Triggering
Triggering with an Analog Source
Some X Series devices can generate a trigger on an analog signal. To find your device triggering
options, refer to the device specifications.
Figure 11-2 shows the analog trigger circuit on MIO X Series devices.

MIO X Series Device Analog Trigger Circuit
Figure 11-3 shows the analog trigger circuit on Simultaneous MIO X Series devices.

Simultaneous MIO X Series Device Analog Trigger Circuitry
You must specify a source and an analog trigger type. The source can be either an APFI <0,1>
terminal or an analog input channel.
APFI <0,1> Terminals
When you use either APFI <0,1> terminal as an analog trigger, you should drive the terminal
with a low impedance signal source (less than 1 k
Ω
source impedance). If APFI <0,1> are left
unconnected, they are susceptible to crosstalk from adjacent terminals, which can cause false
triggering. Note that the APFI <0,1> terminals can also be used for other functions such as the
