Two new hand-held RF spectrum analysers weighing 560 grams and with a lithium-ion battery providing more than three hours of operation from each charge have been launched by Aim-TTi. Improved specifications mean models in the new series 5 are available in 3.6GHz and 6.0GHz versions and maintain a true handheld format whilst offering bench-top level features. Signal input is via an N-type connector.


The analysers incorporate a large high resolution colour TFT display with touch screen control.

The DANL noise figure is better than -160dBm/Hz and a minimum full scale reference level of -40dBm allows signals down to -120dBm to be observed. RBW and VBW are adjustable from 300Hz to 10MHz in 1:3:10 sequence.

Multiple traces can be displayed in contrasting colours, and trace modes include peak hold and multi sweep averaging. Multiple detector modes are selectable. Large internal storage is provided for traces, setups and complete screen images.

Connectivity is provided for USB Flash drives and for direct USB connection to a PC. Internal storage extends to nearly 2GB, and the internal filing system supports user specified names and time stamping from a real-time clock.

Additional features include automatic measurements of CP, ACPR and OBW, waveform demodulation, complex limit patterns with limits comparator, and triggered logging of up to 25,000 results.

The new series 5 analysers supplement the widely adopted PSA series 2 which is available in 1.3GHz and 2.7GHz versions.
