| "I want to express my thanks for the great cooperation from the Sales Team at GAO Tek. I was a bit confused on some of the technical information while selecting the CCS to debug my target board. They were very patient in walking me through my problems. The XDS510 emulator is working great and I'm very satisfied with the performance." |

DS1191 QAM Analyzer
GAO Tek Inc. Announces New CATV Instrument, DS1191 QAM Analyzer
Toronto, Canada – GAO Tek Inc. is pleased to announce its new CATV instrument, DS1191 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.
