DIAGnostic:CLOSe?

DIAGnostic:CLOSe <relay>{,<relay>...} returns a number to indicate the closed state of each relay in the list. Since these are Form C relays, “closed” means the relay is “set” (COMMON to NO).

Parameters

Name	Type	Range of Values

<relay>	numeric	001-003011-014021-024031-034041-044

Comments Relay Closure Results. The output buffer contains an unquoted string containing the result for the relay(s): 0 = Not closed (COMMON to NC) and 1 = Closed (COMMON to NO)

Invalid Values. Values other than those listed in the table cause error 2022, “Invalid relay number”.

Querying Relays. To query single relays, use DIAG:CLOS abc. To query multiple relays, use DIAG:CLOS? abc,def,ghi,... etc.

80 Relays Maximum. The E1470A has only 80 relays. Setting more than 80 relay numbers causes error: -108, “Parameter not allowed”.

Example	Querying Relay Closures
				!Reset module and open all relays
				!Closes relay 002 (connects
	DIAG:CLOS	0		!CH002 to relay 003 in bank 00)
				!Returns 0,1,0
DIAGnostic:OPEN

	DIAGnostic:OPEN <relay>{,<relay>...} opens individual relays on the
	E1470A. Since these are Form C relays, “open” means the relay is
	“reset” to its power-on state (COMMON to NC).
