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.
NOTE
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 Series 3700A Reference Manual, "Using the web interface"
section, and the "Advanced triggering" topic for other options.
Time:
When selected, you can select options that define when the scan starts and at what rate
triggers will occur.
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.
You can also select select the trigger to use to take a measurement for each scan step.
Immediate
: When immediate is selected, the measurement is taken as soon as the channel is
closed. This is the default setting.
Digital Input
: When selected, you select a digital line (1 to 14) that triggers the instrument to take a
measurement. 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 after the channel is closed and before the
measurement is taken.
