I have at least a dozen books on algorithms by different authors. There's a significant amount of overlap in the specific algorithms they cover, but different authors explain things very differently, and I find that I gain a more thorough understanding when I read similar material written in different ways or from different points of view. Of course the downside is a library of 1300+ books, but really, I don't have any problem with that. :) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Thanks - and I probably will. You might be interested in reading up on the advent of FM radio - "They" said it wouldn't work.

The sentence that Matt quoted from the book seems to support my contention. Dunsmore says it is used informally. I don't see why the reviewer was criticizing except for the purpose of being pompous.

Frankly, I don't see that S11 statement as an error. While
technically, S11 is the measured reflection coefficient, it is that
value which is used, along with the system characteristic impedance,
to calculate the device impedance. So when Dunsmore makes that
statement, he is simply jumping over the intermediate calculation
step to point out that S11 gives you Z. In the context of the
discussion, this does not seem to be an error, but rather a bit of
enlightening illumination in case the reader has not yet made that
small leap.

Re: Which Vector network analysis book to buy - help
Yes, proofreading one's own writing is a low-yield process. Your
brain knows what you meant, and so you tend to see that, rather than
what's actually printed. You need to have other humans look at it,
preferably ones that are generally familiar with the subject, but
not so familiar that they, too, would know what was meant, rather
than what's on the page.
And even then, errors leak through the sieve. Filters have finite
stopband attenuation.

Subject: [HP-Agilent-Keysight-equipment] Replacement OCXO board for 5315B
Hello everyone,
Just as a follow-up for the other topic (1820-2131 for the 5315B counter).
My 5315B came with Option 004, which is the high-stability OCXO. Unfortunately, the Ovenaire 85-50 oscillator had a problem with the heater which stayed cold, so it "worked" and generated a sinewave, but was 30 Hz away from its nominal 10.0000 MHz.
I decided to use another OCXO and got a Bliley NVG47A, for which I designed a PC board which mounts on the original bracket intended for the Ovenaire oscillator (re: attached pictures). No electrical or mechanical changes to the counter are needed.
I have a few bare PC boards which I'd be glad to sell for $1 each plus the price of mailing from France. If anybody is interested, please let me know !
Cheers,
Joel
