This device allows one to measure voltage and up to five current paths. twenty five signals pass from a DB25 male connector through to a DB25 female connector. All of these signals are also brought out to the side so that the voltage/waveforms may be measured.

The signal paths are fully configurable and lines can be excluded, switched around or doubled back. Additionally, up to five signal paths may be run through hall effect current sensor loops allowing current sensing on the selected signals. Current sensing sensitivity can be increased by looping the wire through the sensor more times!

This is an excellent tool for debugging designs, diagnosing problems with equipment or reverse engineering devices and software driver output.
