Example 1
channel.setdelay("5001, 5003" , 50e-6)
Sets channels 1 and 3 on slot 5 for a delay
time of 50 µs.
Example 2
channel.setdelay ("slot3", 0)
Sets the channels on slot 3 for 0 delay time.

Usage
channel.setforbidden(channelList)
channelList
A string that lists the channels and analog backplane relays to make forbidden to
close
Details
The channelList parameter indicates the scope of channels affected and may include:
▪ allslots or slotX (where X equals 1 to 6)
▪ Channel ranges or individual channels
▪ Analog backplane relays
This function prevents all items contained in the channel list parameter from closing. It applies the
"forbidden to close" attribute to the specified channels. To remove the "forbidden to close" attribute,
use channel.clearforbidden().
If a channel that is being set to forbidden is used in a channel pattern, the channel pattern is deleted
when the channel or analog backplane relay is set to forbidden. Note that if the channelList
parameter includes a channel pattern, the channel pattern will be deleted when the channels in the
patterns are successfully set to forbidden to close.
The channels or analog backplane relays in the channelList parameter must be installed in the
instrument.
If the scan list contains a channel or analog backplane relay that is forbidden, the scan list is
invalidated.
