Example Command

Remote Operation

:CLOSe

ROUTE:CLOSE ATTEN_14;

 

Sending the above command causes the set of switch OPENs and CLOSEs

 

defined by the PATH (refer to :PATH on page 4-55) with name ATTEN_14 to

 

be executed. The first group of switch settings in the PATH is interpreted as

 

CLOSE settings and the second group as OPEN settings. The ΧΛΟΣΕ settings

 

are all executed first, followed by the OPEN settings.

Example

If ATTEN_14 had been defined as:

 

ROUTE:PATH:DEF ATTEN_14,(@101,102),(@103,104);

 

when that path is sent by ROUTE:CLOSE ATTEN_14, switches 101 and 102

 

will first be closed, and then switches 103 and 104 will be opened.

 

The query form is not available when using a path name, due to the potential

 

for confusion between the first and second groups in the path.

 

 

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:CLOSE (@101,2(0:5),3(1,3,5));

 

The ROUTe:PFAil:CLOSe command lists the channels desired to be closed

 

on power up or after *RST or *TST?. The channel list has the same

 

restrictions as those for the ROUTE:CLOSE 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 closed on power up.

 

ROUTe:PFAil:CLOSE 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 CLOSE settings and

 

the second group as OPEN settings.
