Manufacturers of wideband data transmission systems used in wireless local area networks must prove compliance with ETSI (European Telecommunications Standards Institute) specifications. For 2.4 GHz systems compliance tests for electromagnetic compatibility (EMC) are specified in document EN 300 328 but new measurement challenges have arisen with the introduction of the new version 1.8.1 which supersedes 1.7.1.
New complex test methods for measuring output power are specified which are significantly different; they include duty cycle, transmitter sequence, transmitter gap and a completely new concept ‘medium utilization’. New measurement instruments are needed to carry out the latest mandatory tests.
ETS-Lindgren's USB RF Power Sensor, model 7002-006, is designed to make these measurements. It covers a frequency range from 9 kHz to 6 GHz, samples at 5 Msamples/sec and features a trigger input/output on the probe for synchronous triggering of multiple EMPower meters for power measurements on MIMO (multiple-input and multiple-output) devices.
The sensor’s USB connector provides easy and direct connection to a PC to enable ETSI 300 328 power measurements to be performed on MIMO devices in conjunction with test software. The software, supplied at no charge, automates and simplifies simultaneously triggered ETSI 300 328 MIMO power tests when used in conjunction with the new sensor.
