SYSTem

The SYSTem subsystem returns error numbers/messages in the error queue of a switchbox, and returns module types and descriptions in a switchbox.

:CDEScription? <number> :CTYPe? <number> :CPON <number> ALL

:ERRor? SYSTem:ERRor? returns the error numbers/messages in the error queue of a switchbox. See Appendix C for error message information.

Comments ∙ Error Numbers/Messages in the Error Queue: Each error generated by a switchbox stores an error number and corresponding error message in the error queue. The error number is always negative and the 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 *CLS.

∙Maximum Error Numbers/Messages in the Error Queue: The queue holds a maximum of 30 error numbers/messages for each switchbox. If it overflows, the last error 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?

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

Parameters

Parameter Name	Parameter Type	Range of Values

<number>	numeric	1-99

Comments	∙ RF Multiplexers Module Description:
	The SYST:CDESciption? <number> command returns: “ 50 Ohm RF
	Mux” for the HP E1366A or “ 75 Ohm RF Mux” for the HP E1367A.
Example Reading the Description of a Card #1 Module
	SYST:CDES? 1	! Return the description
:CTYPe?	SYSTem:CTYPe? <number> returns the module (card) type of a selected
	module in a switchbox.
