PRBS-Sequency for correlation

Post by darianschaab »

This seems to be impossible as there is no possibility to rearm the trigger in streaming mode right?

2. Send my own PRBS-sequency and trying to synchronize the output with the streamed input data.
--> My own PRBS signal does not reach 20 kHz. It becomes blurry close to 1 kHz.
--> There is no way to start measurements and AWG synchronously.

Do you have any suggestions for me to find a way out of this, beside buying another device?

Dear Ladies and Gentleman,

I use a Picoscope 4262. I would like to send a PRBS-sequency with 20 kHz while recording the Channels A and B.

For my application I need to now the state of the PRBS-sequency so I see the following options:
1. Activate the internal AWG with a PRBS-sequency, recording the data in streaming mode while storing the triggerevents as AWG-output crosses 0 V.
--> This seems to be impossible as there is no possibility to rearm the trigger in streaming mode right?

2. Send my own PRBS-sequency and trying to synchronize the output with the streamed input data.
--> My own PRBS signal does not reach 20 kHz. It becomes blurry close to 1 kHz.
--> There is no way to start measurements and AWG synchronously.

Do you have any suggestions for me to find a way out of this, beside buying another device?
