Verbatim is correct. Use my listed steps verbatim and it will upgrade. Time on the instrument was close to the time stamp I generated but not exact. I don't think it's important as another user verified he used my same timestamp at a later date. Good luck! |

Although I do have all the linkages, it'll still require some cutting, hacking, solder'n, copying, pasting...and sweating. But frankly it was very rewarding and it works great when run remotely via EtherNet!! I love it now and with the 32 Mb TLA7AA4, its hot! --- End quote --- Thanks, bench_knob! I'm not sure I have the time or energy for a multi-year adventure. But I do know there's much to be learned here. Most of my lab gear from my latest move isn't even unpacked yet, but I just noticed I had a couple TLA-7N3 modules unboxed, one 2S and one 6S, that I can upgrade to 7S versions (200 MHz, 4 MSa), using the techniques described here recently. That will certainly be worth doing. One thing I would definitely like to figure out is how to do the channel stacking I read was possible with these. I.e., let's say 136 channels width was overkill for me (it always has been, on my 7N4 module), and sometimes I could get along fine with only 17 channels wide. That collapses the width by 8x, and pushes the depth up by a corresponding factor, so 4M to 32M sample depth. I never was able to track that one down, but it would come in handy. I think it was described as a "software option", but I never found it. |

AFAIK Tektronix calls it channel grouping. For the TLA7AA you can reduce the number of channels by 4 and get 2Gs/s with a 128M depth. But I don't recall being able to set lower sampling frequencies while grouping the channels. |

First of all: - Thank you very much to everyone who has made this possible :-+ The short version: Last night I upgraded my TLA7AA2 from 120MHz state / 32M depth to 450MHz state / 32M depth. Today I upgraded my TLA7AA4 from 450MHz state / 8M depth to 450MHz state / 32M depth. Terrific, worked as advertised, what more can you want? Now the longer version: When upgrading the TLA7AA2 I did everything absolutely exactly as in KK's post. All upper-case where he had it, and I included those silly Set/Save Parameter and Code: lines, etc. And, as I said, it all worked perfectly. But come this morning and those 'useless' lines were still annoying my subconcious, so I decided to have a quick look through the TLA7AAx firmware for any strings that looked like they might be associated. The bottom line is that there is a lot of stuff to look through, and I haven't yet made any connections, but in my perusals I noticed that there were virtually no all-upper-case symbols/table-entries etc. The password is there with its mixed case, but that was it. So I decided to try upgrading the second module with just lower-case command entries, and to also only enter the values that needed to be updated. In this case, the only change that needed to be made to the module was to increase the sample depth to 32M, so after establishing communication (remotely) using the Talker/Listener app, all I entered was syst:pass:inst:pass "PitBull5.0.002" syst:conf:depth 33554432 syst:pass:inst:upd 1404025200 and that was it. So now I have 204 channels of nice high-speed capture. I hope I don't need it all to fix this $@#&*! Intel 8039 in my 3468A :palm: I think there's an option for Ida Pro to look at Wind River stuff (can anyone confirm?) It might be interesting to have a bit of a dig through the code. And, of course, I could have the TLA get all incestuous with itself and capture what the 68360 is doing... ;D Ahhh...I just noticed an earlier post by dxl --- Quote ---I dissassembled the Firmware in 2009 to upgrade the Module. --- End quote --- @dxl - Did you use Ida, or some other 68000 dis-assembler? How far did you get into it? Sailor |

Sailor --- End quote --- Most likely the only string that is case sensitive is the password string, "PITBULL" on the TLA7Lx and TLA7Mx and "PitBull" on the newer analyzer modules, and all command strings comparisons are case insensitive. If you dump the strings from the firmware the command text strings are all in mixed case, in the usual convention where the upper case part is the abbreviated version of the string and the lower case part is the remainder of the full length string, and text inside square brackets is an optional qualifier. I wonder how the channel qualifier would be used with depth and speed and not apply to all channels at the same time? :SYSTem:CONFig[:CHANnel]:DEPTh :SYSTem:CONFig[:CHANnel]:SPEed For the curious attached is the command string text dumped from version 5.0.002 of the TLA7Axx firmware. (The TLA7Axx.lod firmware file is a Motorola S-record file which can be converted to binary and then searched for strings). It would be interesting to sniff the VXI bus and observe how these commands are used during the operation of the analyzer. |
