Again, the purpose of this series is to address the uses and applications of these test signals. And again, there are many variations of these test signals, I try to address the basics which apply to all variations. Multiburst Having said there are many variations, Multiburst has probably more variations than any other group of test signals. The basic versions are called low band packets, high band packets, low band sweep and high band sweep. There might or might not be markers used in these signals, and there could also be user controllable markers.
All versions have one basic thing in common.
They all include many frequencies and present multiple frequencies over time. Lets look at the most common of these signals. This test signal is used to evaluate amplitude verses frequency performance in television systems. Those specific frequencies match most standards, and are traditional values. Tests usually entail observing each multiburst packet amplitude, passing the test signal thru a device under test, and again measuring the amplitude of each packet.
