| Trigger conditions | |
| Pattern | "1", "0" and "don?t care" ("X") conditions selectable on all channels |
| Pattern valid < duration | Glitch Capture. Pattern duration may be specified in steps of 20ns to 1ms. Duration tolerance of ±20ns |
| Pattern valid > duration | Pattern duration may be specified in steps of 20ns to 1ms. Duration tolerance of ±20ns |
| 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: Trigger forced internally and display updates at regular intervals Conditionally: Display updates on detecting a trigger condition |
| Mouse/Keyboard | A trigger may be forced |

| 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. |
