Thumbs up M3 Semiconductor Analyzer - Cool kit for device matching

Howdy,

Has anyone seen or used this: http://www.m3electronix.com/sa.html

I just finished building mine this weekend and it's pretty darned cool. Sure, it's not mega-accurate or "audiophile" approved (audiophile as in: fear of microdiodes, can hear a socketed op-amp, $4,000 speaker cables, etc.), but I'm impressed.

I wanted to match some small-signal devices for a discrete op-amp/preamp design and was going to build a jig and build my own. I figured I'd do some research and see what was out there and get some ideas. I came across the M3 and got one. I really like it and built mine with an AC power supply and transistor sockets along with a small PCB for SMT devices to speed testing. I attached a picture.

I'm not associated with the company in any way, but thought it was a great product and pretty cheap (about $67 total with a case and S/H) for everything it did and thought I'd spread the word for other DIY'ers.

Enjoy,
Paul

Some multimeters have a built in transistor gain function. Of course this only works for matching known transistors. I have a leader curve tracer set up with a dedicated 3" scope. I like seeing the waveforms but a device like the one mentioned here that gives a readout sure is nice.

I have a cheap Multimeter with the transistor function. i have used it for some small transistors but i have no idea how accurate that thing is or what exactly it is measuring even though it says beta. I need a better system and this looks quite nice for a small device to at least get some basics! I like the fact that the leads can be hooked up in any fashion and it figures out how the DUT is connected! thats cool!

My kit arrived in 3 days and i had it built in about 1-1/2hrs or so with a few breaks and interuptions in there.

Very very cool little kit! I highly recoomend this kit to anyone! Great for basic test's matching diodes, checking out LED's etc etc.

A+++
