If there is a solid rod in there, it's probably removable by loosening set screws, such as on a knob or shaft coupler.? You just have to get in there to do it. Bob

The readout characters on my early 2710 display are correctly placed on the screen but each character is a filled green box. Everything else, including menu instructions/operations, works. Is there a

Isn't there a groove on that rod that drops into a notch in the switch actuator? I think it should just pop out of the notch. -ls- "nixxonnor" <nicolaifusdahl@...> wrote:

These knobs seem to have a solid metal rod going from the black knob on the front panel (hindering panel removal), through the front panel and back to the inside switch that is actuated by the

I am not familiar with that unit but in some cases the buttons need to be removed from behind or, rather, the panel must be removed because the buttons have a larger size behind the panel. Bob

Hi! This is my first post. I have read a couple of 100 posts here, and I must say that I am impressed by the commitment of the members of this group. I have just figured out one thing that was

oh well ... it's all on the schematic. On TDS754A the address space 0x04000000L to 0x040FFFFFL is DS1486 and 0x0407FFFFL to 0x040FFFFFL is NVRAM DS1650/DS1250.

a single line of text like /* don't change the next 2 lines, 29,0x7E is special hard-wired debug address */ would make the difference and save your time, anyway. Regards the "NVRAM" backup, in

got it, it seems to be Agilent 488 mode issue. Not sure if it's only issue on my computer, with my adapter, with my drivers or a general issue. However, i've compiled for MSDOS and PCII/A adapter

Hello, Oh FFS, what is so difficult about following these instructions? I have got all kind of correspondence where people have tried to "fix" the code provided by letting their scopes boot up

Hi Jürgen, indeed, with unchanged code it seems to work, for me at least partialy. The address increments properly but the data seems to stay unchanged, after each every 0x400 again the same buffer.

Dennis & John..thanks for this interesting point about Tek "soul"..I have a SC502 & SC504 recently brought & I calibrated to a 0,3% in vert & Horizontal, with fine and crisp trace, and I wonder

It worked, i tested it with the 1S1 that was in there. And then I see the sawtooth and 1S1 signal at the same time. By not using the chop knob but on of the order ( can not remember, the sawtooth

That's a pretty good deal at $25. Hope one of our 465 owners grabs it up. Tom

Hi, I had exactly the same experience with my TDS684a, however, I finally understood what happened and succeeded to backup my RAM & ROM: In the unprotected mode, my scope doesn't boot either,

Hello, My 7904 just died on me. Magic smoke all over and the transformer in the SMPS caught fire. Any chance, somebody got a replacement transformer for me? Preferable in the EU, but US would be

hmm, my first reply was not posted properly, so let's try again. I've tested your code on TDS754A (fw 4.1e), unfortunately it didn't worked for me. First of all, when the S1002 is in

btw, where you found the "m" command ?
