Accuracy of the UHF electronics packages testing

Ensuring accurate testing of a UHF electronic package is the main requirement for a testing system. There are two problems: metrological certification as generator devices generating test pulses of desired amplitude and at a desired moment of time and the problem of measuring amplitude and time parameters of signals at the outputs of an electronic package. This paper observes the methods of measurement and establishes the accuracy of results, which allows metrological certification of testing systems channels in UHF band. This paper gives methods of analysis of metrological reliability of testing devices. Mathematical expressions and numerical evaluations are acquired, showing ambiguity of amplitude and time parameters of the signals at the output of generator channels of multichannel systems. Different types of devices are suggested allowing accurate testing of electronic packages in UHF band. Accuracy was taken as a primary function during the course of research. Connection between accuracy, speed (maximum clock frequency at a given number of clock pulses in a cycle) and multichannels was convincingly proven.
