Getting Started
This screen displays the 4 Aux Input readings
along with the 4 lock-in data channels. The Aux
Inputs are always scaled to 10 V.
The Aux Inputs can read 4 analog voltages.
These inputs are useful for monitoring and
measuring other parameters in an experiment,
such as pressure, temperature, position, etc.
We'll use Aux Out 1 to provide an analog
voltage to measure.
Aux In 1 should now read 5.000 V.
The Aux Inputs can be assigned to a data
channel and graphed on the strip chart
alongside lock-in outputs. Use the [Config] key
to change a data channel.
