Here are some random notes on the expansion options for the
89410A/89441A, for the sake of the archives.

Second Channel
--------------

It's possible to add the second input channel option in the field. An
input channel (either one) consists of a pair of boards, A10 and A21.
The board pairs are identical between channel one and channel two. It's
possible to take a channel one board set from one 89410A/89441A and add
it as a channel two board set in another unit. The firmware will
recalibrate the ADC on the first power-up with the new board set
installed, which takes several minutes.

The only configuration change required to use the second input channel
is a jumper on the A35 source board. Several of the self-tests and the
calibration routine will fail unless you move this jumper. It's a
wider-than-usual black plastic jumper near the connector along one edge.
There are two positions; one position is for a single-channel system
and the other is for a two-channel system. If you add a second channel
and forget to move this jumper, and see the self-test failures, just
power down, extract the A35 module, move the jumper, and start it up
again. It will now work, assuming the added board set is functional.


Memory
------

Options UFG and UTH are nearly identical; both options add more I/O
(an Ethernet port, for one) and additional RAM and take the form of the
topmost board in the backplane that's accessible from the rear of the
instrument. How they differ is in the amount of RAM that they provide;
UFG adds 4MB, while UTH adds 20MB. There's 4MB on the option board, and
a 72-pin SIMM socket that's either empty in the case of option UFG, or
populated with a 16MB SIMM in the case of option UTH.

One can remove an option UFG board and install an option UTH board,
and the system will see it with no configuration changes required. One
can also add a 16MB SIMM to an option UFG board and turn it into an
option UTH board; no configuration changes are required on either the
board or on the system.

It's possible that there's an earlier revision of the option UFG board
that lacks the SIMM socket, but I've not confirmed this.

I've not yet determined what type of SIMMs these boards use, though
they look pretty ordinary. I've also not yet determined if it will take
larger SIMMs.

FWIW, could be old news for many, but I uploaded at ko4bb the required files to enable all software options on a 89410A. The archive is still in the upload area.

I just went and looked at that. I found that same procedure on the
eevblog forum, was that your post? I followed the procedure on my unit
and it worked.

There was one minor issue, though. There's one software option that
this procedure does not enable: AY9, "extend time capture to 1
megasample". My instrument had that option before the procedure, and no
longer does.

It's not critical for me, but I'd like to have it if possible. Do you
know of a way to enable that option as well, in addition to the others?

Send me via private email your original config file with AY9 enabled and I'll try to figure it out. A new checksum needs to be calculated to include this option, in the master config file, plus a few other (binary) changes (options string length, etc...).
?

Wow! Good news!

I was so curious that I verified wich type of memory is used on USG
board : RAM chip was MT4C4001JDJ-6??? (FPM memory type).

Here, I had an old 72 pin memory SIMM of 16Meg EDO RAM Nanya
NT511740B5J-60. Same speed but FPM vs EDO memory type.

After reading several documents, I took a chance and???lucky man, every
thing was OK, UTH option was automatically detected.

I tested option w-cdma without any problem (who need UTH to works
properly).

Maybe it's too soon to know if the long term stability will be OK, but
my 89441A was still OK after 4 hours of utilisation and a few power up.

This is great news! I think it's safe to conclude that it works; it
would likely have failed very early during the memory tests if there
were a basic incompatibility in the memory type.

I wonder if it's possible to add more memory. Somewhere I have some
32MB 72-pin SIMMs, I think they are EDO. Do you have any that you can try?

Unfortunately, I don't have a simm 72 pins more than 16Meg.

Ok. If I can find any of my 32MB ones, I will try it and let you (and
the list) know if it will recognize additional memory.
