Introducing the world's smallest serial digital video test pattern generator, PENPAL-sdi generates 26 video test patterns and 4 stereo audio signals. Each 10 bit video test pattern is encoded according to Rec.ITU-R BT.601. and transmitted serially according to Rec.ITU-R BT.656. AES digital audio signals are embedded according to SMPTE 272.

Operating in 625 or 525 line standards, PENPAL-sdi is the perfect tool for every broadcast engineer. Powered by a 3V lithium battery, or an optional AC adapter and weighing at less than 6 ounces, you can take it anywhere, confident that you can generate serial digital test patterns & audio tones at the touch of a button whenever you want them.

This level of integration and performance has been achieved utilizing video processing and compression techniques optimized for reduced power consumption and the 10 bit all digital processing and the high stability crystal eliminates all noise and distortion.
