FlexRay and PicoScope 5444B

Postby PhreakShow » Tue Apr 12, 2016 11:28 am

Hi everyone.

I am trying to read a 10MBit/s Flexray with my new 5444B. I attached two probes to the bus lines, and ground.
The sample rate is set to 500MS/s and 8 bit hardware resolution.

I can see the frames, there's a bit of noise but the signal is clearly distinguishable. Serial decoding is set to the correct channel, with a threshold of 2V and a 600mV hysteresis.

I attached a screenshot of my setup. it seems that the decoder is sampling, while the bus is idle, and stops after it starts transmitting. Is this just a setup issue?

Hi,

Could you post a psdata file of the issue, here :D We can have a look once we have the file.

File menu -> save -> enter file name (file type should be set on psdata)
