Re: Oscilloscope for Beginners
I used a Tek 465 at my first job, the 475's little brother. And used Tek 2465's most of the 1980's. I like an analog scope, the aliasing on these digital beasts can really throw you. I know exactly

Re: Oscilloscope for Beginners
Hi, Jerry. You don't have to spend $400 on a new or used scope. There is a large following and restoration business on-line for Tek scopes. I have always wanted to get a Tek 475A. And, as noted,

Re: AE7EU Top Level PCB Mod
Sadly, I looked a little closer last night, got a little grumpy. The headers don't line up very well. But, that's what happens when you use calipers and not a drill/gerber file for exact pin

Re: Oscilloscope for Beginners
If you have $400 to burn, by all means get a good scope. Maybe John will loan you the money.? ;-) But that 20mhz $60 USB scope would be a good start. Good enough to work on a Bitx40, though the 45mhz

Re: Oscilloscope for Beginners
Peter ? I have a Siglent SDS 1202X-E that I got on big sale last year at Dayton/Xenia. I like it a lot. I've used the FFT function as a spectrum analyzer as often as looking a signal vs time traces.

Re: Oscilloscope for Beginners
For RF use, I should think the absolute minimum bandwidth would be 60 MHz, 100 or 200 MHz is much better. The 20 MHz scope is used mainly in audio work -- it is not very useful for RF. The

Re: Oscilloscope for Beginners
It's only 20Mhz but would have some application.? I have been using one for years in robotics industry and has worked flawlessly for me. Vince N1VIN

Re: Oscilloscope for Beginners
If you don't have a lot of cash, you can go the used route. A decent dual trace 100Mhz scope can be found on eblah for 100 bucks or more. Stick to the name brands like Tektronix or HP. See if the

Anyone have an opinion on the Siglent SDS1202X-E? I’ve been leaning towards that one after shopping for a few weeks. $379 and Amazon Prime will have it to me in a couple days. For the

Re: Oscilloscope for Beginners
Guy, IMHO, you'd be better off with the HantekDSO5202P dual channel 200MHz scope they have for $275. I think shipping is free. I bought one a year ago for $300 and it's great. There are a bunch of
