Did you know RCA (Radio Corporation of America) used to manufacture and sell oscilloscopes? The Model 155-C oscilloscope was promoted quite aggressively in the mid 1940s as a breakthrough instrument. A quick Google search shows that not many survived, and they are not particularly sought-after by vintage test equipment collectors. It seems the quality of the metal chassis was not very good, although the electronics get high marks. You can pick one up on eBay occasionally for fairly cheap. Oscilloscope Museum has an example of an RCA 155-C oscilloscope (lots of links on the page to images, manual, etc., but they can be hard to find).

RCA 155-C Oscilloscope Advertisement, October 1945 Radio News - RF CafeThe 155-C - A Versatile Oscilloscope

Wherever a general-purpose oscilloscope is required, the RCA 155-C is the choice. Designed for simple operation, faithful reproduction, accurate comparisons, and quick results, this oscilloscope is fast becoming standard equipment in laboratories and service shops.

The 155-C is different from other 3" oscilloscopes because it includes a built-in light shield, removable graph screen, direct deflector connection, binding jacks (a combination binding-post and pin jack), a 6-volt AC terminal, and an improved-timing axis oscillator.

Completely portable and attractively cased, this instrument is priced within the reach of owners of small shops and laboratories.

About RF Cafe

    Kirt Blattenberger,


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 tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
