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

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 E
vent 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.
