Sadly I got no further - and without a CLIP I think there's little hope. I know that a CLIP for the THS7xxA handhelds is out there, but AFAICT nothing of that sort exists for the TDS3000 series. David

One minor correction: Blumlein's cathode-follower patent is dated 1934, when he was working on television. EJP

It can, I've done it. Even did it on an old Tek 4041 controller. I'm currently using a Prologix GPIB-Ethernet controller so I can even use PHP to get the data from a scope, SA, whatever and do a

If you think of an amplifier as a stage, an attenuator at the input [ahead of the gain element] adds directly to the noise figure of that stage. The objective of the exercise is to compare three ways

Maurizio, Could you post a clearer picture of this scope? If possible, could you also post a picture of the rear panel of the scope? This is indeed a mystery, but we must believe the evidence of our

I would assume, Dave, you didn't find anything else to report. I was thinking about this occasionally (I'm also working on a TDS 3000). If the pins you accidentally shorted were some outputs, you can

Hi, if your amplifier is able or not to reduce noise at its input is not related to the amplifiers noise figure. However, the Transfer Function is the one to be used. G?ran

Ah THANK you. Now I see the fuzzy presence of the word “Storage” three buttons. The mystery continues. Roy Roy Morgan K1LKY since 1958 k1lky68@... Western Mass

Pictures of the mysterious 2215A storage: /g/TekScopes/album?id=262340

Scope folks, This is all very mysterious to me. In neither the actual Tek 2215A scope I have here, nor in any of the pictures at https://w140.com/tekwiki/wiki/2215 do I see any button marked

7470.exe does just that. Read the help file, carefully (there's a lot to it.) -- john, KE5FX

Thank you Chuck! I was unaware that J. Willard Gibbs also contributed to electronics, but I am not at all surprised. My educational background is in Materials Science and he is will known as on of the

I had some trouble opening the picture on my phone. Finally got it to open but it was never clear enough to read the fine details, but obvious that it is a storage scope of some sort. That is a very

If you take a look at the picture of the scope in the gallery ( as I wrote ) you can see that the scope has the memory control pusbutton in the front panel I had some trouble opening the picture on my

I have a 2215A myself, and that one is purely analog. I've never seen a 2215A with the addition 'Storage'... My guess: it has an analog storage CRT... Leo

FWIW In the event that you have a system on which the calibrator output is not working, if you connect the "Internal clock output" to an input and set the trigger to "internal" you should get a proper
