January 27, 2008 - GAO Tek Inc. is pleased to announce its new CATV instrument, GAO1191 QAM Analyzer for DVB signal analysis. This instrument features compact size and high performance. It can be used for both analog and digital TV signal analysis. In the level of frequency mode, the peak holding function can detect occasional interference. What is more exciting about this product is that it is designed and built in such a way as to make the measurements of QAM digital channels, analogue channels, and FM channels easier than ever; the built-in COM port makes data communication and saving simple. Also the software can be updated conveniently.
