Z Technology announces new DTV measurement capabilities 

March 27, 2006, Beaverton, Oregon: Z Technology, Inc today introduced two important DTV measurement capabilities for its networked measurement demodulator: FCC Shoulder Measurements and Transport Stream Data Measurements.

The DM1010 Measurement Demodulator, used by transmitter and test equipment manufacturers and U.S. broadcast stations, features NIST traceable RF measurement of signal strength, spectrum display with a new direct readout of shoulder energy for compliance with the FCC mask, ATSC modulation measurements for transmitter setup, and a new transport stream viewing option for DTV data content monitoring.

James Zook, Z Technology president said, "Inclusion of these two new features is a natural progression in our development programs supporting the broadcasting industry. Our DM1010 measurement demodulator has benefited from our work with customers in both ATSC and DVB-T, and recently with DVB-H formats. Z Technology has been investing in digital television since 1998, when it introduced its reference ATSC demodulator for laboratories developing new consumer chip sets."

The DM1010 measurement receiver is a self-contained measurement instrument, with front panel readout of NIST traceable signal level, SNR, EVM, MER, and Echo Profile. The instrument ships with Z Technology WinDM-Pro application software for local or remote operation, directly connected to the user's PC or connected through the Internet. The WinDM-Pro application, in addition to full instrument control, provides display of RF Spectrum with the new FCC shoulder measurement, A true I/Q Constellation Display for transmitter performance measurement, Eye Pattern for a graphic view of data sampling, and Echo Profile for critical monitoring of transmission line and antenna match. Each of these measurements are available to the user in greater detail. For example, the demodulated I and Q signals that produce the Constellation Display are available to the user as analog signals on the DM1010 rear panel. And both the Eye Pattern and Constellation displays can isolate the field sync interval for a clear presentation of transmitter performance.

In addition to the new FCC shoulder measurement, the DM1010 is now available with option TSR, a low cost ATSC transport stream content reader. This new hardware/software option analyses the transport stream outputs available on the DM1010 rear panel, and reports a full complement of transport stream information such as PAT, PID, PMT, data rates, data errors, and stream allocation statistics. The TSR option provides video thumbnails of each video stream, and flags transport stream errors in the ATSC recommended hierarchy. The option runs on a PC co-located with the DM1010 measurement receiver and includes a hardware module to provide the transport stream to the PC on a USB cable. The local PC can simultaneously run and display the TSR option along with WinDM-Pro DTV measurements. Multiple connection options including TCP/IP for network connection, RS232 for an optional local PC, and USB for the transport stream reader eliminate cable swapping.

With these two new measurement features, the DM1010 Measurement Receiver offers RF, modulation, and data reporting capabilities previously available only in instruments priced two to three times higher.

The DM1010 DTV Measurement Receiver is now shipping and is priced with all measurement and transport stream data reporting options under $13,000.
