Synchronous analog, digital, and counter sampling

The USB-1602HS-2AO samples all analog, digital, and counter inputs simultaneously, while also generating up

to two analog outputs and digital pattern outputs at the same time.

The maximum analog input sampling rate is 2 MS/s. Digital channels (digital input and counter channels) can

be sampled at rates up to 8 MS/s for one channel when no analog channels are sampled, and rates of up to

2 MS/s when analog channels are also sampled.

Input clock pacing

Analog, digital, and counter inputs can be sampled based on either an internal programmable input pacer or

with an external clock source (XAPCR pin on the SCSI connector or the EXT CLK BNC connector). Analog

channels can be paced from 0. 5 µs to 1000 seconds in 20.83 ns steps. Digital and counter inputs can be paced

from 250 ns to 1 second in 20.83 ns steps.
