Number of Analyzer Counters and Timers
The Analyzer includes one event counter and one time counter (timer). If you try to assign
more, you get a warning.
Packets
You must assign a packet, event, or logical expression to a counter and/or timer.
Using a Counter
To use a counter:
1. Click an event to display an arrow.
2. Click a counter. This causes the counter to attach itself to the bottom of the event.
An arrow automatically connects the counter to the Trigger button.
Note: For Timers, do NOT use a timer as the first event in a sequence, since this first “event” will be the
start of recording, and this is not a precise or predictable point in time from which to start
timing. Use timers only AFTER the first event.
Setting a Counter
To set a counter:
1. Open the Recording Rules page, select an event, and drag it to the Global State or
Sequence cell.
2. Counts can only be set on a per channel basis, so press the Up or Down channel
buttons to select the channel on which the count is performed.
3. Right‐click the selected event and select Add Counter from the menu to open the
Properties dialog.
4. In the text box to the right of the label Count, enter a value. Make sure the checkbox
to the left of the word Count is checked.
5. Click the X in the top right corner of the dialog box to close the dialog. A counter
button should appear just below your selected event.
Changing a Counter Value
To change the counter value:
1. Click the small blue dot in the upper‐left corner of the counter button to display a
menu.
2. Select Change Counter Value.
3. Enter a new value in the pop‐up dialog box. The new value appears in the counter
button.
