 National
Radio Institute (NRI, from whom I took a course many moons ago). Knowing
that if you wait long enough, just about everything shows up on eBay,
I did a quick check and found a few vintage RCA Institutes items, including
an
RCA Institutes Ham Radio Signal Generator Kit.On a whim, I looked on eBay for the 10 MHz oscilloscope kit that came with my NRI course, and there one was, but it had already been built (on left). I remember that the time base was calibrated by clipping a ceramic capacitor to the probe and sticking it in the wall receptacle and adjusting for 16.67 ms. Amplitude calibration was done by measuring a battery voltage with a voltmeter and adjusting accordingly. Close was good enough at the time. See all articles from Popular Electronics.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged. My Hobby Website: AirplanesAndRockets.com
Please Support RF Cafe by purchasing my ridiculously low−priced products, all of which I created.
