I would vote for Hewlett Packard HP8510 as the best network analyser of the time and long beyond though. Maybe because I worked for them I am biased, but we were taught to give the competition their due if there was competition.

I think that you made a very good point, Frank, which is another one of the reasons I had for pursuing the development of the spreadsheet, and that is that most people just don't want to tackle LT-Spice, especially at the drop of a hat, or for just one seldom-used app (and most never will). But a fill-in-the-blanks Excel sheet is a whole different story; much easier to imagine using, for the non-Spicy people. And many people already have Excel installed.

P.S. Buggeredness? I didn't know you were into THAT. <grin> See: Google

OK, well, at least it has other meanings, too: Google
I vote for the second on in this context .

Nico, HP8510 sure is a jewel, but, err, would be "slightly" oversized in all regards, for audio-related work, wouldn't it?
Personally, I've been searching for HP3577's which would have been my prime choice, but now I was able to get that SNA-2 for a bargain price that made it very attractive and it does all that I'll ever need...

I see many examples of the HP3577 on Ebay. There is both a model A and B that I see. Is there any reason for one over the other in audio analysis? I see prices from a little over a $1000 to many thousands. I know of a surplus electronics store here in California that should have these units, they buy them in lots and sell fairly cheaply if you know what you are looking for.

Hello,

If I can remember, the B model adds discrete sweeps & limit lines & optional internal instrument Basic to the A model.

Regards.

For the love of an art a man will venture forth.

Now, you can do a mouse-drag on the plot and MEASURE things, like amplitude and time interval. You can zoom-in, first, as much as you want.

A message box pops up, after you release the mouse button, and gives the ymax, ymin, Delta y, xmax, xmin, and Delta X, for the rectangle you made with the mouse, which can be anywhere in the plot area.

It seems quite useful!

I also found the real name of the author of the original plot-zoom code, Jason Vint, and included it in the header, in the code itself.

I also found his zoom-module code for Excel 2000-2003. So I will try posting a special version, for that, a little later, so that maybe the folks with Excel 2003 can have the mouse-zoom capabilities. The 2007 version (v0.992) is attached, in a zipped folder. A screen image is also attached. Notice the new MEASURE button, just above the plot.

Cheers,

Tom
