Performing close and open operations on channel patterns
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 cards and
external circuitry. The control of multiple channels using channel patterns should be
restricted to experienced test engineers who recognize the dangers associated with multiple
channel closures.
You can close and open channel patterns the same way you do for individual channels.
To perform a particular operation on a channel pattern, use the appropriate open or close command
with the channel pattern name for the
channelList
parameter. Refer to
When you request a close or open operation, the Model 707B or 708B 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 connection will result for your
application with the channel pattern.
To close or open the channels in a channel pattern from the front panel:
1. Press
the
PATT
key to display a channel pattern (you might need to press
DISPLAY
first).
2. Select the channel pattern you want to open or close.
NOTE
Model 707B only: Note that when you select a pattern, on the crosspoint display, the lights for the
channels included in the pattern are dimly lit.
