Hello Jimmy and Magnus. Before I try anything ambitious, I thought that I would attach a picture of 50v part of the low power board with my votage readings written on. Unfortunately, I cannot figure

First I got a couple of junked 2230 storage boards which was how I discovered there are two versions of the storage channel switch in the 2230 and that the 155-0022-00 will oscillate in a 234-0408-20

No, In store mode Pin 6/11 are -2V OK, I had the scope in 2 CH, so that is the channel switching signal. With just CH1 on, pins 2/15 are 2Vdc, 4mV replica of input signal using your differential setup

I just looked at the pictures. Where did you get the 234-0408-20 from? David

Its actually an encapsulated CR1225 with a couple of 1N4148s - I'm replacing it with a small carrier board with a CR1620 (slightly higher capacity) and the diodes. The Renata 125-1 is not made any

Good to know there are two versions. Mine is marked 234-0408B-20. I have inected signal all the way back to the base of Q2105. From there forward seems to work. The Pin 6 of the U2101 not being at

Hi Fred, Just found the Data Sheet of the P93C Probe. It is just a piece of 93R Coax with a length of 30 1/2" and a connector. I shall send a scan. Still searching for the S-30 Delta Standard Manual.

Beware that there are two versions of the 2230 storage channel switch and while they use the same circuit board, there are some discrete parts changes which need to be made if you replace one with the

Thank you for you help! Is that in store mode? Ahh, the settings need to be the same. Settings 1 Khz 1 Volt sinewave, CH1 0.5V Timebase 0.1mS Vert mode: Ch1, XY out, BW in ALT All the storage out

Have you checked the position of all the jumpers on the storage board?, a lot of Ebay scopes come with them in diagnostic position. My U2101 is pt no 234-0408-20 (Later version) Pin 6/11 of U2101

Very nice work, Jose. Any idea what the chips are? Keep up the great work. Tom

I am trying to trouble shoot the missing storage traces. Does anyone have the DC voltage levels for Pin 6 and 11 of a working U2101 (MO36E). I am seeing +5.6 Volts which seems intuitively wrong give

Thanks Guys. I have panels coming on a trade deal. Jerry Massengale jmassen418a@...

Hi Jerry, Why couldn't you use a blank electrical box cover from lowes hardware? Cut to size of course. Chris

Tektronix 2230, identical to 2220, less a few switch options, working, voltage across R907 0.23Volts JC

Anybody knows what is the bandwidth for Wavetek 5809A spectrum analyzer?

to fill/close empty plugin front space maybe i will find the tek part number again got where, i got mine from ebay Peter ===================================== Hi, What are blind panels? Where do you
