    en.wikipedia.org/wiki/Oscilloscope_types

    A PC-based oscilloscope is a type of digital oscilloscope which relies on a standard PC platform for waveform display and instrument control. In general, there are two types of PC-based oscilloscopes Standalone oscilloscopes which contain an internal PC platform (PC mainboard) – common with upper mid-range and high-end oscilloscopes

    en.wikipedia.org/wiki/High-frequency_direction...

    Working with Jock Herd, in 1926 Watt added an amplifier to each of the two arms of the antenna, and sent those signals into the X and Y channels of the oscilloscope. As hoped, the radio signal produced a pattern on the screen that indicated the direction of the strike, and the slow-decay phosphor gave the operator ample time to measure it ...

    A Tektronix 465 portable analog oscilloscope is a typical instrument of the late 1970s. In the 1960s Tektronix introduced the relatively compact 450 series of portable oscilloscopes, starting with the 50 MHz 453. The 453 was superseded by the 454. There was also a 422 15 MHz AC/DC portable made. [1]

    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 ...

    A Pringles cantenna for Wi-Fi. The cylinder portion of the can may consist of metal-coated paperboard.. Although some designs are based on a Pringles potato chips can, this tube is too narrow to increase the 2.4 GHz signal by a useful amount, [1] although at 5 GHz it would be about the right size.

  7. Antenna types - Wikipedia

    en.wikipedia.org/wiki/Antenna_types

    The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...

  8. Oscilloscope - Wikipedia

    en.wikipedia.org/wiki/Oscilloscope

    An oscilloscope, (formerly known as an oscillograph), (informally scope or O-scope) is a type of electronic test instrument that graphically displays varying voltages of one or more signals as a function of time. Their main purpose is capturing information on electrical signals for debugging, analysis, or characterization.

  9. Smart antenna - Wikipedia

    en.wikipedia.org/wiki/Smart_antenna

    Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
