My HP 53310A resumed normal by itself when measuring a modulated signal yesterday.
it detected the extended memory and passed POST.
hope same issue won't come back again!

Re: Keypad for 70820A module
Could please someone confirm/deny whether HP-HIL keyboards from HP 9000 series workstations work with 70000 series? [Y/N]
http://www.hpmuseum.net/display_item.php?hw=575
I have a few HP9000 workstation with keyboard and 70000 mainframe but I only use it with phase noise test set.? I don't have a module to try the keyboard in.
Cheers

Re: Keypad for 70820A module
Sorry guys! The 70820A is a 40GHz MTA (oscilloscope). To do the front panel calibration. You will need 2 ea. phase matched short length 2.4mm cables, the 11667C splitter and 2 ea. 3.5mm-f to 2.4mm-m adapters, and a listed generator. (It is very important that these adapters be identical. You will not pass the phase match self test if they are not the same.)
I had been told in the past it is possible to add a new generator to the list if you can add in all of the required specs and test data into the 70820A ETE Test list. I believe the calibration manual tells you how to do this, but may not list all of the test data required.

No, I couldn't remember what the official spec was, but it was somewhere up
there. The point was that you need the higher grade cables and connectors to
attain full performance, but lesser ones are OK for lesser needs.
BTW this brings up an interesting question. Just how high can a sampling scope
go, and still be considered to "work?" With an analog scope you can
spec the 3 dB bandwidth or risetime, and expect it to roll off gradually above,
but it's still usable for some things, until too much detail is lost, the
amplitude level is too low to interpret, or the triggering craps out. With a
sampler, I would expect similar behavior, except that at some point aliasing
also starts to show and mess it up even more.
Using a more generous definition of "work," I'd guess that at room
temperature environment, the 70820A would be able to show an
"acceptable" sine wave display up to 50-60 GHz. It would have to be a
sine wave regardless of input wave shape, or it would have to be all
aliased-up.
If anyone can readily look at this, it may be interesting to see what happens
beyond the specs.

Yes I am aware that you don't need the keyboard to control things with
out but it seems easier to do.
And I like to find all the bits is possible.
I will try out the keyboard that I have. There are so few details on

anything on any 70K series instrument.

? Some of the keypad inserts use double-width buttons I think, but all
they are are plungers that press the key mechanisms underneath.
