SignalScope includes a multi-channel oscilloscope for viewing input signal waveforms in real time. The oscilloscope features three triggering modes, with adjustable threshold and slope parameters.
A data cursor may be placed within the oscilloscope display with a single tap. You can move the data cursor by sliding your finger to the right or left inside the oscilloscope display. When the cursor is visible, signal information associated with the cursor is displayed in a small info view above the oscilloscope display. It is possible to zoom in or out on the oscilloscope display with a two-finger pinching gesture, and to pan the display, while zoomed in, with two fingers. A double-tap resets the display zoom and a second double tap turns off the data cursor. Cursor peak tracking can be cycled between max, min, and off with a triple tap.
When the device is in a portrait orientation, auto-scaling controls appear near the bottom of the screen. Selecting Up or Down will only automatically adjust the scaling of the display when the absolute peak signal value gets larger or smaller, respectively.
Depending on the current auto-scaling selection, the vertical scale of the oscilloscope display may also be altered by a single-finger slide, or with a two-finger pinching gesture inside the vertical axis region (the region containing the vertical axis title and labels).
You can adjust the time scale of the oscilloscope with a two-finger pinching gesture inside the horizontal axis region (the region containing the horizontal axis title and labels). Sliding a single finger within this region will change the time offset of the display, which can be useful for viewing the signal's behavior before a trigger event. A double tap within this axis region will reset the time offset to 0 (the time at the left side of the display will be 0.0 s).
The oscilloscope tool supports time scales between 0.1ms and 1s/div.
