    CYBLE-224110 Transmit power with MTK carrier wave test mode

    jechc_4023571

      Hi,

      I'm having trouble getting the right output power with the test firmware from KBA220073 in continuous wave mode.

       

      Executing "TXP 15 0 1500" gives me pulses that I measure close enough to 0dBm.

      But with "TXC 15 0", the measured power is much lower, around -35dBm.

       

      I can vary the power from -18dBm to +3dBm, but in both cases with "TXC" the measured power is always 35dBm lower.

       

      Any ideas?  Could it have something to do with the external power amplifier control lines not being correctly toggled in the continuous carrier wave mode?

      Thanks.
