5.2.1 D/A Output
This test cycles 3 of the analog output channels from 0% to 100% of Full Scale in 20% FS steps.
It starts by outputting 0 volts to all four channels and displaying a 0% button. Then, every five
seconds, the output is increased 20% FS and the button is changed accordingly. Thus, the button
(and the analog outputs) will cycle through the following values:
0%, 20%, 40%, 60%, 80%, 100%, 0%
To pause the output at the current voltage, press the
n%
button. To resume automatic cycling,
press the
n%
button again.
