Per-cycle "Synthesized" Waveforms and Statistics
|Waveforms||A time-correlated waveform of any per-cycle Numerics Table measurement parameter may be created and displayed anywhere on the grid. Up to 12 detailed per-cycle Waveforms may be displayed at one time, with up to 40 waveforms total (channels, memories, zooms, math, and per-cycle Waveforms) displayed at any one time.|
|Statistics||Detailed statistics on up to 12 per-cycle Numerics Table measurement parameters may be displayed at one time.|
|Operation||Press "Zoom+Gate" button to create zooms of all voltage, current and mechanical signals (analog or digital) and simultaneously gate the Numerics and Statistics tables to the zoomed area. Displayed per-cycle "synthesized" Waveforms are simultaneously time-correlated to the zoomed area. Scroll through the full acquisition using Zoom position and ratio (size) controls and view instantaneous updates of table values.|
