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

Parameters

Parameter Name	Parameter Type	Range of Values	Default Value

number	numeric	01 - 99	N/A

Comments Microwave Switch Module Model Number:

The SYSTem:CTYPe? <number> command returns (for both modules):

HEWLETT-PACKARD,E1368A,0,A.01.00

Note: The 0 after the module number is the serial number of the module (always 0). A.01.00 is an example of the module revision code number.

Example Reading the Model Number of a Card #1 Module

SYST:CTYP? 1

Returns 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 store 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 oldest error numbers/messages remain in the queue and the most recent are lost.

∙*RST Condition: *RST does not clear the error queue.

Example Reading the Error Queue

SYST:ERR?	Query the error queue, read and
	print the numbers/message.
