MUMBAI: Prasar Bharati is vigorously pursuing its mission of making the transition from analogue to digital. Tektronix which claims to be the market leader in video test, measurement and monitoring has announced that Prasar Bharati has purchased Tektronix' innovative handheld waveform monitors for studio and field use during the digital transition.

Prasar Bharati will use Tektronix WFM91D Handheld Waveform Monitors in a mixed analogue and digital environment for studio maintenance and field production work. Because the WFM91D is a dual standard monitor, it eliminates the need for the broadcaster to purchase separate analogue and digital monitoring instruments. As part of the WFM91D's flexibility, the instrument will auto detect whether the incoming signal is composite analog video or standard definition digital video and configure itself accordingly.

As Prasar Bharati moves Doordarshan from analogue to digital it is looking to keep maintenance issues as simple as possible. The flexibility of the Tektronix WFM91D in its portability and its ability to move seamlessly between analog and digital sources allows Prasar Bharati to cost-effectively serve over 362 million viewers with the highest quality signals.

The Tektronix WFM91D Handheld Waveform Monitor is a handheld, multifunction monitor ideally suited to the monitoring needs of field production, equipment installation or any situation where portability and battery operation is required for analysis of analogue composite video and standard definition digital systems. The high-resolution, 4 in./102 mm color LCD display provides a clear picture of the incoming video signal.

Alternately, the waveform, vector or audio displays may be shown full-screen or overlaid in monochrome on top of the color picture display. In addition to the integrated LCD display, a composite video output enables routing to an external display.
