Wohler offers 3G portable signal test generator
March 24, 2008
PANORAMAdtv, the video products division of Wohler, makes the Touchstone 3G portable signal test generator for digital video and audio. The palm-sized, battery-operated device is targeting a need for flexible testing of signals including 3Gb/s serial digital signals.
Disk backup, video editing, nearline data storage, and other media-focused applications involve a greater volume of data than ever before. The Touchstone device makes it easy to test and confirm these signals.
The Touchstone 3G unit can generate 37 different 10-bit video test patterns with embedded audio signals that provide programmed tones for up to eight stereo pairs. Video test patterns include motion zone plates and a pathological signal for 4:2:2 digital signals including 1080-50/60P at 3Gb/s.
Touchstone 3G can be powered by rechargeable or single-use batteries, in addition to an included universal AC supply. Touchstone 3G is extremely portable and may be carried as easily as a mobile phone. An optional carry case with integrated belt clip allows for convenient, hands-free transport.
