The basic converter box is passive and does not communicate back to the carrier. It simply tunes to one of the channels being transmitted together over the wire and re-transmits it to a television or other video device on a standard broadcast frequency (usually a customer-selected, locally unused frequency between VHF 2 and 4).
The test often reveals problems that occurred during assembly, such as defective components, improper component placement, and insulator defects that may cause inadvertent shorting or grounding to chassis, in turn, compromising electrical circuit quality and product safety. [2]
An autoranging digital multimeter can automatically adjust the scaling network so the measurement circuits use the full precision of the A/D converter. In a digital multimeter the signal under test is converted to a voltage and an amplifier with electronically controlled gain preconditions the signal.
A Combination Converter/Descrambler is generally called a Set-top box or STB it is a single (one-piece) system installed in a single cabinet and represents a single component that is capable of descrambling premium services, like HBO or Showtime, pay-per-view cable channels., Video on Demand, Games or other specialty pay services, and ...
A typical modern set-top box, along with its remote control - pictured here a digital terrestrial TV receiver by TEAC. A set-top box (STB), also known as a cable box, receiver, or simply box, and historically television decoder or a converter, [1] is an information appliance device that generally contains a TV tuner input and displays output to a television set, turning the source signal into ...
Any converter box converts the digital signal for the current digital sub-channel to an analog signal (at the reduced screen resolution of the analog standard), outputs that signal onto analog channel 3 or 4 (set by the user to avoid any conflict with local over-the-air channels) and sends that signal to the analog tuner on the TV.

Megohmmeter M1101M. A Megohmmeter or insulation resistance tester, is a special type of ohmmeter used to measure the electrical resistance of insulators. [1] Insulating components, for example cable jackets, must be tested for their insulation strength at the time of commissioning and as part of maintenance of high voltage electrical equipment and installations.
