In the distant past we used Tek 465s (I think) in VHF radar sounding of the Antarctic icecap. The radar return was used to modulate the beam intensity, and the result recorded on slow-moving 35mm film

Absolutely no offense taken. It is a legitimate question. DaveD KC0WJN <christian.eisert@...> wrote:

sorry Dave, I didn't mean to be rude. It may have something to do with my English skills. So no, they fall out because they don't meet the original criterion with the blanking circuit ;). I just

Also, going to the TekWiki site, reading the wiki pages and downloading the manuals for any 'scope in which you are interested and perusing the manuals will give you specific information about those

Thank you both, the 4X5s do not have proper beam blanking via the z input, do they ? Bests Christian Am 30.04.25 um 22:20 schrieb Dave Daniel via groups.io:

I was going to suggest that you also look at Tektronix 465s, 475s and 485s. The 485 has the same -3 dB bandwith of a 2465 (350 MHz) and are a bit easier to

I've successfully used a 465B for output from an Analog Computer. They can be had almost for free, and are very rugged. I would not touch a 2465 esp B for this purpose, unless it was all I

Christian, If you want to get a 2465B that have already had the service and maintenance update done to them and in good condition. ?Contact me offline or electronixtoolbox@... as a have a

Thanks for your comments! :-) So the takeaway is: no matter what, I should plan to recap the PSU. Fair enough — that’s the kind of work I’m used to and can handle. If I understand you

Thanks, I had thought about that too. Unfortunately, the 6XX is hard to find here in Germany — and I’m also tempted by the flexibility of using the scope for other tasks as well. That said, if

You might want to consider something simpler like a Tektronix 604 which is specifically designed for x-y display and has a bit larger screen. Reinhard Metz

Hi all, I'm currently looking for a suitable Tektronix oscilloscope for a specific use case: *Displaying vector graphics in XY mode* from arcade PCBs (Atari Asteroids, Tempest, Space Duel, etc.) –

Hi When I was 16, (74 years ago ) I worked on a US schematic to build a power amplifier, 2 feedback capacitors electrlytics were designed in wrong polarity . connected between the tubes plates ..400

Bobert29, My thought is you need to check the plug connectors on the side of the A2A1 board J121 and J122 as you might be one pin off from connector to board. These plug connectors are not easy to

Have you worked on one of these before? ISTR that there's a misprint on the silk screen showing a supply filter cap in the wrong orientation... I know someone who recapped his 2445B and it didn't

Read the little notes below the table for that sweep speed calibration. There is some compromise required at the highest sweep speeds. Also, what makes you think any substitute for U800 is going to
