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.

Selecting Your Next Oscilloscope:

If you are selecting your next oscilloscope and want more insight on how to understand ENOB values measured and published by oscilloscope manufacturers, this document is for you. The effective number of bits (ENOB) is a way of quantifying the quality of analog to digital conversion. A higher ENOB means that voltage levels recorded in analog to digital conversion are more accurate. Understanding oscilloscope vendor-supplied ENOB values can be complex. This document focuses on interpretation of measured ENOB results made on oscilloscopes rather than the math behind ENOB calculations.

This document is divided in two parts and starts with an introduction in AC-DC conversion principles in general. It will present the most common circuits used for different power levels. The switching mode power supply (SMPS) converter will be the main focus as they are used everywhere in the electronics. Especially the flyback converter design in different flavors are highlighted. Nevertheless, all measurements are also applicable for other SMPS converter designs operating at higher power levels.In the second part of this document, most relevant testing methods and procedures of an AC-DC converter are highlighted. For each testing section, a fundamental part will be upfront discussed and it is followed by a presentation of a suitable measurement method. In this second part, the device under test (DUT) is considered as black box device and thus the structure is similar. Therefore, the testing parts consists of methods related to input tests, output tests and a combination of both like efficiency. Of course, some test performed at the output of the converter are also relevant for DC-DC converter, e.g. the validation of the output ripple.
