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.
