Tiny new hand-held spectrum analyser can measure signals up to 40GHz

Capable of carrying out measurements on microwave signals at frequencies as high as 40GHz, a remarkable new SAF Tehnika hand-held spectrum analyser is now available from Link Microtek. The versatile Spectrum Compact instrument is primarily aimed at field engineers dealing with commercial mobile-phone infrastructure, satellite communications links or defence communications systems. It is an ideal tool for the planning, installation, maintenance and troubleshooting of microwave networks, and its exceptional receiver sensitivity of -105dBm enables even weak signals to be detected and analysed. Typical applications include antenna alignment, interference detection, cross-polarisation adjustment and measurement of antenna gain. Designed for comfortable outdoor use either at ground level or up a mast, Spectrum Compact features an intuitive, easy-to-learn GUI and a resistive LCD touchscreen that allows it to be operated with gloved hands. The instrument incorporates a 50ohm SMA input, which enables it to be connected to almost any antenna using standard waveguide flange adapters. There is also a mini USB port for recharging the polymer lithium-ion batteries and transferring saved spectrum scans to a PC for enhanced data analysis using the Spectrum Manager software supplied with the unit. Available in five different models covering frequency bands from 2 to 40GHz, Spectrum Compact has overall dimensions of just 130mm x 81mm x 28mm and a maximum weight of only 400g. It is suitable for operation in ambient temperatures ranging from -15C to 40C, says the company.
