Synchronizing Transmission and Reception TX/RX with USRP B210 on LabVIEW

[elbazi05]

Hello,

I am seeking your assistance with a wireless measurement project using the USRP B210 on LabVIEW. The measurement principle involves sending a 433 MHz signal for 150 µs and then listening to the sensor's response for 10 µs. The challenge in this project is to activate the reception immediately after the 150 µs transmission.

To achieve this, I have tried two methods:

State Machine: As shown in the attached photos, this method uses one state for transmission and another for reception to ensure they do not execute simultaneously. However, I am encountering difficulties in achieving the 150 µs timing while controlling each loop.

Parallel Loops: This method involves using two parallel loops to operate asynchronously. When the transmission loop is active, the second loop waits, and vice versa. If you have any ideas on how to implement this, I would greatly appreciate your input.

Thank you in advance
