The Signal Chart provides an overview of the standard test signals supplied with each version of the 1515, as well as their possible applications. Please contact Magni Applications Engineering if you have a requirement for a test signal not listed here: we will be happy to quote on the development of custom signals (see also "Signal Development"). -GENLOCK The 1515may be sync and burst locked (fully genlocked) to an external reference signal or operated from its own internal oscillator.
