Handheld spectrum analyser

The HSA-Q1 is a fully integrated portable RF Spectrum Analyser designed specifically for professional countermeasures use (TSCM).

13.4 Ghz bandwidth

The HSA-Q1 features a wide 1 MHz to 13.44GHz frequency range with a sweep time of just 0.5 seconds (faster in shorter spans) to ensure detection of all types of RF signals especially modern pulsed burst signals that can be missed by slower sweeping units.

Scan at 27 Ghz per second

+ Details

Frequency spans can be set anywhere from the whole 13 Ghz frequency range down to just 25 MHz when detailed signal analysis is required. 

Spectrum and waterfall display

+ Details

The display can provide full screen spectrum scan, full screen waterfall, or split waterfall spectrum display. 

Background scan

+ Details

This is a very powerful feature. The HSA Q1 can perform a background scan where it will learn and store the current RF environment. It can be recalled at any time for comparison to see if any new signals have appeared, In the RF environment since last checked. New signals will be highlighted on the display for closer inspection. 

Feature rich

Features include Persistence Mode, where by the longer a signal remains detected, it’s colour will change from blue, through the colour spectrum to red for the longest persistence signals.

The memory log function means sweep data can be stored by simply connecting a USB stick. Sweep Data will be stored in time and date format and displayed graphically to be recalled at any time for further graphical analysis.
