Trigger conditions
Pattern	"1", "0" and "don’t care" conditions selectable on all channels
Edge	On any one or combination of channels. Rising edge, falling edge, or change-of-state
Edge/Pattern combinations	Edge and pattern triggering may be combined for single captures or for conditionally continuous capture: Pattern Rising Edge Falling Edge Change of State Pattern OR/AND/THEN rising/falling edge/Change of state Rising edge/falling edge/Change of state OR/AND/THEN pattern Pattern < duration (glitch capture)
Continuous	Unconditionally: Screen updates at regular intervals Conditionally: Display updates on detecting a trigger condition
Mouse/Keyboard	A trigger may be forced

Software
Display
No. of channels	Any number of channels may be displayed.
Channel/group names	User specified signal/group names Grouped channel values may be displayed in Hex, decimal or binary
Display order / Colors	User specified
Zooming	Zoom in/out/previous/all/between cursors
Single capture	Captures a single set of data
Continuous capture display	Unconditionally: Continuously captures and displays data at a fixed update period Conditionally: Updates the display each time a specified edge or pattern trigger condition is met
Cursors	Various for time measurements, indicating the trigger point, etc.
Time measurements	The time differences between any two cursor lines or trigger line may be displayed. Take measurement easily by clicking mouse on first edge and on second edge to get the time difference. The time difference may also be indicated as a frequency.
Edge snapping	Cursors (X, Y & Z) snap to signal edges for accurate time measurements
Pattern search	Any channel. Conditions may be specified for 1, 0 and don't care conditions. Search from start/cursors repeated search
Saving to disk	Binary Data, Hex, Spreadsheet (CSV), configuration
Printed output	The timing diagrams, bitmaps, binary and hex data, may be printed. Landscape and portrait.
