Hi everyone!
I am looking for a nice logic probe, and is thinking about this one:
http://se.mouser.com/Search/ProductDetail.aspx?qs=WZYOKEqGBpLLUYwELbGxTA%3d%3d

B&K Precision DP-21

Since I newer owned a logic probe before, I dont know what to look for in the specs...

Any tips?

Skip that one.

Get one with audio capabilities.

You can take a good board... listen to the signals... then go to a bad board and hear the differences - especially between a clean hi/low alternating signal and a dirty one from a bad chip that isn't reaching the proper logic levels.

------- Agree with Post.  All kinds of interesting things are coming up on here lately.  I do agree with raymond.  The logic probes are used in ALL industries.  There are some really "smart' ones available nowdays.  Handy tool when needed. B.

I went to the B&K Precision.com website.
None of their Logic Probes have audio capabilities -
though it wouldn't not be hard to throw in a small piezo speaker inline with the LEDs.  stir the pot / get cooking

I know for a fact the one they sold at Radio Shack (Micronta)  has audio (since I have one). The catalog # is 22-303 but it's not shown on-line. Some stores may still have them though.

Here is one of the RS ones e-bay.
