The HSA-Q1 is a fully integrated portable RF Spectrum Analyser designed specifically for professional countermeasures use (TSCM). It has been designed with the highest possible technical specification to ensure maximum detection capability and has a range of invaluable features to aid countermeasures RF detection or ‘Sweeps’. Despite its technical capability the HSA-Q1 remains easy to operate with an intuitive user friendly interface.
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.
Frequency spans can be set anywhere from the whole 13.44 GHz range down to just 25 Mhz when detailed signal analysis is required. Simply move the cursor onto any detected signal and press the ‘Zoom’ button to view the signal in more detail.
The Waterfall (Spectrogram) function shows a real time full colour graphical display of any detected signal to allow the user further analysis. This is especially useful in analysing modern pulsed digital signals (or frequency hopping signals) such as those from Cellular, Wifi, Burst and GPS based devices.

RF Sensitivity can be adjusted over 5 levels: Maximum (-80 dBm), for example, to detect all signals including those in other adjacent rooms or even outside the building, down to Minimum for when location of a specific nearby signal source is required.
The HSA-Q1 features a Tune-Listen function where at the press of a button the user can direct tune into any signal detected, view the signal pattern and see the signal strength live (down to -100dBm). If required the user can also select Wide FM, Narrow FM or AM demodulation and listen to the detected signal through the built in loudspeaker or earphones. This can be especially useful in identifying conventional bugs with microphones or eliminating other innocent detected signals such as broadcast radio.
If required the HSA-Q1 can perform a ‘Background’ scan where it will learn and store the current RF environment. This can be stored and recalled at any time in the future for comparison to see if any new suspect signals have appeared in the RF environment since last checked. New signals will be highlighted on the display for closer inspection.
Persistence mode offers further analysis of any detected signal. The more ‘persistent’ the signal is (the longer it remains detected) its colour will change from blue through the colour spectrum to red for the longest present signals. This can be used to identity persistent signals that might otherwise be hidden in a noisy RF environment.
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.
For maximum flexibility the HSA-Q1 is supplied with two antennae: a Multi-Element Antenna for general use and a telescopic whip antenna for low frequency use.
The HSA-Q1 is genuinely portable for handheld use and is also fitted with a retractable stand for desktop use. The unit weighs just 1.3 Kg and is encased in a machined aluminium enclosure for ultimate durability. The internal Lithium Polymer battery pack gives 4 hours of use from one charge. The unit can also be operated continuously with the supplied charger connected. The whole package is supplied in a compact military standard carry case for ultimate protection and portability.


The HSA-Q1 is designed, manufactured and tested to highest technical standards.
