Note1:

  Values have been obtained by applying the test system as per Fig. 1. 

Note2:

  The RF emission measure  has been obtained by connecting the spectrum analyser directly to RX Pin 3. 

Note3:

  By switch-on time is meant the time required by the receiver to acquire the declared characteristics from the very moment the 

power supply is applied. 

Note4:

 Values obtained with 10K

 maximum load applied.
