VT RTA-168A/B is a PC based USB Real Time Acoustic Analyzer, Sound Level Meter, Distortion Analyzer, Polarity Tester. VT RTA-168A comes with an ECM999 measurement mic. VT RTA-168B comes
with an EMM-6 measurement mic. Both microphones have an extremely flat frequency response from 20Hz to 20kHz. Each EMM-6 also comes with its very own frequency response file, which can
be used in the software to further improve the accuracy.
