Hi i got one of these new in this UK ( HULL - were I was designed and made ) then brought it to Canada over 25 yrs ago and it still works great in it the only scope i use -- ty for the great videos --
I use ch2 as my main input, as it is fed out the back, which I feed to a frequency counter, so you can view the waveform and measure the frequency at the same time.
Nice score, basically the same as my 2432A, I suggest you go through and replace tantalum caps before they start to blow, I've had a few go in the past year on mine, I did videos of those.
I have a 2430M and I had this happen as well. Specifically is was on the timebase / display board (2.7uF tantalums). Electrolytics look great on the unit I have.
I have the 2430A (150MHz), while it has some limitations when it comes to measuring modulated RF envelopes it's been a great scope and a good backup to my 2465. The "intensity" adjustment sets the trace intensity when using A/B timebase delay.
My 2430L has a soft screen also...there is an adjustment on the left side, facing the front, and about half way down, with the cover off.. You will see it. I was going to make a hole where the adjustment is so I could change it with the cover on...just in case the cover changes things when put back on.
Requires an elevation in heater current and G1 bias. It forces the cathode to shed a layer of coating that is not emitting electrons. It can result in total loss of emissions or a temporary gain.
Thanks for sharing. I just got. One of these ... You're video has helped me plenty..

33 years old...built in 1987. They were some of the first memory scopes out there

Nice buy for the money! I'd love a scope with readout.
It looks like that this Tektronix 2440 is working properly.
Intensity is the graticule backlight.
Actually Intensity is the adjustment for the enhanced A timebase. The Graticule is adjustable too.

I have the little bro to these two...the 2431L...

Can you do a video on how to set up for a cb radio I would really appreciate it
Is there a reset on it

Good idea Kenny. I was thinking of rejuvenating the crt in my DSA but it's risky!
@@SoddingaboutSi How do you rejuvenate a CRT..?

Hi is this touch screen?
No. Far to early for touch screen.
