SYSTem, CDEScription? | HP FET MULTIPLEXER E1351A/53A instruction

SYSTem

	The SYSTem subsystem returns the error numbers and error messages in
	the error queue of a switchbox, and returns the types and descriptions of
	modules (cards) in a switchbox.
Subsystem Syntax	SYSTem
	:CDEScription? <number>
	:CPON <number ALL>
	:CTYPe? <number>
	:ERRor?
: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	∙ 16-Channel FET Multiplexer Module Description: The
	SYSTem:CDEScription? <number> command returns:

16 Channel FET Mux

∙16-Channel Thermocouple FET Multiplexer Module Description:

The SYSTem:CDEScription? <number> command returns:

16 Channel FET Mux with T/C

Example Reading the Description of Card #1 Module

SYST:CDES? 1

Determine the description.

:CPON SYSTem:CPON <number ALL> opens all channels of a selected module, or all modules (cards) in a switchbox.

Parameters

Parameter Name	Parameter Type	Range of Values

number	Numeric	1 - 99 ALL

Comments ∙ Differences between *RST and CPON: SYSTem:CPON only opens all channels of a selected module or all modules in a switchbox. *RST opens all channels of all modules in a switchbox and also sets the trigger modes to the power-on states.

Example Opening All Channels on Card #1

SYST:CPON 1

Opens all channels on card #1.
