Manufactured by SAF Tehnika (Riga, Latvia), the Spectrum Compact instrument is primarily aimed at field engineers dealing with commercial mobile-phone infrastructure, satellite communications links or military communications systems.
It is suitable for the planning, installation, maintenance and troubleshooting of microwave networks, and its receiver sensitivity of -105 dBm 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 50Ω 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 40 GHz, Spectrum Compact has overall dimensions of 130 x 81 x 28 mm and a maximum weight of only 400g. It is suitable for operation in ambient temperatures ranging from -15 to 40C.
