Digital Trigger IN for Continuous Analog Input
The GPIO can be programmed as the digital trigger source for continu
-
ous analog input acquisition. Please see External Digital Triggering for
details.
3.4.5
Synchronization Sample Clock IN
To synch multiple devices, the GPIO can be programmed as external
sample clock input, with the same trigger signal and external sample
clock applicable to multiple USB-62405s to achieve more than 4 channel
synchronization without phase delay. Note the synchronization sample
clock must be continuous, with valid frequency range from 1 kHz to 128
kHz.
