GRAS Sound & Vibration has announced two new microphones with SysCheck2 functionality, allowing remote-controlled checking of an entire measurement chain.
SysCheck2 is a proprietary technology for verifying measurement chain integrity. It allows remote, rapid health check on microphones, channel gain and cable integrity, which enables users to quickly validate calibration with a single click and no physical interaction. SysCheck2 is easy to set up with standard cables making it adaptable for any test set-up.
The verifications are made on each SysCheck2-enabled microphone connected to a CCP power module with transducer electronic data sheet (TEDS) support and measurement software with a single click. It also provides on-demand environmental data: Temperature, barometric pressure and humidity.
Released alongside SysCheck2, the GRAS 246AE microphone is intended for general use and 246AO for audiology. Both are 0.5-inch CCP microphone sets, and are improved versions of the GRAS 46AE and GRAS 46AO with added SysCheck2 functionality. Both can be accessed with many data acquisition systems and offer plug-and-play operation with Audio Precision’s APx data acquisition and Siemens Simcenter Testlab software.
The GRAS 246AE with SysCheck2 is a 0.5-inch free-field microphone set optimised for all acoustic applications where the location of the main sound source is known, and the microphone can be pointed directly at it ensuring 0° incidence. It is ideal for general acoustic testing and conforms to IEC 61094 WS2F and IEC 61672 Class 1.
GRAS 246AO with SysCheck2 is a 0.5-inch high-precision pressure microphone suitable for laboratory work and ideal for production line testing in coupler setups for test of hearing aids, earphones, headphones and headsets. It conforms to IEC 63181.
Users of Audio Precision APx analysers who want an integrated solution that is easy to set up and provides end-to-end self-verification will benefit from SysCheck2 integration to Audio Precision’s analysers. In the first collaborative effort by the GRAS and Audio Precision engineering teams, full SysCheck2 functionality is ready for use out of the box when connected to APx500 release v7.0 Measurement
Software with GRAS 12BA, 12BB or 12BE (coming soon) power modules and an Audio Precision APx series analyzer, or with an Audio Precision APx series analyzer with CCP and TEDS read/write capability.
Siemens Simcenter Testlab Signature Acquisition has integrated SysCheck2 for use with the 246AE microphone and developed a dedicated remote-check procedure, allowing it to smoothly check the validity of a calibration previously performed in the field.
GRAS also offers full functionality by way of providing a software development kit (SDK). This makes all features easily accessible with a suitable CCP-based power module, analyzer and data acquisition system, depending on the software platform.
‘By releasing this first intelligent acoustic sensor system, we are demonstrating our commitment,’ says Director of Product Management, Rémi Guastavino. ‘When combining our SysCheck2-enabled microphone systems with Audio Precision and Siemens platforms, we are effectively removing obstacles for customers who need easy, fast and accurate tests.’
