To create a channel pattern from the remote command interface:
You can also work with channel patterns using the following commands:
channel.pattern.catalog() (on page 7-35)
channel.pattern.delete() (on page 7-36)
channel.pattern.getimage() (on page 7-36)
channel.pattern.setimage() (on page 7-37)
channel.pattern.snapshot() (on page 7-39)
Refer to the TSP commands for more details.
Performing close and open operations on channel patterns
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 Close and open channel
operations and commands for detail.
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.
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.
3. Perform any of the following actions:
•
Open the channels in the channel pattern: Press OPEN .
•
Close the channels in the channel pattern without affecting any other channels: Press CLOSE .
•
Close the channels in the channel pattern and open any other closed channels on the instrument:
Select
PATT and select EXCLOSE. Press ENTER to open or close the channels.
•
Close the channels in the channel pattern and open any other closed channels on the slot: Press PATT
and select EXSLOTCLOSE. Press ENTER to open or close the channels.
To close or open the channels in a channel pattern from the web interface:
1. From the list on the left, select a slot with an installed card.
2. Click Pattern . The Channel Pattern Configuration dialog box is displayed.
