1. Introduction
RTX6001 is a PC based 24-bit 192kSPS 90kHz
high-performance audio analyzer with dual-channel balanced inputs and outputs, an isolated
USB port, extremely low distortions and noises, and
an extremely flat frequency response. It has been seamlessly integrated
with the
Multi-Instrument®
software to form a completed multi-function high-performance audio
analyzer.
2. Package Contents
1) RTX6001 audio analyzer unit
with accessories including a main power cable, a USB cable, a
certificate of conformity as well as a calibration report.
2)
USB hardkey containing a
Multi-Instrument Full Package software license.
3) CD (contains the copy-protected Multi-Instrument
software and RTX6001 driver)
