The Tektronix 2247A

Just a little bit about Tek's 2247A scope and some of it's features.

The flickering you see on the scope screen
and the lighted buttons are from the vertical
sync rate from the camera and the scopes
front panel scan rate interference. You don't
see that in real life.

I just bought one. I have digital scopes but I have wanted an analogue for quite some time and the price was right on this guy.

I've had one since the late 80s. It's been very useful and reliable. I actually prefer it over my Tek TBS2000.

One of the Tek engineers told me the co-processor is the same board, same spec. as used in the 400MHz portables and its actually good to about 500MHz. In actual use, I find that it may be true.

[@blunite545]

I think you are talking about the 2400 series that can go up to 400mhz, and most of the boards are interchangeable. The 2200 series only goes up to 100mhz. The 2400 and 2200 series of scopes are
totally different and are not interchangeable.

Nice sharp CRT. Low hour unit.

Yes it's in like new condition, it's backup battery is 3.6 vdc. I think it was from a University or something as the guy
who sold it to me had many. The Tek 2440 i got is also mint but had both the NvRams dead. Easy to fix and cal.
It no doubt has low hrs because both NvRams were dead which means it sat in the off position a lot and it has
one hell of a bright trace as well. Cheers! Love your videos btw!

Hey there! I would love a Tek 2247A however I'll need to be waiting a bit considering how expensive they go for on Ebay. Very amazing features.

[@blunite545]

Wow you are right! There are very few of them and they are expensive!! The 2247A is an analog scope
but has has many features only seen in a digital scope, just no storage. I hope you find one. Check craigslist as well.
