Section 5: Switching and scanning

Reset a channel

You can reset a channel to its factory default settings. When you reset a channel:
▪
Any closed channels and analog backplane relays open
▪
The poles of all channels reset to 2-pole operation and paired channels are changed to match
▪
Additional user delay is set to zero
▪
Labels return to default of SCCC or slot, row, column
▪
Analog backplane relays specified by the channel.setbackplane()function are cleared
▪
If the channel is forbidden to close, it is cleared from being forbidden to close
▪
If the channels are used in channel patterns, the channel patterns that contain the channels are deleted.
▪
The DMM configurations of all channels are set to nofunction
Using this function to reset a channel or backplane relay involved in scanning invalidates the existing
scan list. The list has to be recreated before scanning again.
Resetting a channel deletes any channel patterns that contain that channel.
To reset a channel from the front panel:
1. Display a channel.
2. Select the channel you want to reset.
3. Press CHAN.
4. Select RESET.
5. Select SELECTED, ALL, or CANCEL.
6. Press the navigation wheel
To reset all channels on a slot from the web interface:
1. Select the slot that contains channels you want to reset.
2. Click RESET SLOT.
3. All channels on the slot are reset.
To reset a channel from the remote interface:
Send the command channel.reset() (on page 11-84).

Pseudocards

You can perform open, close, and scan operations and configure your system without having an
actual plug-in card installed in your instrument. Using the remote interface, you can assign a
pseudocard to an empty card slot, allowing the instrument to operate as if a plug-in card were
installed.
A pseudocard cannot be configured from the front panel. However, once the remote configuration is
complete, you can use the front panel to use the pseudocard. Press the EXIT key to take the
instrument out of remote mode.
When the instrument is turned off, the pseudocard is no longer assigned to the slot.
