Edge/Pattern
combinations :
|
Edge
:
Rising edge, falling edge, Change of state
Pattern:
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. The
pattern must be valid for at least 20ns before the edge and 20ns
after the edge.
Edge
THEN Pattern
/
Pattern THEN Edge:
The first condition is required before the second condition.
At least 30ns is required from detection of the first
condition to the second.

Continuous:
|
Unconditionally
Continuous
:
Trigger forced internally and display updated with regular
intervals.
Conditionally

Display updated when a trigger condition
is detected. Any of

Multitasking
environment
|
|
|
Windows:
|
Windows
98,ME,2000,XP or later compatible versions.
The
power of the Windows multitasking environment is utilised to run
the 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.
|
|

Indicates trigger position.
P-trigger
line :
Indicates trigger condition-1 position in case of condition-1 THEN

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.

|
Cursors
(X, Y & Z) snap to signal edges for accurate time

useful when the display is zoomed out such that one screen pixel
represents more than one data sample).
The

intended to power the unit when front-end modules are attached,
which may require extra power. E.g.. ADC, DAC or multiplexer
modules.
