queue of a switchbox. See Appendix C for a listing of the switchbox error numbers and messages.

Comments ∙ Error Numbers/Messages in the Error Queue: Errors generated by a switchbox stores an error number and corresponding error message in the error queue. Each error message can be up to 255 characters long.

∙Clearing the Error Queue: An error number/message is removed from the queue each time the SYSTem:ERRor? command is sent. The errors are cleared first-in, first-out. When the queue is empty, each following SYSTem:ERRor? command returns 0, "No error". To clear all error numbers/messages in the queue, execute the *CLS command.

∙Maximum Error Numbers/Messages in the Error Queue: The queue holds a maximum of 30 error numbers/messages for each switchbox. If the queue overflows, the last error number/message in the queue is replaced by -350, "Too many errors". The least recent error numbers/messages remain in the queue and the most recent are discarded.

Example Reading the Error Queue

SYST:ERR?

Query the error queue.
