For example, if the first channel is -10 to + 10 volts and the second and fifth

channels are 0 to +1 volts, enter

[-10,1,1]

Coupling Vector - Enter a coupling code for each of the channels in the

channel vector. The coupling vector must be the same length as the channel

vector. This driver allows a different coupling for each channel.

The following table is a list of the couplings for this driver and the

corresponding coupling codes.

For example, if the first and second channels are single input and the fifth

channel is a differential input, enter

[0,0,2]

-0.1 to +0.1 -0.1 0 - 0.1 0.1

-0.05 to +0.05 -0.05
