JJN Digital HSA-Q1 – Supply & Training

JJN Digital HSA-Q1 RF Spectrum Analyser

Designed specifically for Technical Surveillance Countermeasures (TSCM) use, the JJN Digital HSA-Q1 is a portable RF Spectrum Analyser in a fully integrated unit. To provide the operator with maximum detection capability, the HSA-Q1 has been designed to the highest possible technical specification and includes a range of features to aid the operator in conducting TSCM sweeps. In spite of its technical prowess, the HAS-Q1 spectrum analyser’s intuitive, user friendly GUI is easy to operate.

Modern pulsed burst signals can be missed by a slow scanning spectrum analyser, so to ensure that all types of RF signals are detected, the JJN Digital HSA-Q1 features a frequency range of 1 MHz to 13.44 GHz and is able to sweep this in 0.5 seconds. The HAS-Q1’s frequency spans can be anywhere in the entire 13.44 GHz frequency range, right down to just 25 MHz to allow for a detailed signal analysis.

The 6” built-in display on the JJN Digital HSA-Q1 can provide the operator with a full screen spectrum scan, full screen waterfall, or a split waterfall spectrum display. The HSA-Q1 can learn and store the current RF environment by carrying out a background scan. The background scan can be used at any time for a comparison to check for any new signals that may have appeared. Any new signals that do appear, are highlighted by the HSA-Q1 for further inspection.

Weighing in at just 1.3 Kg, the JJN Digital HAS-Q1 is built for portable use with its handheld form factor but is ready for desktop use with its built-in retractable stand. The HSA-Q1 can provide up to 4 hours of use with its internal Lithium Polymer battery on a single charge, as well as being able to operate continuously whilst connected to the charger. To make the HSA-Q1 as durable as possible, the unit is housed in a machined aluminium enclosure and is supplied in a military standard compact carry case.

Please Note: QCC Global Ltd only supplies accredited TSCM training services to Government, Military, Law Enforcement, CPNI & Commercial Partnership clients.
