      What is a Multivibrator?

      A multivibrator is an electronic circuit that rapidly switches because of positive feedback between multiple states. The switch’s output is harmonic. Three types of multivibrator circuits are used in industry today: astable, monostable, and bistaple. Types of Multivibrators The three multivibrator types are: Astable Multivibrator – The circuit is not considered stable in either of

    • LNB Tester

      LNB Tester

      Before you ask what an LNB tester is, you should know what an LNB is. An LNB is the receiving end of a satellite dish. LNB stands for low noise blocker; it is a device that essentially does what it says. It blocks low noise (frequencies) in order to receive higher frequencies in which satellite

    • Round Trip Time

      Round Trip Time

        Round Trip Time, or RTT, also known as “round-trip delay time” is the time it takes for a signal to be sent from a transmitter to a receiver plus the time it takes to verify that the signal has been received; therefore, Round Trip Time is the time it takes for a signal to be

    • Pulse Position Modulation

      Pulse Position Modulation

      Pulse position modulation is a signal modulation technique that allows computers to share data by measuring the time each data packet takes to reach the computer. It is often used in optical communication, such as fiber optics, in which there is little multi-pathway interference. Pulse position modulation exclusively transfers digital signals and cannot be used

    • Baseband

      Baseband

      Generally, a transmission signal contains more than a single frequency. This is to say that there might be several different frequencies linked together or else superimposed on each other. This is just the way all telecommunication systems function. For example, with today's communication technology it is virtually impossible to send low frequencies without experiencing any

    • GMSK (Gaussian Minimum Shift Keying)

      GMSK (Gaussian Minimum Shift Keying)

      MSK (Minimum Shift Keying) is a type of continuous frequency shift modulation that is used to transfer radio signals from satellites and radio broadcasting to mobile devices and vice versa. Unlike other forms of frequency modulation, MSK produces a half sine wave that limits problems associated with non-linear distortion. What is GMSK? GMSK (Gaussian Minimum

    • 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

    • Business Band

      Business Band

      Business band stands for a series of frequencies in the UHF and VHF two-way radio bands, which are exclusively reserved for businesses to communicate within limited ranges. Of course, not just anyone can use this bandwidth. Anyone that wants to use the business band must first receive a license from the Federal Communications Commission, also

    • Medium Earth Orbit

      Medium Earth Orbit

      Medium Earth Orbit (MEO) refers to a satellite which orbits the earth at an altitude below 22,300 miles (geostationary orbit) and above the altitude of Low Earth Orbit (LEO) satellites. Medium Earth Orbit represents a series of tradeoffs between geostationary orbit (GEO) and Low Earth Orbit (LEO). Medium Earth Orbit enables a satellite provider to

    • Radar Jammer

      Radar Jammer

      A radar jammer is a piece of equipment used to scramble nearby radar signals. Radar jammers are often used by drivers to jam the signals coming out from police speed detectors. The radar jammer is very similar to the Power Drainer and is the size of a small box. Radar Jamming as a Crime There
