Product Overview

AM5eXT-200Wideband Transmission Test Set What Is It? The Ameritec Model AM5eXT-200 is a wideband transmission test set. It is specifically engineered for peak performance for use in the field and in the lab. This easy to use unit offers a full range of transmission impairment measurements and a highly versatile signal generator in a single, compact, portable unit. About the size of a telephone directory, this test instrument fits conveniently on a bench top for use as a laboratory unit or can be rack mounted. The user has 100% digital control of all measure, filter, send, and termination functions. It is equipped with dialing capability and by front panel binding posts for a linemans test set. With the addition of an optional rechargeable internal battery pack and soft carrying case, the AM5eXT-200 can be utilized as a field tester with a battery life of up to six hours of uninterrupted use. This unit conforms to ITU standards and is CE approved for use in the European Community. What Does It Do? The Ameritec AM5eXT-200 can perform qualification tests on circuits carrying voice band, high quality audio and Basic Rate ISDN and HDSL or other services using up to 200 kHz bandwidth. It has the ability to simultaneously send signals and measure received signals. Individual selection of "send and receive terminations" and "On Hook/Off Hook DC Hold" circuits are provided. How Does It Work? The technician utilizes the front panel with simple selection keys for all measure, filter, send and termination functions. The front panel is divided into easy to locate and easy to read areas for each of the major instrument functions. The selected configuration can easily be viewed at a glance. All measurements are fully auto ranging and may be viewed on the bright LED display. Designed with a built-in selectable 2.16 uf termination in series with the selected impedance. A built-in speaker allows the operator to audibly monitor either the send or receive. With an operating bandwidth to 200 kHz, the Sweep function can be programmed to automatically perform tests across the 20 kHz to 200 kHz bandwidth, while simultaneously measuring level and frequency across the same bandwidth. What Can It Test? dBm level or dB loss Frequency Frequency Response (Attenuation Distortion) Noise (Wideband or with Filters) Noise with Tone (Wideband or with Filters) Signal/Noise Ratio (Wideband or with Filters) Noise to Ground (Wideband or with Filters) Impulse Noise (Wideband or with Filters) Phase Jitter Amplitude Jitter Micro Interruptions Group Delay Inter-Modulation Distortion (4 tone/2 tone) 2 and 4 Wire Return Loss Transients (including Phase & Gain its, Impulse Noise with Tone & Interruptions) With the use of the Model AM47XT accessory printer you are able to print or plot your results. When connected to the optional RS232 port, the printer can run a hard copy of any test set-up and/or measurement result. When making envelope, group delay or frequency response tests, the "Print Lock" feature may be engaged for an automatic printed record of the test results in both graphic and numeric form. Through its DTMF dialing capability the AM5eXT-200 can command the Ameritec Model AM440 Remote Test Partner¿ to remotely: Open Tip and Ring for foreign voltage sets Ground Tip and Ring for resistance to ground measurements Transmit preset tones from 304Hz to 384kHz, slopes, sweeps Short Tip to Ring to measure loop resistance Quiet Termination for Noise or Impulse Noise Testing Test for Load Coils
