Hi All, I bought a TLA7AA4-CS for $100 and a set of (4x) P6860 cables for $125! Hah! As I've heard it said around here, the cables are how the surplus guys make their burritos! The probes were shipped inside good quality metal zippered anti-static bags, and all had their nut-bars in place, along with a Tektronix (061-4254-00) proper care and feeding of P6860 probe blurb (see photo attachments). It was a sweet deal. Now if I could just use them... So....I'm making an Eagle (v5.5) PCB component library for the P6860 cables, to enable me to fabricate a flying lead adapter board and Mictor adapter board sets. I completed the component library last evening, but in double checking things I noticed the keep-out zone is touching the elastomer-holder 'key'-hole radius. I've checked and double checked the Tektronix mechanical drawing (071-1059-04, pg 72) against the Eagle CAD drawing that I made and its spot on numerically, down to +- .0005mm, but eyeballing the actual part and also using my digital calipers, I did a rough check on the part itself.....there seems to be something wrong with the Tektronix drawing. Unfortunately, CadSoft EAGLE (as far as I have been able to determine), does not import Allgro or Cadence CAD files, else I'd just import it and be done with it. So, anybody out there have an accurate P6860 mechanical drawing from which a useful PCB layout has successfully been made? (that way I know it works) I just need an accurate mechanical drawing. I don't feel like sending out for fab two or three proto-boards while trying to guess things out. @TiN I plugged in your SPI/I2C dll & TSF files per your instructions, and hah! They work great on my new TLA7AA4. I also tried your serial decoders on my new TLA7N4, for which I received error messages. I'm curious how did you know how to trap the internal messages that TLA software uses? Is there a Tek ref book with this type info in it? In any case, I'll study your code and figure things out, thanks for sharing your engineering. Thx in advance bench_knob ps when I get things straightened out, I'll post the P6860 library & adapter sch/boards here in the EEVblog... |

Great price, i paid triple of that for module and two 6860's From ALTERA Stratix III devkit board. --- Quote ---I'm curious how did you know how to trap the internal messages that TLA software uses?

I just polished it for my own system, nothing else. ::) |

Re; SparkFun, "Nick-o", isn't that our Ncto? I seem to recall similar routines on another website posted by nicto? Onward... bench_knob --- End quote --- |

@bench_knob This is exactly what I was planning on making - I got four of those for $30 each. They've arrived, but I'm still waiting on my TLA715... >:( I have spent some time studying the mechanical drawing, and thinking about how to strain-relieve the flying leads without making it too bulky. Anyway, I noticed that you quoted (071-1059-04, pg 72), whereas my 6800 manual is numbered by section i.e. my drawing is on page 2-28, even though the document title is the same as yours. There is no date on it, but if you think it might have different data, let me know and I'll email it to you. EDIT! Duh, I just realized it's page 72 in Foxit Reader... :palm: |

One and the same 8) On my turn I used some basic code provided by a user called 'Schnelle' from the Tektronix forum. All in all some nice teamwork! Edit: regarding fixing flying wires: I'd use the screws to attach a small PCB to act as a strain relief. The gold plated traces come off very easy from ceramic carriers. |
