Essentially D to A converters with built-in waveform generation memory.

内置数字到模拟转换器

2.Waveform Digitizers and Samplers(采样器)
Capture analog signals.

扑捉模拟信号

Essentially A to D converters with built-in capture memory.

内置模拟到数字转换器

3.Time Interval Analyzers(时间间隔分析器)
Measures frequencies, delays and jitter.
