Interference analyser

Monday, 17 August, 2009



Agilent has introduced an interference analyser option for its FieldFox RF analyser, an integrated RF handheld for wireless installation and maintenance (I&M). The company has also introduced claimed industry-first spectrum analyser features.

FieldFox’s speed, 1.5 updates per second, is said to be the world’s fastest in the commonly used 20 MHz span and the 3 kHz resolution bandwidth. It offers 92 dB dynamic range and fast sweep times for interference detection with resolution bandwidths under 30 kHz.

The FieldFox analyser option includes quick, easy detection and monitoring of intermittent interference signals in the field using the spectrogram and waterfall display.

Features include what is claimed to be the world’s first RF analyser for uplink and downlink TDD signals (eg, LTE and WiMAX) and TD-SCDMA; one-button measurements offering the first LTE suite of power measurements, including channel power, ACPR and OBW; and the ability to play AM/FM audio via speaker or headset, which is especially useful in identifying demodulating modulated signals.

It integrates six key I&M measurements into one unit with test times that are more than 50% faster than other testers. Key measurements include: cable and antenna test; spectrum, interference and vector network analysis; true average power measurements; and a vector voltmeter.

QuickCal is integrated and used to calibrate the instrument without a calibration kit.
