Trigger conditions: (top)
Trigger Methods: Pattern
|
|
| (Pattern valid for any duration) | 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 1 ms. Duration tolerance of ±20ns |
| Pattern valid > Duration | Pattern duration may be specified in steps of 20ns to 1ms. Duration tolerance of ±20ns |
| Triggers On: | Rising edge, falling edge, either rising or falling edge (change of state), of any one or combination of channels |
| Mouse/Keyboard | Trigger may be forced. |
Trigger Methods: Combination Pattern/Edge
|
|
| Edge OR pattern | Edge or pattern condition that occurs first will cause a trigger. |
| Edge AND Pattern | For a trigger the edge condition must occur while the pattern condition is valid. |
| Edge THEN Pattern | The first condition is required before the second condition. At least 30ns is required from detection of the first condition to the second. |
| Application of trigger conditions | |
| Single capture | Captures a single set of data |
| Continuous capture display: | Unconditionally Continuous: Trigger is forced internally and display updated with regular intervals. Conditionally Continuous: Display is updated when a trigger condition is detected. Any of the above trigger conditions may be set as described above.The display is updated on detection of a specified trigger condition. |
Software: (top)
| Supported Operating Systems: | Microsoft Windows 98,ME,2000,XP,Vista32 or later compatible versions. |
| PC | Data capture speed is unaffected by PC- speed Ease of use: The software is very easy to use. Most functions are directly selectable by means of function buttons on the main scree |
| Multitasking environment | Run the logic analyzer software and user’s unit under test (UUT) software simultaneously (if the UUT is PC based). Hardware that interfaces with the PC may be driven from the PC while real-time measurements are performed on the hardware. (The logic analyzer and UUT software are simultaneously run on the same PC). The analyzer and the user program may be viewed simultaneously in the Windows environment. |
| Ease of use: | The software is very easy to use. Most functions are directly selectable by means of function buttons on the main screen. |
| User UUT application program launching: | The user application program may be run from the logic analyzer program menu or from Windows. |
Display
|
|
| No. of channels: | Any number of channels may be displayed. |
| Channel/Group names | User specified signal/group names |
| Display order: | Channel display order user specified |
| Display Colors | Specify colors for individual signals, background. |
| Zooming: | Data zoom: Zoom in/out/previous/all/between cursors/etc All captured data may be viewed on one screen. Zooming in to only a few samples displayed on the screen Easy data display window sizing using the mouse. |
| Single capture | Captures a single set of data |
| Continuous capture display: | Unconditionally Continuous: Trigger forced internally and display updated with regular intervals. Conditionally Continuous: Display updated when a trigger condition is detected. Any of the above trigger conditions may be set as described above. Updates the display each time a specified edge or pattern trigger condition is met |
| Cursors: | T-trigger line: Indicates trigger position. P-trigger line: Indicates trigger condition-1 position in case of condition-1 THEN condition-2 setting. S-Cursor line: Indicates data search positions. X, Y and Z-cursor: For time measurements. The values of the X and Y cursor lines, where they intersect the signal lines are shown. |
| 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. (Especially useful when the display is zoomed out so that one screen pixel represents more than one data sample). The signal edges to which the cursors lines have been snapped are indicated |
| Pattern search: | Any channel conditions may be searched for. 1, 0 and don't care conditions specified.
Also repeated search |
| Saving to disk-formats | Binary data, Hex, Spreadsheet(CSV), Configuration |
| Printed output: | The timing diagrams, bitmaps, binary and hex data, may be. Landscape and portrait. |
