      產品詳細介紹Product Introduction

      Economical TV transmitter testing

      The R&S®ETC compact TV analyzer offers a comprehensive set of measurement functions for DVB-T2, DVB-T/DVB-H and ISDB-T digital TV transmitter testing. It is also useful for service and maintenance of TV transmitters as well as for testing modulators in R&D or quality assurance environments. The design of the analyzer is ideal for coverage measurements in broadcast network planning.

      The R&S®ETC is specialized in TV analysis and also performs spectrum and scalar network analysis as well as power measurements. For tests that require higher sensitivity and selectivity, users can activate an integrated preselector followed by a preamplifier.

      The core component of the R&S®ETC is an FPGA-based realtime digital TV demodulator that optimizes realtime BER measurements and provides a demodulated MPEG-2 transport stream at the ASI output. The instrument also offers a comprehensive set of transmitter measurement functions including amplitude, phase and group delay measurements for DVB-T2, DVB-T and ISDB-T. Further advantages of the compact TV analyzer are its high measurement speed and fast booting and mode switching times, which significantly reduces the time needed for test procedures.

      To facilitate data exchange and monitoring, the R&S®ETCView Windows-based PC software, which comes with the instrument, allows users to document measurement results. The data can be transferred via a USB or LAN interface.
