Generator output power extremely low


 

My Tiny SA Ultra puts out a generator signal way lower than expected. As I keep reducing the output level, at some point it starts to get stronger on the connected receiver before disappearing below the noise way sooner than expected. I have tried it on several different receivers with the same result. I don't have another SA I can use to actually measure the output power level. I have been very careful to protrct the ports from static and always use attenuators between a transmitter and the SA port. The SA is a only a few weeks old so any suggestions as to what I might be doing wrong before I return it to the seller ? It passes all the self-tests fine.


 

At what output level does the output get stronger?

As the generator output power is decreased from the starting value of -17dBm, the signal level received drops into the receiver noise at around -30dBm and then at around -40dBm the signal level received on the directly connected receiver starts to come up out of the noise again but then it drops down again quickly by -50dBm or so generator setting. The receiver is fine and working normally with an antenna and I have detected this issue with 3 different receivers.


 

Suggest you contact your supplier as this is not easily to fix with some setting
