Credence Introduces Industry's First Dedicated High-Level Audio Test Solution.SAN FRANCISCO--(BUSINESS WIRE)--July 16, 1996--Credence Systems Corporation (Nasdaq:CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. ), a leading manufacturer of automatic test equipment (ATE) for the semiconductor industry, today announced the release of two new low-frequency instruments (LFIs) to meet the testing requirements of 3-D audio and other advanced digital audio devices. Field upgradable to Credence's Duo series and VistaVISION, the LF-ACP and the LF-AWG will be available for Beta sites An organization or group that is beta testing hardware and/or software. See beta test. by September 1996. Credence will demonstrate its new high-level audio test solution during SEMICON/West 96 (Booth No. 5401, Hall 4). The LF-AWG is an arbitrary waveform generator An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). that creates precision audio signals with microhertz resolution. Audio signals produced by a device under test are captured by the LF-ACP. After digitizing "Digitizer" redirects here. For the computer device, see Digitizing tablet. For the digitizer in Tablet PC's, see Tablet PC. Digitizing or digitization the waveforms, the LF-ACP couples them to the DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive processor-per-instrument architecture of the Duo. This technique provides maximum accuracy for evaluating the audio signal and eliminates the need to move large amounts of data for analysis, thereby decreasing the test time. The low noise environment of the Duo, along with the up to 20-bit accuracy of the new instruments provides the ability to verify the very high SINAD SINAD Signal, Noise and Distortion (audio measurement) (signal to noise and distortion) specification that is key to the performance of today's advanced digital audio devices. "As we strive to continually stay ahead of the pack," said James T. Healy, President of Credence, "Credence now brings key audio test technology to the market before the competition. The migration of audio devices from 'add on boards' to the PC motherboard  This article or section may be confusing or unclear for some readers.Please [improve the article] or discuss this issue on the talk page. means that our customers face higher levels of integration along with increasing price pressure. The Duo series is a solution for testing these digital mixed-signal devices, and with our new instruments, Credence again sets the value standard in digital audio test." Industry's First Complete Audio Test Solution Digital audio devices targeted to multimedia applications often specify a SINAD of 88dB or better for emerging 18-bit devices. The 120dB SINAD specification of both low frequency instruments ensures the ability to test these devices, as well as today's 16-bit devices, over their entire total dynamic range. All analog signal An analog or analogue signal is any time continuous signal where some time varying feature of the signal is a representation of some other time varying quantity. It differs from a digital signal in that small fluctuations in the signal are meaningful. conditioning is done at the test head eliminating microphonic interactions due to excessive cabling of analog signals. This also results in the lowest possible noise and best repeatability. Each instrument also features dual 16-bit voltage references that simplify fixturing and reduce time to production in this fast moving market. Reduced Test and Test Development Time The fully integrated, non Sigma-Delta architecture delivers a phase coherent clocking and triggering subsystem, reducing test times through less capture and processing time. Programming of the instruments is considerably easier than other systems due to the elimination of software interactions between the digital subsystem and the low frequency instruments. Credence's new LFIs are also field upgradable to the Company's VistaVISION. The VistaVISION is a CMOS-based test product designed to test digital mixed system devices including video DACs, video processors, and mixed signal ASICs. High-performance analog test is made possible by an electrically shielded and electromagnetically shielded environment.
