Any non 7K plugins? You wouldn't happen to have a 3T2? My 3S2 is lonely...... Cheers.... [TekScopes] <TekScopes@...> wrote:

A cheap USB oscilloscope will work to check ripple however so will a voltmeter set to AC mode. What sweep IC are you referring to?

Hey y'all, so I'm starting to play around with this. It's trivial to expose IO ports at dosemu, and the NI-PCIIA card is documented to pieces < www.ni.com/pdf/manuals/320045.pdf>. There's even a whole

Someone at Tek had a sense of humour; the photo clearly indicates the scope is dead: x_x (think cartoon characters with x'd out eyes)

Hello TEK 1502 experts. The slow ramp does not seem to function.With the logic boar connected?there is a slow trace on switch on, as though the print switch was pressed, which does not repeat/

Cal labs are pretty thorough.? My advice for checking voltages is that a new U400 could fail if the circuit has severe problems.? I always check the circuit before installing a new part unless the

Question for the OP.......does your scope have either of the side options? RS232, GPIB? If so disconnect them. The battery backup is on the side option on these so if there is no option installed the

I've only played around with it briefly, but I'm pretty sure both cursors move smoothly. Everything seems to be pointing to U400 but have not checked voltages yet. Previous owner had taken it to a cal

I looked at the 2230 service manual. In section 5 it describes adjusting the store/nonstore registration using a box generator accessible from the diagnostics menu. So the X isn't normally seen or

You are right, it could be U400.? But I would try the other things first, lol.? In Barry's case, he has a source for an alternate U400.? I would try that AFTER?verifying all voltages are in

Two points: Barry's 2465B and mine have very similar issues with non-linearity on ch1 and ch2 but ch3 and ch4 OK. At least on my scope the power rails are ok for voltage and ripple. I also checked the

I made this comment earlier today but somehow it didn't get through, it seems: With these symptoms, I have *only* seen U400 as the culprit during the past 4 or five times this came up on this forum.

This is the reason for my concern about being dropped.? This case is very sturdy, meant to be a portable scope.? I cant imagine how to distort the case with a normal blow.? I have an older rack

Oh well, so much for that. Another possibility is to duplicate 2230 ROMs and try in a 2220. As I mentioned, the purpose of the big X could be to align the storage display with the CRT. The lines

The ROMS in the 2220 are 1603976-04 and 160-3975-04, different to the 2230 and a quick comparison between the boards doesn't appear to have much difference apart from the obvious lack of cursor

Hello all, new to the group and happy to be here. I just wrote a long intro about me and my new Tek 465 into the Yahoo groups 'new post' textbox, but it seems to have vanished ... so I'll briefly

I don't recall exactly how the 2220 was differentiated from the 2230 for product positioning, but I do know the guts are mostly the same. I think the 2220 was reduced in performance by limiting the BW
