4 Measure the Conducted Output Power

  1. Disconnect the antenna and perform conducted measurements at the SMA connector or solder on a semi-rigid coax cable at the 50 Ω point.
  2. Preferred: Use a Spectrum analyzer. MSP-SA430 or similar does not have the required accuracy. Use 1 MHz RBW for measuring output power and unmodulated carrier on the transmitter.
  3. If a SA is not available, then use an EM or Launchpad with a SMA connection point.
    1. Add a known RF attenuation block between the transmitter’s SMA connector (50 Ω point) and the EM/Launchpad connector.
    2. Use SmartRF Studio and set the EM/Launchpad in continuous RX and read the RSSI.
  4. If the conducted power is poor:
    1. Is the schematic according to the reference design?
    2. Is the layout according to the reference design?
