Early high-speed visualisations of electrical voltages were made with an electro-mechanical oscillograph, [2] [3] invented by André Blondel in 1893. These gave valuable insights into high speed voltage changes, but had a frequency response in single kHz, and were superseded by the oscilloscope which used a cathode-ray tube (CRT) as its display element.
Tektronix 7854 oscilloscope with curve tracer and time-domain reflectometer plug-ins. Lower module is a mainframe of the series Tektronix TM500 and has a digital voltmeter, a digital counter, an old WWVB frequency standard receiver with phase comparator, and function generator.
1947 Heathkit ad featuring the 5-inch oscilloscope. Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $335 in 2023) for the DIY kit. [1] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath ...
The series also included some storage scopes: 7613 (variable persistence, $5,025 in 1983), 7623, 7633 (100-MHz BW, $7,765), and 7834 (400-MHz BW, $11,705). The series also wandered into digital oscilloscope territory. The 7854 waveform processing oscilloscope ($13,750 in 1983) could function as both an analog or a digital oscilloscope with GPIB ...
In 1961, Tektronix sold its first (possibly the world's first practical) completely portable oscilloscope, the model 321. This oscilloscope could run on AC line (power mains) or on rechargeable batteries. It also brought the oscilloscope into the transistor age (only a Nuvistor ceramic tube was used for the vertical amp input). A year and a ...
A dual-beam oscilloscope was a type of oscilloscope once used to compare one signal with another. There were two beams produced in a special type of CRT . Unlike an ordinary "dual-trace" oscilloscope (which time-shared a single electron beam, thus losing about 50% of each signal), a dual-beam oscilloscope simultaneously produced two separate ...
It was a popular type used in late 1940s low cost and small table model televisions. The 7JP4 has a 7" diameter round screen which was often partially masked. Unlike later electromagnetically deflected TV tubes, the 7JP4 is electrostatically deflected like an oscilloscope tube.
Dual-beam cathode ray oscilloscope type 322-A, Du Mont Laboratories, early 1950s [4] In 1938, DuMont Labs began manufacturing televisions at a factory in nearby Passaic, New Jersey. [3]: 191 To sell TVs, it began the DuMont Television Network in 1942, one of the earliest TV networks. Later, they manufactured cameras and transmitters for TV.
