5 Press the Mode softkey to select one of these operating modes:
• PC — PC controls the VPT1000.
• Asynchronous — oscilloscope controls the VPT1000 for frame decode information
only.
• Synchronous — oscilloscope controls the VPT1000 for frame decode along with
synchronous slot/segment timing boundaries.
In PC Mode The VPT1000 must be connected to the PC via LAN. The PC must have the
appropriate FlexRay protocol analysis software.
In Asynchronous Mode
This presumes you have established LAN communication as described in “Setting Up
VPT1000/Oscilloscope LAN Communication” on page 108.
1 Press the Baud softkey to select a baud rate of 2.5 Mb/s, 5Mb/s, or 10 Mb/s to
match your device under test.
2 Press the Channel softkey to select channel A or B.
In Synchronous Mode
This presumes you have established LAN communication as described in “Setting Up
VPT1000/Oscilloscope LAN Communication” on page 108.
To use synchronous mode, you must load a FIBEX file (.xml) which defines the global
scheduling parameters of your device Under test.
1 Ensure the synchronous mode of operation is selected.
2 Copy the FIBEX file to a USB storage device.
3 Connect the USB storage device to the oscilloscope.
4 Press the FIBEX File softkey. Navigate to the FIBEX file and load it.
The oscilloscope stores the pertinent synchronous timing parameters in non-volatile
memory. If your schedule changes you will need to re-load the new FIBEX file.
5 Press the Channel softkey to select channel A or B.
NOTE
If the VPT1000 loses synchronization, then press the Mode softkey (in the VPT1000
Menu) on the oscilloscope to cycle through the modes and restore synchronization.
