Advanced Bit Error Rate Tester — Built around the same BERT core used in the Quasonix Receiver Analyzer, QBERT is capable of obtaining pattern sync at extremely high bit error rates, up to 3.8e-1. More importantly, it can maintain pattern sync at equal or higher levels, exceeding 4.9e-1 with PN31 patterns.

Internal Pattern Generator — Includes all standard pseudonoise (PN) patterns and user patterns up to 32 bits. For test purposes, it can insert errors manually or at a user-programmed error rate.

Simple User Interface — QBERT provides an intuitive touchscreen interface that places all functionality on-screen for simple one-touch operation.

Versatile Deployment — The QBERT chassis is sized to fit standard 19-inch rack-mounting (using provided adapter brackets). An optional portable case can be used to mount and transport the QBERT. 

Surprising Sensitivity — QPatch accommodates reception from targets up to 50 miles away within line of sight (dependent on transmit power, mode, bit rate, and forward error correction). Gain on beam is +8 dBi.

Wide-Angle Coverage — QPatch offers extraordinary wide-beamwidth performance, covering 53 degrees at -3 dB and a full 180 degrees at -20 dB.

Rugged — Built for durability and to withstand the elements, such as marine environments. Includes grade 316 stainless steel components and internal RF lightning surge protection.

Easy Set-Up — With just two coaxial cables, QPatch can be controlled remotely from a receiver over 400 feet away. RF outputs are powered through the coaxial connection, eliminating extra power cabling and connectors. 

Flexible Testing — The Quasonix BSSA has 12 independent data generators capable of emulating a multitude of best source selection challenges such as channel delay, Doppler effects, variable bit error probability, receiver sync loss, and more. Twelve PCM I/O and twelve TMoIP I/O are independently configurable as input or output, with the ability to monitor and report results for up to four simultaneous channel groups.

Rigorous, Repeatable Evaluation — Tests are precisely repeatable, so it’s easy to make valid comparisons of any equipment across a wide variety of scenarios. By including DQE framing with the exact DQM based on dynamic error probability, it’s possible to know with certainty how your BSS is performing — in the absolute and relative to theory.

System Optimization — The BSSA can help you to test and optimize your own specific BSS parameters, such as those you may be using for receiver data correlation and realignment. Refine and improve your system with no actual data lost.

Cost Savings — Whether you already own Best Source Selectors or are preparing to purchase new gear, you can use the BSSA’s results to select the best equipment for your particular needs, ensuring efficient deployment of existing hardware and cost-effective procurement of new.
