Hand-held spectrum analyser can measure signals up to 40GHz

Link Microtek has released a hand-held spectrum analyser that is not much larger than a smartphone and is claimed to be able to carry out measurements on microwave signals at frequencies as high as 40GHz.

Manufactured by SAF Tehnika, the versatile Spectrum Compact instrument is primarily aimed at field engineers dealing with commercial mobile-phone infrastructure, satellite communications links or military communications systems.

It is suited for the planning, installation, maintenance and troubleshooting of microwave networks, and its receiver sensitivity of -105dBm enables weak signals to be detected and analysed. Typical applications include antenna alignment, interference detection, cross-polarisation adjustment and measurement of antenna gain.

The instrument incorporates a 50O SMA input, which can connect it 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 130 x 81 x 28mm and a maximum weight of 400g. It is suitable for operation in ambient temperatures ranging from -15 to 40°C.
