Transient Capture with the Vision and Revolution
Capture high-speed, high-voltage transients with the Revolution and Vision, using the optional transient capture system. Transient capture uses 1 MHz sampling for voltage, giving a 1 microsecond sample window, and…
Waveshape Triggering for Waveform Capture
A new method of triggering waveform capture in the Revolution and Vision is introduced, designed for capturing changes in power line waveform shape.
