To see the image associated with a channel pattern, use the
channel.pattern.getimage
command. For example, to see the image of
the pattern, just created called 'one4wire':
print(channel.pattern.getimage('one4wire'))
1001(1031),1911,1922
NOTE
Paired channel are indicated in parentheses in
<ch_list>
queries.
Performing close and open operations on channel
patterns
You can perform the same close and open operations on channel patterns as
you can for individual channels.
To perform a close/open operation on a channel pattern using the front panel
interface, first press the
PATT
key to select the desired pattern. Use the
CLOSE
or
OPEN
key to perform a channel close or DMM close operation. Use the
PATT
key to perform a channel exclusive close or channel exclusive slot close
operation.
To perform a particular operation on a channel pattern, use the appropriate open
or close command with the channel pattern name for the
<ch_list>
parameter. Refer to
Close/open channel operations and commands
(on page 4-
10) for more details.
When you request a close or open operation, the Series 3700 verifies that the
channels exist for a pattern, but does not verify that the switch path connection
is correct. You must ensure the requested operation is safe for a channel pattern
and that a good measurement will result if performing switch with DMM
operations.
WARNING
Careless channel pattern operation could create an electric
shock hazard that could result in severe injury or death.
Improper operation can also cause damage to the
switching modules and external circuitry. Controlling
multiple channels using channel patterns should be
restricted to experienced test engineers who recognize the
dangers associated with multiple channel closures.
