SIGVIEW supports data acquisition of analog voltage signals by using LabJack U3 and U6 (LV/HV) device types ( For the support of T-series LabJack devices, see this chapter.

For general concepts and details regarding data acquisition in SIGVIEW, please see the Data acquisition overview. A standard LabJack "Universal driver" is used for data acquisition.

If you choose "LabJack" as a device type, you will be able to set some device-specific options in the following dialog:

For more information about settings, please see LabJack online help at:

Channel mode: Single-ended or differential.

Ref. channel: Used only in differential mode, defines which channel is used as reference level (default is 32 = Vref/ground). These are internal channel indexes (0-based) which are not related to SIGVIEW channel indexes (1-based). See for example and other LabJack resources for details.
