Turn your Rigol DS1052E Oscilloscope into a 100MHz DS1102E

I can't think of much. Maybe clean X-Y plots; the digitals are sloppy in X-Y mode.

One scope I wish I had is a Tek 519. This was a real monster, a 1 GHz direct-view scope with a 30KV CRT, distributed deflection, and a tiny, roughly 1x2 cm screen, intended for single-shot photography of transient events. It had no vertical amp and ran about 2 volts/div, where a div was like 1 mm. I do have a CRT and the manual. The horizontal circuit is wild... it uses a 4CX250 in the sweep generator.

I have some pics if anybody's interested.

Didn't Dave say in his blog something about gaussian responses?

When I am looking at video signals with higher power RF signals on the board I will take an analog scope any day.

The advantages of single-shot acquisition, measurement cursors, long-range pre/post-trigger storage, stored waveform pan and zoom, waveform saving, signal averaging, variable/infinite persistance, color, and shoebox size are overwhelming.

For HV/RF stuff, the TPS isolated-input scopes are radical. Clip your scope ground lead anywhere.

Sure, in most cases I prefer a digital scope. When they made the digital scope user interface to mimic analog scopes interface (Why did that take like 15 years???) digital scopes are almost always better. But for the stuff available to me , I like analog scopes in the case mentioned above. I do not often come across that case. Sometimes when I am trying to get a qualitative feel for thermal noise in a receiver I prefer an analog scope too.

I have not tried the TPS isolated input scopes. I hope to get a chance to try one sometime (per your suggestion) , but our capital budgets are severely limited these days.

The Iwatsu SS-7847A is a very good oscilloscope and less old than the

I agree, for video an analog scope is great. In fact the *ONLY* reason for digital is storage, and even then good analog storage scope once existed. Storage is important when you look at one time events, long data sequences, or events with a very low duty cycle that on an analog scope would show with a too low intensity. Those are, as far as I know, The ONLY advantages of digitising. Maybe the FFT thing, and some other processing of data can be added as advantage but that is actually no longer a scope. Larking is a scope buyer, he seems to just buy and buy scopes, not a real scope wizard. I have re-scaled him to 3 on a 0-10 scale.

I can think of a particular aspect of digital storage that, AFAIK, analog storage can't do. With digital storage, one can examine the signal BEFORE the trigger point. Has there ever been an analog storage scope that could do that?

Yes, delay line.

This one is very nifty, but looking at the block diagram in the downloadable "technology" pdf file, it appears that the only way to watch more than one channel at a time is in alternate or chopped mode. Also, unlike digital storage, one can't look at events before the trigger point.

Censorship is a concept that is measured in degrees, not black and white. To summarize your position by stating that you are completely against it , demonstrates that you have not really given much thought to the topic.

You are both ignorant AND stupid. Censorship IS black and white, my ignorant AND stupid friend. I have given far more thought to the topic than you have, for many years, you seem to be wet behind the ears, a young fool who has no experience of what censorship really means. You cannot allow ANY government to control the access to information. To do so is to give up your rights, Australia may be going down the same path that will result in Sharia Law if your ideas prevail. The thin edge of the wedge.

Speaking of which, have you looked in a mirror lately, Mr. Pot?

Ignorance personified.

Really? You think everyone's personal information should be freely available?

When the low end digital scope aliases like hell.

Aren't you the one who showed a scope aliasing a signal such that it reversed time, a couple of years back?

Sure. Have you ever heard of delay lines? Also, delaying timebases were commonly used to look "before" the trigger event. There are applications where I'd still like a calibrated delayed timebase.
