A
Probing Hi-Speed Signals with
InfiniiMode Using SQiDD as a
Feedthrough
If you need a feed- through that will let you probe Hi- Speed signals with
the N2750A Series InfiniiMode probe, you can use the E2646A/B SQiDD
test fixture (normally used for Full and Low Speed testing) and
InfiniiMode probes.
Use the center section of the board as the feed- though. Probe the signals
using the test points.
