bank of channels from the other, effectively removing any parallel adjacent
capacitance from the isolated bank. During a scan, the instrument automatically
controls the bank switches.
If you are not using all of the channels on the multiplexer, divide the input signals
equally between Bank 1 and Bank 2. For example, if you are multiplexing eight
channels using the 16-channel multiplexer, use four channels in the lower bank
and four channels in the upper bank. For even better noise immunity, leave one
unused, grounded channel between each input channel.
