Handheld Spectrum Analyzer HSA-Q1 13 GHz

The Handheld Spectrum Analyzer HSA-Q1 is designed specifically for professional countermeasures use. With a frequency range of 0 to 13.4 GHz and sweep time of just half a second, the HSA-Q1 spectrum analyzer offers unprecedented performance in a truly handheld package. The unit detects all types of RF signals within range, especially modern pulsed burst signals that can be missed by slower sweeping units.

This Handheld RF Spectrum Analyzer 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’. Yet, despite its technical capability the HSA-Q1 is easy to operate and features an intuitive, user friendly interface. Ideal for professional TSCM applications.

ComSec LLC is the North American Distributor of the HSA-Q1 Spectrum Analyzer.


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 HSA-Q1’s Waterfall (Spectrogram) function shows a real time full color graphical display of any detected signal to allow the user further analysis. This is especially useful in analyzing 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 Handheld Spectrum Analyzer 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, this Handheld RF Spectrum Analyzer 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 color will change from blue through the color 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 HSA-Q1 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.
