    • What is a BUC?

      What is a BUC?

      A BUC (Block Upconverter) is a device that converts radio signals from a lower frequency to a higher frequency. BUCs are used in satellite uplink transmissions in order to transfer data from a ground based unit to a satellite in orbit that will then be redirected to another ground based unit in separate location. Likewise,

    • C Band

      C Band

      C Band is the original frequency allocation for communications satellites. C-Band uses 3.7-4.2GHz for downlink and 5.925-6.425Ghz for uplink. The lower frequencies that C Band uses perform better under adverse weather conditions than the Ku band or Ka band frequencies. C Band Variants Slight C Band frequency variations are approved for use in various parts

      How to Test a Capacitor

      A capacitor is used to store energy so that it can provide power to any kind of electrical appliance when it is needed. Over time, though, the capacitor does begin to wear out and when this happens, its effectiveness in powering the appliance can diminish. Therefore, conducting a simple test on the capacitor can provide

    • FCC ID

      FCC ID

      FCC ID stands for Federal Communications Commission Identification. An FCC ID is the number found in all computer hardware components. FCC ID numbers, usually found on the circuit boards, are helpful in finding information about the manufacturers of the hardware devices. An FCC ID has 2 elements. The first is a three-character Grantee Code which

    • Degaussing

      Degaussing

      Degaussing is a process of reducing the magnetism of a material by applying an opposite magnetic field. The name is derived from a unit of magnetic flux, the gauss. There are many different uses for degaussing. Cathode Ray Tubes Most televisions and computer monitors that use cathode ray tubes have a degaussing function. The electron

    • Spark-Gap Transmitter

      Spark-Gap Transmitter

      A spark-gap transmitter is a mechanism for producing radio signals. It has been the primary radio transmission device during the early years of radio technology. It was soon superseded by other transmitters due to its discontinuous radio wave production and widely varying frequencies. How a Spark-Grap Transmitter Works A spark gap transmitter is basically composed

    • Crosstalk

      Crosstalk

      Crosstalk is a form of interference caused by signals in nearby conductors. The most common example is hearing an unwanted conversation on the telephone. Crosstalk can also occur in radios, televisions, networking equipment, and even electric guitars. Causes of Crosstalk Crosstalk is caused by coupling, the transfer of electrical energy between conductors. The three main

    • What is a Balun?

      What is a Balun?

      A balun is an electrical transformer that is used to convert electrical signals to and from balanced and unbalanced signals. They are normally used to connect lines that have different levels of impedance and are commonly used in the home for connecting HD and traditional antennas. Baluns are also used throughout industry, although it is

    • What is a Clock Generator?

      What is a Clock Generator?

      A clock generator is a type of circuit that produces a continuous, synchronized electrical signal for timing purposes in a wide variety of devices. Because many high end electronic equipment require that electrical signals and mechanical devices work together in an efficient manner, clock generators are often a necessary component in many devices in order

    • What Does DIN Stand For?

      What Does DIN Stand For?

      DIN stands for ‘Deutsches Institut für Normung’ which means ‘German Institute of Standardization’. DIN develops norms and standards as a service to industry, to the state and to society as a whole. It is a registered non profit organization which has been based in Berlin since 1917. It consists of nearly 1,700 members who include
