Locky,
I have the the tracer workinf again, but now I am getting very ragged response and cannot even measure in the same way before. Seems unstable. I replaced both the PMos and the Q7 with alternate transistors. I assumed this was not an issue due to the fact that they are not active in the actual measuring process/ Could this be causing my problems? Also, Although I have never cased it up, shold this help performance, providing a sheild from RF or other interferences?

Q7 and PMOS measurement does not play a role, you can even shorted PMOS D-S. But the protect will disable.


You also can short the Q1 B-E/ Q2 B-E / Q3 B-E /Q4 B-E ,then The LM358 driving the test unit direct. Q1~Q4 not play any role. But you only can measure small signal device.
In this way to see whether the system is stableand.

buzzforb,
Have you tried to connect the oscilloscope to the measured transistor? Possibly occurs RF generation. If so, try to connect 1-10 nF capacitor between B and C or G and S.

I just got one curve tracer.
I am very happy with it....it seems to work wonderfully!

I have one question: Do I need to calibrate the board? I think that once calibration file is sent along with the SW Package.
Does it mean that calibration has been already performed and I don't need to do anything else?
I also was wondering hjow to adjust change scale on the axis it seems to be a little fiddly!

Thank you kasey197!

Locky_z did a good job.....for the next version we want the heater included! At least up to the favorite temperature of Nelson's living room...55 degree Celsius!
Maybe on his birthday it could be some degrees more.....

I agree. You should also test out the script locky wrote to do the MOSFET characteristic curves (you know Id vs Vds at different Vgs) - I think he's posted it either here or on his yahoo user group.

Unfortunately the curve tracer doesn't seem to work very well with Windows 8 but I'm guessing an update will come out eventually that will fix the problem. I love it so I am keeping my win 7 laptop alive to run it )
