Remote Operation
:CLOSe
Example Command 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.
