The '''Tektronix 524''' is an oscilloscope [[introduced in 1953]] for monitoring television waveforms.  It is a monolithic oscilloscope.  It was designed by [[Cliff Moulton]].
The '''Tektronix 524AD''' is a monolithic oscilloscope [[introduced in 1953]] for monitoring television waveforms, designed by [[Cliff Moulton]].


Interestingly, the 524 appears on page 33 of the [http://www.americanradiohistory.com/Archive-Catalogs/RCA-Test-Equip-1966.pdf 1966 RCA Test Equipment Catalog].
In a 1972 interview, [[Charlie Rhodes]] recalled:
<blockquote>
In 1953 Cliff Moulton re-designed the [[514]] for TV station needs. This became the 524, the first TV-oriented instrument. It looked like a market of 200 or so in those days, but wound up producing 10,000 of this model.
