James is correct about the jump in voltage and resistance when going from Low (54 ohms) to Med (about 27K ohms). LOW would be the only usable range in this case. Also, the LOW range open signature shows a 45 degree angle further complicating the analysis. You definitely have a semiconductor in there with low value series resistance (the vertical part of the trace) and higher value parallel resistance (the horizontal part of the trace).

I had a look for data on this IGBT module, but like you couldn't find any.
The Tracker 1000 has a limited range of stimuli, unlike the ProTrack, and later Trackers.
So on low range shows a good "diode knee", but jumping up to the Mid range switches the device hard on so shows what appears as a short, or the Trackers 1000 big jump in voltage on the Mid range cannot show the difference between a low value resistor across a diode or MOSFET switching on.
Perhaps Curtis will confirm or correct my diagnosis!!

I am identifying the internal components from a hybrid power module, BI 72-727-003 (nowhere to find schematics about it) using Huntron Tracker 1000, all pins and its internal components were identified correctly (diodes + power MosFET), except for two isolated pins, they show the following Huntron trace in Low range.   I could only imagine it being generated by two resistor and a diode (50Ω resistor in parallel with a series of diode and 20Ω resistor). This could be the MosFET gate current limiting, the 50Ω for charging and the diode+20Ω for discharging the gate.  In Med scale it shows a short circuit.  I simulated the trace angles with a 100Ω trimpot. Any hint?

James is using a setup similar to the cable testing fixture discussed in this application note on the Huntron web site:

I'd love to know the specifics of the adapter you built, jvthorsley. As well as your findings. I hope you'll include that too in your report.

If you are looking at a Tracker 5100DS on Ebay make sure to contact the seller and verify that it is complete or better yet, ask for pictures with the cover removed.

Unfortunately the analog card for the 5100DS has not been made for many years. The best source would be surplus or eBay. The closest equivalent of a new Tracker would be the 2800S.

 Hello dear

Help: l
Is possible Find analog cards????

- is possible to find for sale Analog PCB; for 5100DS ???

The 5100DS used a GPIB interface so there is not an adapter that I am aware of. You would need to use a USB GPIB interface and old software.
