  • Fourier Theory & Practice, Part II: Practice
    Fourier Theory & Practice, Part II: Practice Operating the HP 54600 Series Scope with Measurement/Storage Module By: Robert Witte Hewlett-Packard Co. Practice Adding the Measurement/ Storage module to the scope adds additional waveform math capability, including FFT. These functions appear in the softkey menu under the ± (math) key. There are two math functions available, F1 and F2. The FFT function is available on Function F2. Function F2 can use function F1 as an operand, allowing an FFT to be performed on the result of F1. By setting function F1 to Channel 1 - Channel 2, and setting F2 to the FFT of F1, the FFT of a differential measurement can be obtained. The Measure- ment/Storage Module operating manual provides a more detailed discussion of these math functions. The scope can display the time domain waveform and the frequency domain spectrum simultaneously or individually. Normally, the sample points are not connected. For best frequency domain display, the sample points should be connected with lines (vectors). This can be accomplished by turning off all (time domain) channels and turning on only the FFT function. Alternatively, the Vectors On/Off softkey (on the Display menu) can be turned On and the STOP key pressed. Either of these actions allow the frequency domain samples to be connected by vectors which causes the display to appear more like a spectrum analyzer. The vertical axis of the FFT display is logarithmic, displayed in dBV (decibels relative to 1 Volt RMS). dB V = 20 log (VRMS) Thus, a 1 Volt RMS sinewave (2.8 Volts peak-to-peak) will read 0 dBV on the FFT display.

    NTSC is the analog television system in use in the United States and in many other countries, including most of the Americas and some parts of East Asia It is named for the National Television System(s) Committee, the industry-wide standardization body that created it. History The National Television Systems Committee was established in 1940 by the Quick Facts about: Federal Communications Commission An independent governmeent agency that regulates interstate and international communications by radio and television and wire and cable and satelliteFederal Communications Commission to resolve the conflicts which had arisen between companies over the introduction of a nationwide analog television system in the U.S. The committee in March 1941 issued a technical standard for Quick Facts about: black and white A black-and-white photograph or slideblack and white television. In January 1950 the committee was reconstituted, this time to decide about color television, and in March 1953 it unanimously approved what is now called simply the NTSC color television standard. The updated standard retained full backwards compatibility with older black and white television sets. The standard has since been adopted by many other countries, for example most of Quick Facts about: the Americas North and South Americathe Americas and Quick Facts about: Japan A constitutional monarchy occupying the Japanese Archipelago; a world leader in electronics and automobile manufacture and ship buildingJapan.
