I'm new here and I'm looking for someone to help me with my Tektronix 2465 DNS (aslo known as 2465 CTS ) I made few videos here: https://www.youtube.com/watch?v=oxZZ7-VjCQ0&t=1s about my sick scope.

I have the same oscilloscope. It is also listed under (at least that is what I found today) as Tektronix 2465CTS (or 2465 CTS) . Mine has some problems, sometimes I loose the text on top and bottom of

Hello Jared and Rick, Before you make an investment in this enterprise you are considering, you may want to go back to the beginning of these posts from 2015. It was categorically stated the the real

Hmmm, If that's the case, I have a crimper and dies for the high quality Canare brand 50ohm BNC. I wonder if it's worth me making a batch of cables to send out for the cost of parts and shipping if

I may be a little late to the game but I posted this question to a Tek expert on Youtube: https://www.youtube.com/user/w2aew This comment/request might be a little out of scope, to calibrate a Tek

Nearly all of the Tektronix products from the 1960's were a marvel of superb designs. I actually prefer the older scopes as long as high bandwidth is not an issue. These old scopes are generally very

John and others, I have a 547 and a 545B that I plan to run for a long time. One of the two late 1A1 plugins I have has low gain in one chancel. Not diagnosed yet. Have had other scopes of that era

In one of your earlier posts you said you had seen spiking behaviour on pin 3 of U1624. This will drive larger spikes from the output pin via Q1614 and C1602 into the protection circuitry and can very

Took up Fred's suggestion and connected -5V to the power supply board. Didn't crank the supply up high - tried 0.2A and then 0.4A current limit. Max draw was 333mA with all combs in and P1560/1570

Actually, nothing wrong with the touch panel, as far as I know it is working. It is a spare I acquired when I bought some other equipment. Thanks all for the help. 73 Bill

Thanks to all that replied on this subject. I've decided to make this Tek 1480C waveform monitor free to anyone in the chicagoland area. The only testing I've done on it is to verify the current draw

614-0727-00 was only used in 11401 11402 used 614-0785-00. CSA803 used 614-0864-00. 11403A used 614-0850-00 which was only used in 11403A. Since this is a complete assy including the front panel maybe

Squeezed in a bit of time to check for shorts to ground on all the -5V points. There's no sign from my previous scope traces and multimeter probing that any of the other supplies are faulty. Long list

Hi Bill, In 11401 it was 614-0727-00/01 A9 Touch Panel Circuit Board Assembly (the IR diodes and sensors are on that board) . I feel quite sure that's the same as in my CSA803. No guarantee for your

Thanks, Dennis! I will keep my eye open for one of those. Sean

Hello Walter, I removed all pushbutton switches from the frontpanel board. I measured them and all are in an open state. I expected some to be stuck in the closed state, which would explain the not

Good history of Wavetek here. https://www.eetimes.com/document.asp?doc_id=1224975# John

If anyone here has the service manual for the 11403A digitizing scope, can you do me a favor and dig up the part number for the faceplate/circuit board that surrounds the display? Much appreciate the

Welcome in the hell of 7854 SMPS repairing GeorgeP! Your contribution is more than welcome! Can you post some relevant images of the signal present at various test points of board A12 and A23 when in
