Not as far as I could ever tell. The only advantage was you did not have to set up a kludge to the front of your 'scope.

Kinda depends on what you're doing with it... I have a Huntron Protrack 1 and it does have some handy capabilities depending on what kind of stuff you're working with. (ie, adjustable frequency, source resistance and Clay I've used a Huntron since 1978, 1st one was #596 and find it one of the most valuable test instruments I have ever encountered. Phil Hopkins from APC.... Worked for DEC for 21 years voltage drive to get more detailed images depending on what value components are in the circuit-- plus a computer interface.) I've never really used it much as a repair tool for a single unit, but it's very handy when comparing a 'gold board' signature against multiple production units without the need to power anything on. With a computer attached you can automate things as well. (Better to find a backwards tantalum cap before even powering it up, or even worse-- incorrect parts loaded in an adjustable power supply that'll smoke a bunch of expensive actives if powered. ;-) I did use it to repair on a bunch of GO7 monitor chassis boards a couple years back. I took a 'NOS' board I had to make signatures and then just tested all the 'unknown' boards against the "known good" to find shorted transistors, bad caps, etc. without having to apply power to any of the units under test. One of the external Huntron boxes (I think the current model is the 210?) can be used with something like a Tektronix DSO that has an onscreen pass/fail mask capabilitiy. (So you can make a mask that basically says "any signal inside this boundary is a pass, anything outside is a fail" and you can have less skilled technicians still pass/fail test a board with high confidence and no PC required...) I suppose you could do the same with a paper cutout 'mask' for a less fancy o-scope too. ;-) -Clay _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
