Hi,

Is it possible to use several IWR1642 at the same time, or is going to lead to some issues of measurements?
How to deal with the use of several IWR1642 ?

Thanks,

Alex

    Hello,
    IWR1642 is not sharing the Transmit Reference signal so that the IWR1642 is coherent as a reference. This is called Cascade mode, which is only supported by AWR1243 device.

    If you mean how do multiple IWR1642 take synchronous measurements, the Sync Input can be used with a time reference, to
    synchronize or to space-out-in-time IWR1642 sensor measurements. The CLI parameters are reconfigured for Hardware Sync input rather than
    software control. If you are trying to align 2 sensors in time, the Sync Out from the master device, can be sent to the Sync In.
