Overview

A new derivative of the 802 video signal generator (known as a signal analyzer) is now available with two digital connectors. In addition to the transmitter connector, which emulates various hosts,

a receiver connector has been added that allows a high quality display to be emulated as well. Now, inbound video (from either the generator itself or an external source) can be analyzed for data

errors and timing anomalies. Results can be displayed on the front panel or sent to an external computer via serial or GPIB for logging purposes.

Video card and set-top-box manufacturers will find this instrument invaluable for verifying signal quality, timing, and color encoding. A host's digital video interface can now be rigorously tested without

meticulous inspection of a monitor screen. A pseudo-random noise (PN) rendering application program or data file (provided) can be used to fill the video card's frame buffer with a sequence of highly

dynamic pixel values. With the resultant video signal connected to the input of the analyzer, signal quality can be measured blindly and test results delivered in simple numeric terms. In cases where the

video source cannot support the rendering of pseudo-random noise data, a "delta error" measurement technique can be alternately used, which counts flickering pixels in still-frame test images. Timing

can measured without regard to video content.

The instrument is also excellent for finding problems with cables, cable extenders, and distribution systems. Everything needed to test transmission systems from end-to-end (using pseudo-random

noise) is now available in a single instrument.
