New instrument tracks down PIM problems in TETRA infrastructure(M2 PressWIRE Via Acquire Media NewsEdge) The latest addition to AWT Global's range of PIM analysers, the S1L TETRA MK2, has been designed for testing antennas, cables and components to enable sources of PIM (passive intermodulation) distortion to be located and eliminated from the TETRA network infrastructure. As TETRA radio technology is widely used for communications in the emergency services, lives could literally be at risk if delays are caused by network performance issues such as low data-transmission rates, signal degradation or dropped calls, all of which can result from PIM distortion. Available in the UK from Link Microtek, the new instrument comes in three standard models covering different frequency bands around 400MHz. It offers a variety of test modes for different tasks, including field measurement mode, analyser, multi PIM display, Rx sweep, PIM vs time, and single-carrier mode for insertion-loss and coverage measurements. The S1L TETRA MK2 achieves a high PIM sensitivity of -165dBc, a low receiver noise level of -132dBm and a wide dynamic range of 96dB. The two measurement signals' fully adjustable output power range of 16 to 44dB ensures that testing is carried out in compliance with the IEC 62037 international standard. Test results can be stored in PDF, BMP screen-shot or CSV file formats. Equally at home in the field and in the test laboratory, the PIM analyser features a robust enclosure with 10.2in. touch-screen display, as well as an RF test port, an Ethernet port and three USB ports for input devices or external data storage. The unit has an operating temperature range of 0 to 45degC. An optional embedded module provides functionality for DTP (distance to PIM), DTF (distance to fault), return loss and VSWR measurements, and the wide range of available accessories includes low-PIM cables and adapters, PIM loads and a PIM generator for quick system tests.
