Safe measurement of the output of transmitters

For best measurement of harmonics in the output of transmitters the input level of the tinySA should aim between -20dBm and -10dBm.

Required attenuation between transmitter and tinySA.

The best approach is to use ALWAYS a 30 dB attenuator directly connected to the tinySA and to use power attenuators to reduce the output of the transmitter to the target input level of this 30 dB attenuator, that is +10 dBm.

So you will need these power attenuators.

Another option is to use a dummy load and an inline 50 dB attenuating sampler. A nice example of how to build one yourself can be found here (PDF).
