Download E1465A/E1466A/E1467A Relay Matrix Switch Modules

E1467A Matrix Module Model Number: SYSTem:CTYPe? <number> returns:
HEWLETT-PACKARD,E1467A,0,A.04.00
where the 0 after E1467A is the module serial number (always 0) and
A.4.1 is an example of the module revision code number.

SYSTem:ERRor?
SYSTem:ERRor? returns the error numbers and corresponding error
messages in the error queue of a matrix module. See Appendix C for a
listing of matrix module error numbers and messages.
Comments
Error Numbers/Messages in the Error Queue: Each error generated by a
matrix module stores an error number and corresponding error message
in the error queue. 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 SYSTem:ERRor? 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 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 errors are discarded.
