ETH4 / ETH14

DESCRIPTION

The R&S®ETH handheld TV analyzer was specially developed for coverage measurements as well as for service and maintenance work on DVB-T, DVB-H and ISDB-T gap-filler and low-power transmitters. The universal capabilities of the R&S®ETH also make it useful in the repair and development of TV components.

KEY FACTS

• TV, spectrum and network analyzer in a single box
• Frequency range up to 3.6 GHz
• High-precision demodulator (MER typ. 45 dB)
• Wide input level range (-76 dBm to +10 dBm) for quasi-error-free transport stream decoding
• Compact, lightweight, portable instrument that runs max. 4.5 hours on battery

FEATURES

• Measurement of all DVB-T, DVB-H and ISDB-T signal parameters
• Display of constellation diagram, channel impulse response, OFDM spectrum with shoulder distance and MER(k)
• Wide input level range due to integrated preselection and preamplifier
• Full-featured spectrum analyzer
• Network analysis and distance-to-fault measurement by means of integrated tracking generator (option)
• Frequency locked to external reference
• High-precision power measurement with external Rohde & Schwarz power sensors
• Field-strength measurement using isotropic antenna
• Fast and precise measurement due to realtime demodulation
• BER measurement and ASI transport stream output
• Optimized for field use: compact, lightweight instrument with rugged housing
• Easy-to-replace lithium-ion battery for long battery operating time
• Rrequnecy correction and positioning via GPS
• Reproducible measurements using user-specific measurement profile,transducers and cable models
• Convenient data exchange with PC: R&S®ETHView PC software for configuring channel tables, limit tables and measurement profiles and transferring measured data to PC via LAN or USB interface
