Comprehensive Simulation of Master, Slave and End Nodes in A 2 B ® Networks
Infotainment Test Device ITD 1024
The complexity, cost and weight of audio systems are significantly reduced with the Automotive Audio Bus (A 2 B ® ) from Analog Devices Inc. Regardless of their hierarchical structure or use as master or slave, all A 2 B ® products must be adequately tested before use. This applies, for example, to HiFi amplifiers/loudspeakers, head units, eCall systems, microphones, vibration/noise suppression units, actuators or sensors.Our small and very compact infotainment test system ITD 1024 takes on this task for you: It comprehensively and extremely reliably tests all A 2 B ® signals and communication in all phases of the product development process - during development, for validation and in production.

Sound Level Indicators
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.An important attribute to consider when searching for a suitable sound level meter is its type or class. The type or class of a sound level meter defines the device's accuracy as per American National Standards Institute (ANSI) or International Electrotechnical Commission (IEC) guidelines. Typically, "type" is the grade according to the ANSI S1.4 standard, whereas "class" is the grade according to the IEC 61672 standard. There are two types or classes assigned to sound level meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 sound level meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used. PCE sound level meter products are lightweight, easy-to-use and manufactured in accordance with the highest industrial standards.
