The JJN Digital HSA-Q1 is a handheld, fully integrated RF Spectrum Analyser featuring an ample frequency range from 1 MHz to 13.44 GHz with a sweep time of only 0.5 seconds!

The HSA-Q1 Handheld RF Spectrum Analyser is specifically designed for maximum detection capability in professional countermeasures RF detection or Sweeps. To ensure the detection of all types of RF signals, the HSA-Q1 presents with an extensive frequency range from 1 MHz to 13.44 GHz with a remarkable sweep time of just 0.5 seconds in Full Range and an even shorter 0.2 seconds sweep time in the Lower Range. With this kind of frequency span, you can detect all sorts of RF signals and in particular the modern pulsed burst signals that are often missed with slower sweeping equipment.

The RF sensitivity can be adjusted over 5 levels, ensuring detection for signals in next-door rooms or outside the building with Maximum sensitivity of -80 dBm in Sweep, as well as detection when a specific nearby signals source is needed with Minimum sensitivity of -100 dBm in Direct Tune. 

The Waterfall Spectrogram Function displays in real-time and full-color graphical display of any and all detected signals, thus allowing further analysis. This comes in handy when trying to discover modern pulsed digital signals or frequency-hopping signals from the latest technology, such as Cellular, Wi-Fi, GPS, or Burst-based devices. Also helpful is the Persistence mode which changes the color of the signal from blue to red for the longest detected signal allowing for even greater analysis and identifying continuous signals that might otherwise be hidden in a noisy RF environment.

The Tune & Listen function grants you the option where pressing a button allows you to direct tune in to any detected signal, view its pattern, and signal strength live. The Memory log of the device can be stored in the included USB stick with a time&date stamp, and if needed, featuring also is a Background scan with which you can store and recall past RF environments for additional comparison to newer RF environments in the future.

The HSA-Q1 is a portable device for handheld use however also fitted with a retractable stand should it be required for desktop use. The device provides an intuitive user-friendly interface. For maximum durability, it is protected in a machined aluminum enclosure and comes in a compact military standard carry case.

Handheld RF Spectrum Analyser 1 Mhz to 13.44 Ghz FAQs

Can the RF sensitivity of the HSA-Q1 be adjusted?
Yes, the RF sensitivity of the HSA-Q1 can be adjusted over 5 levels. This feature allows users to fine-tune the device’s sensitivity to detect signals as faint as -80 dBm in Sweep mode and -100 dBm in Direct Tune mode, making it versatile for detecting signals in various environments, whether they are from next-door rooms or outside the building.


Does the HSA-Q1 have a Tune & Listen function?
The HSA-Q1 features a Tune & Listen function that allows users to directly tune into any detected signal to view its pattern and signal strength live. This function, combined with audio demodulation options (Wide FM, Narrow FM, and AM), enables users to listen to the demodulated audio through the built-in speaker or provided earphones, offering a practical way to distinguish between different types of signals.


How does the Memory log function work on the HSA-Q1?
The Memory log function of the HSA-Q1 enables the storage of detected RF environments on the included USB stick with a time and date stamp. This allows users to store and recall past RF environments for comparison with newer scans, making it easier to identify new signals or changes in the RF landscape over time. It’s a useful feature for ongoing surveillance and signal monitoring tasks.


How fast is the sweep time of the HSA-Q1?
The HSA-Q1 boasts a sweep time of just 0.5 seconds in Full Range and an even faster 0.2 seconds in the Lower Range. This rapid sweep time enables the device to quickly scan through its entire frequency range, ensuring that even the briefest signals can be detected. The device’s speed makes it particularly effective for identifying modern pulsed burst signals that could be missed by slower equipment.


Is the HSA-Q1 portable?
The HSA-Q1 is designed for handheld use, making it highly portable, but it also comes with a retractable stand for desktop use when needed. Weighing just 1.3kg and with a battery life of up to 4 hours, it offers flexibility for on-the-go operations while still providing the option for stationary use during extended monitoring sessions.


What is the build quality of the HSA-Q1?
The HSA-Q1 is encased in a machined aluminum enclosure, ensuring maximum durability and protection. It is designed, manufactured, and fully tested in the UK, meeting high-quality standards, and comes in a compact military standard carry case for added protection and convenience during transport and sweeps.


What is the frequency range of the JJN Digital HSA-Q1?
The JJN Digital HSA-Q1 covers a frequency range from 1 MHz to 13.44 GHz. This wide range allows it to detect a broad spectrum of RF signals, making it suitable for professional countermeasures and RF detection sweeps. Its ability to cover such an extensive frequency range ensures that users can detect both low and high-frequency signals with a single device.


What is the Waterfall Spectrogram Function on the HSA-Q1?
The Waterfall Spectrogram Function on the HSA-Q1 displays detected signals in real-time on a full-color graphical display. This function is invaluable for analyzing modern pulsed digital signals or frequency-hopping signals, providing a visual representation that helps in identifying and differentiating signals in a noisy RF environment. The color-coded persistence mode further aids in signal analysis by highlighting the longest detected signals.


What type of antennas does the HSA-Q1 come with?
The HSA-Q1 is supplied with two types of antennas: a Multi-Element Antenna for general use and a Telescopic Whip Antenna for low-frequency applications. These antennas enhance the device’s versatility, allowing users to optimize signal detection across the HSA-Q1’s broad frequency range by selecting the appropriate antenna for their specific needs.
