Tektronix Enhances Digital Video Test Generators

4/8/2003 - Tektronix, Inc. (NYSE: TEK), the market leader in video test, measurement, and monitoring, announced three important enhancements to its current digital video test instruments for digital equipment manufacturers, systems integrators, and broadcasters.

One of the side effects of the digital transition is the increasing number of formats, standards and interfaces - all intended to better leverage digital technology. With many of the new interfaces becoming commonplace or standard on both professional and consumer digital video equipment, Tektronix is responding to its customers test needs by introducing two new interfaces for its MTX100 MPEG Recorder and Player - a SMPTE 310M interface and an IEEE1394 (Firewire) interface. In response to the variety of digital technologies being employed, digital video engineers are testing their digital equipment and systems in more demanding ways than ever before to ensure the highest level of quality and interoperability. To help meet this increasing need for digital test an HD-SDI Stress Test module is being introduced for the Tektronix TG2000 Multi-format Video Signal Generator Platform.

"Our customers involved in the manufacturing, installation, or day-to-day operations of digital video equipment asked for more capabilities to meet the growing number of standards on the interface and testing front, and we've listened," said Todd Biddle, General Manager, Video Business, Tektronix. "These new options for the MTX100 and the TG2000 increase flexibility of the instruments and provide the user with the variety of interfaces and capabilities that they've come to expect from Tektronix."

New Interface Support
Widely accepted as a standard transport stream interface in low-noise environments, the SMPTE310M interface provides direct point-to-point connection between DTV devices for transmission of MPEG-2 transport streams. The MTX100, with the SMPTE 310M synchronous serial interface, now supports 19.39 Mbps for 8-VSB terrestrial broadcasting. The same option also provides additional flexibility by including an ASI interface, allowing for the acquisition or play out of transport stream data in ASI format. The MTX100 SMPTE 310M interface provides for the stimulus of DTV devices under ATSC standards, as well as the record and play out of ATSC transport streams. Streams captured in this manner can then be subjected to off-line analysis and verification of ATSC compliance via a stand-alone ATSC transport stream analyzer, such as the Tektronix AD953-II MPEG Test System.

With the IEEE1394 Firewire interface, the MTX100 can be used for design verification and manufacturing test of digital consumer and professional products. The MTX100 IEEE1394 Interface provides two 4-pin Firewire connectors and one ASI input/output. Complying with the S-400 IEEE1394 standard, the interface provides for point-to-point connection to target Firewire devices, a target selection function (becomes active when multiple devices are connected), STB and D-VHS deck emulation, support for partial transport streams, and ASI/IEEE1394 bi-directional conversion. The ASI interface supports packet/burst output mode in the output and a maximum transport stream data rate of 200 Mbps.

Both the SMPTE310M Interface and the IEEE1394 interface can be ordered as a factory installed option in the MTX100 MPEG Recorder and Player. Those users wishing to upgrade their MTX100 with either interface should contact Tektronix customer service to arrange for on-site or send-in service.

Stress Testing High Definition Digital Equipment
The HDST1 Module for the TG2000 Multi-format Video Signal Generator Platform adds stress test capability for SMPTE 292M HD-SDI signals to the current TG2000 module portfolio. The HDST1 is an independent module of the TG2000 and incorporates one HD-SDI signal input and one HD-SDI stressed output. Any high quality HD-SDI signal, such as that from a test signal generator, camera, VTR, or production switcher, can be used as the input signal. The HDST1 is an ideal source of stressed HD-SDI video when paired with the TG2000's HDVG1 Digital HDTV Generator Module, which provides a high quality signal and clock frequency offset feature. The HDST1 Module can be ordered as a factory installed option in the TG2000 Multiformat TV Signal Generator Platform or as an in-field upgrade.
