Abstract
The development of technical parameters of the IEEE Std 1057 for digital waveform recorders in previous versions are introduced in detail, the idea of the thirteen parts characteristics of the standard involved is explored, and the six basic methods used are analyzed. At the same time, some problems in the standard are discussed, including time base errors, multi-channel synchronization, absolute delay, trigger parameters error, sinusoidal fitting convergence, and other issues. Future development of the direction about this standard is also prospected.
