All Events - Controls whether the analyzer shows all events in the window, or only data bytes.
Events include control signal changes and framing information.
Timestamping Options – Brings up the timestamping options window which has options for
customizing the display and capture of timestamps.
4.5.3 Opening Multiple Event Display Windows
Click the Duplicate View icon from the Event Display toolbar to open a second Event Display window.
You can open as many Event Display windows as you like. Each Event Display is independent of the others
and can show different data, use a different radix or character set, or be frozen or live.
The Event Display windows are numbered in the title bar. If you have multiple Event Displays open, click on
the Event Display icon on the Control window toolbar to show a list of all the Event Displays currently
open. Select a window from the list to bring it to the front.
4.5.4 Calculating CRCs or FCSs
The cyclic redundancy check (CRC) is a function on the Event Display window used to produce a checksum. The
frame check sequence (FCS) are the extra checksum characters added to a frame to detect errors.
1.
Open the Event Display window.
2. Click and drag to select the data for which you want to generate a CRC.
3.
Click on the CRC icon .
4. In the CRC dialog box, click on the down arrow to show the list
of choices for CRC algorithms. Choose an algorithm to use. Choose
CRC 32 (Ethernet). Choose CRC 32 (Ethernet) for Ethernet data or
the appropriate CRC type for serial data.
5. Enter a Seed value in hexadecimal if desired.
6. Click OK to generate the CRC. It appears in the byte information
lines at the bottom of the Event Display window. Whenever you
select a range of data, a CRC using the algorithm you selected is
calculated automatically.

4.5.5 Calculating Delta Times and Data Rates
1.
Click on the Event Display icon on the Control window to open the Event Display window.
2. Use the mouse to select the data you want to calculate a delta time and rate for.
3. The Event Display window displays the delta time and the data rate in the status lines at the bottom of
the window.
