Abstract :
The author reviews the historical development of digital VLF/LF modem testing. He discusses the introduction of test equipment in the following four major functional areas: (a) transmit simulation, (b) channel simulation, (c) noise and interference generation, and (d) reception characterization. He demonstrates two major trends: (1) the use of general-purpose hardware and off-line software replacing special-purpose hardware; (2) Gaussian noise, atmospheric laboratory test environments being replaced by tailored simulated electromagnetic interference and atmospheric noise
