Operation

3.4.4

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.
