overview
model td4900, an apparatus for testing merging units in laboratory or field environment. it supports various types of signal input such as traditional analog signals, analog small signals and digital signals of meeting various iec protocols.
the following tests are include: conformance test of meeting dl/t 860, accuracy test, performance test of sampled output interface, clock synchronization (error of time giving, error of time keeping and abnormal signal of time giving) and network influence test.
large lcd touch screen, more intuitive of value display and easier operation. combine with the proprietary software and computer, support semi-automatic or full-automatic test, data management and report export.
