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!

JJN Digital HSA-Q1 Main Features:

HSA-Q1 Handheld RF Spectrum Analyser 1 Mhz to 13.44 Ghz FAQsCan 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.
