Maybe not the best opinion on a tek group, but i would say some of the older HP scopes had better tubes, probably more like you'd see on an arcade machine. Tektronix are great as scope, triggering

Christian, If your XY needs are fairly high frequency, be aware that the delay in the X and Y is unequal.? About 50 years ago I had to add relays to a 465 to bypass the vertical delay line in XY mode

After following this discussion somewhat, and considering the application, I'd suggest going toward a relatively simple scope like the 465 already mentioned, or maybe a more modern 2200 series unit.

Hi there, I have fallen heir to a Tektronix 453 scope.? From appearances it appears to be fairly clean and complete - with one exception: The rear cover is missing, which exposes the back end of the

Chris Elmquist <chrise@...> added the photo album 465B pack panel ( /g/TekScopes2/album?id=302162 ) : wanted to show the connectors and labeling on the back panel of a 465B,

Actually, the EAROM on the 2465 does get written on a fairly regular basis to store front panel settings.? Not everything is an absolute physical position that can be read back.? Examples: cursors

I took a photo of the back of my 465B and uploaded to the group Photos section. Shows the Z-axis input and the voltage requirements to control intensity labeled at the connector. Chris

I have a 2465 for 33 years now and it continues to function with no issues. ?It came with the counter/timer option, and later I added the word recognizer and GPIB options. I've never re-capped it,

FWIW, you might want to double check that. 465 has a Z-axis BNC input on the back panel. From page 2-8 of the 465B service manual, EXT Z-AXIS -- Input bnc connector permits the application of

The 2465 has a separate blower, which is hard to service, and will need oil by now. The squirrel cage needs to be removed for safety during service, and most don't know how to remove them without

Generally, an ok idea, but if your "B" has a serial number above 50K abd above, you had best check the surface mount capacitors aluminum electrolytic capacitors on the A5 (CPU) board. The damage

Just to add that I still own and use a 465. Totally bomb-proof! Cost me pennies on Ebay. Sent: 30 April 2025 21:32 To: [email protected] Subject: Re: [TekScopes2] Seeking Advice: Tektronix 2465

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:
