CC1310: Production Line radio test: need to test TX and RX, or just TX?

Part Number: CC1310


Hello,

   I'm investigating how to test the radio of a CC1310 in production. The design is based on the CC1310 Launchpad. In production do we need to test Tx and Rx, or just Tx? In other words, is there any component problem that could cause Tx to pass but Rx to fail? Time is money ($1 per minute) so the faster we can go, the lower the cost.

Thanks,

Derek

    Derek,

    I would say in order of importance.

    • TX RF output power
    • TX RF center frequency ( measured to 1PPM resolution )
    • TX active current (at max power)
    • Device sleep current
    • RX sensitivity

    The reason I but RX sensitivity at the bottom is that you usually catch the RF issues by checking the TX, however their are some corner cases that can slip thru. Its really up to each designer to decide if they want to spend the extra test time for RX sensitivity (its typically slow and error prone, you will get a some false failures)
