TDS3032 Loosing its GPIB Address
My TDS3032 (original version) works fine. When I turn it off, it seems to
retain its settings except it doesn't remember the GPIB address configured
in the I/O Setting. I set it to GPIB Address 2, and it reverts to "1".
Is there a lithium battery in the scope or in the I/O Module (I have the
I/O module with VGA, RS232 and GPIB).
I use the scope with GPIB in a test system.
This isn't a major problem, but rather a nuance.

Does your scope have the latest firmware ?
Is the date & time clock working as expected ?
Sorry, I just saw your reply; thank you!toggle quoted messageShow quoted text
It does not keep the date correctly, but it doesn't not exactly loose it
100% either. It seems to loose about 12 hours per day, or perhaps, the RTC
is not working unless it is powered on.
As far as firmware, I doubt it it is up to date. I don't want to break
what is not broken by updating the firmware and have the update fail half
way through. I don't think it's an issue, because the scope just started
this and I have been using this scope for about 10 months now. I should
update the firmware, at some point, when I buy the backup to this scope. I
do have fresh (as fresh as can be since they haven't been made since about
2012) floppies and several USB-Floppy drives (pure data security; no one
can read them anymore -LOL) that I can use to make the firmware update
Question: Can the firmware be updated through the GPIB? The only way I
know is through the floppy drive.
Please tell me that Dallas DRAM (grrrr) is socketed and not soldered to the
I think I can get Dallas DRAMS from China, but I imagine they are just as
old NOS with dying batteries in them? Can you kindly confirm the I.C. part
Thanks very much, again, for your reply an knowledge!

Not that I know of
All the ones I've seen were soldered to the board
If you mean Tek P/N I have no idea, if you mean the Dallas number, yes it is DS1742W-150
Hello again Hakan,toggle quoted messageShow quoted text
Hey, sorry to revisit this again. I just order one “brand new”, from China,
$38.29/shipping. I am supposed to have it sometime next month (Nov ‘18).
I’ll have to post if I’m successful . It looks like a lot of work to pull
the board out to replace the chip. Hopefully, I don’t break it. In
September, I did buy another used TDS3032, from Alltest, in NJ, for $1500
with a NIST cert, and a six month warranty. It works perfect and matches my
tired one perfectly.
I may just buy that Siglent I was thinking of for about $400/NIST cert to
play with and see if I can get a software work-around for the pulse width
measurement reference levels. It is probably fine for the rest of my data
collection work. It is so good looking and sexy for the price - lol.
