Note Each command in these subsystems is covered in detail in Chapter 4 - "Command Reference".

Each input parameter setting is unique to each port. The settings are "remembered" so that changes made to one port do not affect the changes made previously to the other port. However, the signal range set (or changed) for one port applies to the other port as well.

Selecting the Input Port The digitizer input channels are numbered 1 and 2. The input ports on each channel are:

channel 1

port 1 - singled-ended input

port 3 - differential input

channel 2

port 2 - single-ended input

port 4 - differential input

The active input port is specified by the (@<input port >) parameter of the CONFigure and MEASure commands, and by [<port >] in the other digitizer commands. In those commands, [<port >] is optional as indicated by the brackets []. If a port number is not specified, port 1 (channel 1) is assumed.

The active input port is also selected with the command:

[SENSe[<chan >]]:FUNCtion "<function >"

The "<function >" settings are:

VOLTage[:DC]1port 1 (channel 1)

VOLTage[:DC]2port 2 (channel 2)

VOLTage[:DC]3port 3 (channel 1)

VOLTage[:DC]4port 4 (channel 2)

Readings are taken on only one input port per channel.
