Clear the scan list from the web interface
Clearing the scan list deletes all channels and channel patterns from the scan list.
To clear the scan list from the web interface:
1. From the left navigation area of the web interface home page, select
Scan Builder
.
2. Click
Scan Clear
.
Set up simple triggers
You can set up triggers to control your scan using the options on the Simple Trigger tab. You can set:
•
The event that starts the scan
•
The time interval event that controls the channel action for each step of the scan
To see these options, click the
Simple Trigger
tab from the top of the Scan Builder page.
Selecting triggers
You can choose the triggers that will be used to start the scan. The options to start the scan are:
Immediate
: When Immediate is selected, the scan starts as soon as you click
Execute Background
on the Build & Run tab. Select Immediate when you do not have trigger requirements that must be
met before the scan starts. This is the default selection.
Digital Input
: When selected, you select the digital line (1 to 14) that is used to start a scan. You can
select falling or rising for the digital input. Falling selects the falling edge trigger. Rising selects the
rising edge of the trigger.
If Other is displayed in the mode list, a different mode (other than falling or rising) is already selected.
Other is not a mode and cannot be selected. It is only an indicator that the digital triggering is already
set up for a different mode. See the Models 707B and 708B Reference Manual, "Using the web
interface" section, and the "Advanced triggering" topic for other options.
You can select the trigger to use to continue channel action for each scan. The options to continue
channel action are:
Immediate
: When immediate is selected, the scan immediately steps to the next channel in the scan
list. This is the default setting.
Digital Input
: When selected, you select a digital line (1 to 14) that is used to trigger the instrument to
step to the next channel. You can select falling or rising for the digital input. Falling selects the falling
edge trigger. Rising selects the rising edge of the trigger.
Every N seconds
: This parameter adds a fixed delay between each channel. The delay occurs
before the next channel in the scan list is closed.
