Data Acquisition Cards for High Accuracy Measurement with SoundCheck®
For most transducer testng applications, sound cards provide more than suffieient accuracy. However, for some applications such as audio electronics testing, the lower noise floor of a National Instruments data acquisition card may be preferred.
