IFR WRITTEN TEST

Communications Service Monitor (IFR)

It can be used to verify conformance to the interoperability, coverage, and performance requirements of radio communications standards.

VHF Radio Transceiver

It is a device that is composed of a transmitter and receiver that operates between 30 MHz to 300 MHz. Provides radio communications in the VHF range.

Power Head / RF Interface

It is responsible for converting the incident RF or microwave power to an equivalent voltage which can be processed by the power meter of the Communications Service Monitor (IFR). It samples the RF power for power measurements.

Power Supply

A power source that provides power output to the device and equipment to operate.

Audio Interface

These are ports and connectors needed to connect and send the audio signals from radio equipment to communications service monitor (IFR) and vice versa.

RF Cables

These are type of coaxial cable used to send radio frequency signals. This is where the signal travels.

VHF Through line Power meter

A power meter measuring device designed to measure output power of radios for VHF radio signals.

Dummy Load

It is a device used to simulate an electrical load, usually for testing purposes. In radio a dummy antenna is connected to the output of a radio transmitter and electrically simulates an antenna, to allow the transmitter to be adjusted and tested without radiating radio waves.
