Analog output

You can connect up to four analog output connections to screw terminals AOUT0 to AOUT3. Refer to Figure 4

and Figure 3 on page 10 for the location of these pins.

Each channel can be software-paced at rates up to 5,000 updates per second (system-dependent), or hardware-

paced at rates up to 1 MS/s.

Each analog output on the USB-1208HS-4AO has a fixed ±10 V output range. The outputs default to 0 V at

power up.

External clock I/O

The USB-1208HS-4AO device provides one external clock input (AICKI) and one external clock output

(

AICKO) for analog inputs, and one external clock input (AOCKI) and one external clock output (AOCKO) for

analog outputs.
