IOScope's available time domain measurements include:
The measurement duration can be adjusted from 0.1 to 5 seconds. The time resolution is dependent on the sample rate (typically 48 kHz).
A data cursor may be placed within the data display with a single tap. You can move the data cursor by sliding your finger to the right or left inside the data display. When the cursor is visible, measurement information associated with the cursor is displayed in a small info view above the data display. It is possible to zoom in or out on the data 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.
A double tap inside the vertical axis label area toggles auto vertical scaling on and off (independently for each measurement type).
Depending on the current auto-scaling selection, the vertical scale of the data 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).
When the device is in a portrait orientation, measurement selection controls appear near the bottom of the screen. The measurement selection cannot be changed while the app is in landscape orientation.
