[SI-LIST] Re: Pin Type Scope ground

  I use those also but the 1 Ghz Tek probes I use have a short slip on type 
ground lead (male for the probe side, female for the board). I suppose I could 
make a 1" or so long lead with an alligator clip. I find that the logic 
analyzer style clips pop off too easily.
   
  Obviously I'm assuming the ground loop is very close to the signal of 
interest.
   
  What do you use to attach the ground of the scope to the loop?

  We use surface mount loops.  I can provide a pdf picture if anyone wants
  one.  I'd post it with my reply, but I understand attachments don't get
  forwarded.

  speed scope grounds. I've used the loop style where you use a clip adapter
  but the clip often slips off and of course it increases the size of your
  ground loop. Through hole is not desireable from a layout and manufacturing
  standpoint even though it would be used for proto only.

  would think they might be problematic from a automated assy standpoint but
  that is not a requirement.
