For applications that process I/Q data, such as the I/Q Analyzer or optional applica-
tions, and only if the optional Digital Baseband Interface is available:
Defines triggering of the measurement directly via the LVDS connector. In the selection
list you must specify which general purpose bit (GP0 to GP5) will provide the trigger
data.
Note:
If the Digital I/Q enhanced mode is used, i.e. the connected device supports transfer
rates up to 200 Msps, only the general purpose bits GP0 and GP1 are available as a
Digital I/Q trigger source.
The following table describes the assignment of the general purpose bits to the LVDS
connector pins.
(For details on the LVDS connector, see the R&S FSW I/Q Analyzer User Manual.)
