Description
The unit is designed for field testing and measurement of voice and data for 2 or 4 wire telecommunications transmission circuits. This unit is a full function signal generator able to generate all of the test tones and waveforms needed to perform a variety of standard measurements. It is a telephone set with built-in dial, talk and listen capability with a selection of 600 ohm or 900 ohm termination impedance. This unit fully complies with Bell Standard 41009. The Ameritec Model AM48 can do a variety of measurements. With its built-in dial capability on dial-up networks it can access a distant responder or a second AM48 for centralized 2-wire testing. You can use a single unit with an Ameritec responder for centralized loop back testing. Or, use two sets for a complete end-to-end test of 4-wire data lines. In addition, the AM48 now combined with the new AM440 Remote Test Partner" is able to further enhance your testing capabilities. A single technician can test a circuit with an AM48, AM440 and a multi-meter. The AM48 can transmit to the AM440 and measure its signal and can take noise measurements. The combination of these two measuring instruments allows for DMM testing, including resistance testing and the measurements of both voltage and capacitance.
