Rohde and Schwarz is enhancing its R and S ETL TV analyser with a set of comprehensive functions developed for ATSC Mobile DTV (ATSC MDTV).

The new capabilities make the R and S ETL the first analyser that can perform all required measurements for installing, commissioning and maintaining ATSC MDTV networks using a single instrument, according to the company.

Broadcast drive tests are now possible.

The TV analyser is suitable for optimising ATSC MDTV single-frequency networks (SFNs).

Users will profit from its patented time-saving measurement method.

The ATSC MDTV extension to the standard allows digital television to be received on smartphones and other handhelds.

Suitable networks are currently being set up and TV transmitter manufacturers, network operators and regulatory authorities need T and M instruments such as the R and S ETL to test them, the company claims.

Using the R and S ETL-K320 software option, the TV analyser determines whether transmitters function in conformance with the ATSC MDTV specifications and whether network coverage is complete.

For coverage measurements in the field, Rohde and Schwarz also offers the R and S BCDRIVE software.

Data measured at a number of stations can be analysed in detail and displayed in a straightforward fashion using the software.

ATSC MDTV networks can also be set up as single-frequency networks.

SFNs provide more stable broadcasting reception, since all transmitters in a network broadcast signals on only one frequency.

Coverage of the broadcast area is achieved with multiple powerful transmitters, each operating on a different frequency.

To optimise SFNs, Rohde and Schwarz has developed and patented a measurement method.

The R and S ETL equipped with the R and S ETL-K321 software option allows users to precisely determine the frequency offsets of all transmitters in a network with a single measurement.

First, the R and S ETL defines a reference transmitter.

At a central point in the SFN, it then measures the frequency offset between the other transmitters and the reference.

Users immediately get all the information they need to align the transmitters.
