Agilent Technologies 87130A manual Example Command

Remote Operation

:OPEN

	It is possible to combine OPEN and CLOSE in a single command since they are
	both part of the ROUTe subsystem. For example:
	ROUTE:CLOSE (@406:410);OPEN (@202);
	This command will close channels 6 through 10 on card 4 and open
	channel 2 on card 2.
Example Command	ROUTE:OPEN ATTEN_14;
	Sending the above command causes the set of switch OPENs and CLOSEs
	defined by the PATH with name ATTEN_14 to be executed. The first group
	of switch settings in the PATH is interpreted as OPEN settings and the
	second group as CLOSE settings.
	The CLOSE settings are all executed first, followed by the OPEN settings.
	For example, if ATTEN had been defined as:
	ROUTE:PATH:DEF ATTEN_14,(@101,102),(@103,104);
	then when that path is sent by ROUTE:OPEN ATTEN_14, switches 103 and
	104 will first be closed and then switches 101 and 102 will be opened.
NOTE	If you are configuring hardware for switching systems, keep in mind that
	CLOSE settings are executed before OPEN settings when a path is sent.
	For example, multistage attenuators should be set up so that a CLOSE
	operation always adds attenuation and an OPEN operation removes
	attenuation. This ensures that in moving from one attenuation setting to
	another, the intermediate stage (after the CLOSEs and before the OPENs) is
	a stage representing higher attenuation, and thus avoids signal spikes that
	could damage sensitive hardware.
Example Command	ROUTE:PFAil:OPEN (@101,2(0:5),3(1,3,5));
	The ROUTe:PFAil:OPEN command lists the channels desired to be opened on
	power up or after *RST or *TST?. The channel list has the same restrictions as
	those for the ROUTe:OPEN command. Sending the command in the example
	above causes channel 1 on card 1, channels 0 through 5 on card 2, and
	channels 1, 3 and 5 on card 3 to be opened on power up.
	ROUTE:PFAil:OPEN ATTEN_14;
	Sending the above command causes the set of switch OPENs and CLOSEs
	defined by the PATH with name ATTEN_14 to be added to the PFAIL list.
	The first group of switch settings in the PATH is interpreted as OPEN
	settings and the second group as CLOSE settings.
