To measure linearity, a single R&S®CLG cable load generator generates the entire full digital channel load of a cable TV network. When the R&S®CLG is used together with the R&S®ETL TV analyzer, the resulting bit error ratio (BER) or carrier-tointerference noise ratio (CINR) can be directly determined in line with IEC 60728-3-1.

All types of information transmission, including the 'one-way' transmission used in broadcasting, involve feeding a radio frequency (RF) signal to an antenna. This is the essence of the most basic type of transmitter used to emit electromagnetic waves. In the real world, however, a transmitter used for broadcast applications, for example, is much more complex in terms of its functions and design. The different transmitter components must be carefully coordinated. There are many quality parameters that are critical in ensuring that a proper output signal is delivered. Rohde & Schwarz designed the R&S® ETL TV analyzer especially for broadcasting applications. The analyzer allows the measurement of the quality parameters that are relevant in analog and digital broadcasting. This Application Note describes the typical quality measurements performed during compliance testing of TV transmitters. The approach discussed here is based on the example of Rohde & Schwarz terrestrial transmitters for analog TV and DVB-T/H.

Broadcasting transmitters are subject to particularly stringent standards with respect to broadcast signal quality, because even small faults can lead to service disruptions for many viewers. A single instrument, the R&S®ETL TV analyzer, performs all required ISDB-T transmitter measurements, from the initial acceptance testing for the transmitter, to measurements performed during commissioning and preventive maintenance.

DVB-T signal quality is determined by measuring the modulation error ratio (MER). However, a poor MER does not indicate its causes since different interference factors overlap at the transmitter when a signal is generated and transmitted. The R&S®ETL TV test receiver now has a unique new measurement capability that makes it possible to demonstrate to what extent the modulator's phase noise affects the MER.

Despite the advent of advanced digital transmission methods, analog broadcasting remains highly important. Until now, measurements on FM transmitters in connection with acceptance testing, commissioning and maintenance required using a variety of T&M instruments.The R&S ETL TV analyzer combines these instruments' capabilities in a single unit and can completely replace them. Now, for the first time, acceptance test measurements can be conducted on FM transmitters quickly and easily using just one compact test instrument. The R&S ETL provides the functionalities of a power meter, spectrum analyzer, audio generator, FM measurement demodulator, stereo decoder, audio analyzer and more in just one box.

Keeping an ATSC (or ATSC Mobile DTV) single-frequency network (SFN) running smoothly not only requires that every single TV transmitter functions properly – the RF performance criteria echo pattern and frequency deviation also have to be strictly complied with. The R&S®ETL TV analyzer enables operators to check these crucial RF parameters at a glance with unmatched precision. The patented implementation achieves an echo delay resolution of one nanosecond, which is nearly a hundred times higher than in conventional approaches. This allows more precise control and adjustments of the several transmitters within the ATSC (or ATSC Mobile DTV) SFN and thus helps to ensure excellent coverage for the receivers.

The terrestrial television standard DVB T2 is gaining in significance as a result of the growing scarcity of available frequencies. New systems are being tested in many countries around the world. Other countries have already completed the introductory phase for DVB T2. Broadcasting transmitters are subject to particularly stringent standards with respect to broadcast signal quality, because even small faults can lead to service disruptions for many viewers or even disrupt adjacent channels.A single instrument, the R&S®ETL TV analyzer, performs all required DVB-T2 transmitter measurements, from the initial acceptance testing for the transmitter, to measurements performed during commissioning and preventive maintenance.The measurements described here satisfy many country-specific and customer-specific test specifications. Users need only set the limit values accordingly.
