The DECAQ
DECAQ systems provide appropriate architecture to address both standard and complex multi-channel tasks. Using the same stable modular platform for high-quality signal conditioning, the compact DECAQ can contain up to 192 channels in a single chassis.

From portable measurements to industrial-scale laboratory applications, system features such as high channel density, high dynamic range, low noise performance and distortion, accurate synchronization and integrated data capture and analysis guarantee peace of mind during product development, prototyping and troubleshooting.
Robust Design
Designed to withstand fluctuations in technology, the DECAQ’s robust design keeps it ahead of the game. Machined from aluminium, the DECAQ can withstand shock and vibration while operating in environmental temperatures from -20 °C up to
+62 °C, depending on system configuration.
Conduction Cooled
Internal conduction cooling ensures no dusty air circulates within the chassis. Some chassis may never require fan cooling while others contain fans which only need to operate under high temperatures. In all cases fans can be switched off during sensitive acoustic measurements.
Real Time Operating
Notwithstanding the system’s integrated software with playback capability, the DECAQ also makes use of a professional real time operating system, namely Windriver’s VxWorks®, on all its system Power Supply and Controller boards. This ensures fast, logical and safe decisions when operating as a standalone unit.
Rack Mounted Systems
DECAQ systems can also be housed in compact, machined aluminium RackMounts. Chassis are recessed in each RackMount to ensure all cables are contained behind the rack’s front face.
Connected and Adaptable
All QuantusSeries instruments come with embedded software for what they believe to be the essentials. Use MECALC’s RESTful interface to springboard your great software idea, as well as their embedded acquisition software to set up, calibrate, trigger, monitor and more.
Whether you choose to interface directly with our instruments or prefer a fully integrated software package, we have the versatility to complement any specific hardware-software combination.
