Precision PC Based Real Time Audio Analyzer RTA-168
 
VIRTINS TECHNOLOGY has launched a precision PC based real time audio analyzer RTA-168 (refer to www.virtins.com/VTRTA168.shtml for details). It consists of a measurement microphone, an XLR-to-USB converter, and virtual instrument software Multi-Instrument. An audio test CD is also included. All the components of RTA-168 can be packed into a small black soft pouch case provided and be carried together with your laptop or netbook. It is an indispensable tool for audio and acoustic measurements in both field and laboratory. Application examples are frequency response and distortion measurement of a loud speaker, room/car equalization, noise monitoring and analyzing, etc.. Combined with the computing power of a modern PC and the powerful virtual instrument software "Multi-Instrument", RTA-168 provides unbeatable performance-to-price ratio compared with any other types of RTA. Furthermore, Multi-Instrument software upgrade in the same license level is FREE for life.

The main functions of RTA-168 includes: oscilloscope, spectrum analyzer, sound level meter, signal generator, 1/1, 1/3, 1/6, 1/12, 1/24, 1/48, 1/96 octave analysis, equivalent continuous sound level (Leq) measurement, A, B, C, ITU-R 268 frequency weighting, linear and exponential time weighting, parameter measurements (THD, THD+N, SINAD, SMPTE IMD, DIN IMD, CCIF IMD), etc..

RTA-168 has two configurations:
1. RTA-168A (US$299.95, with Multi-Instrument Standard license, Free Shipping)
2. RTA-168B (US$349.95, with Multi-Instrument Standard license, Free Shipping)

RTA-168A comes with a ECM999 measurement microphone with extremely flat frequency response within 20-20kHz.

RTA-168B comes with a EMM-6 measurement microphone with extremely flat frequency response within 20-20kHz. Morever, the frequency response of the microphone is individually calibrated and thus compensated in the software.

RTA-168 Manual can be downloaded at: http://www.virtins.com/VTRTA-168Manual.pdf

Multi-Instrument Software Manual can be downloaded at: http://www.virtins.com/MultiInstrumentManual.pdf

Multi-Instrument software can be downloaded at: www.virtins.com/MIsetup.exe for 21-day fully functional free trial.
