TinySA High Output??

 

I noticed that when I have the original TinySA the LOW IN mode, the unit is outputting a random freq signal from the HIGH IN SMA.

I am not exactly sure what it is, I have all of the OUTPUT settings off.

Any ideas?

Any way to stop it?

Correct.
You leakage from the sweeping LO

Thanks, would it hurt to place a 50ohm terminator on the SMA to lower the level?

Rich,
Is it possible you turned on the LO Output option?? (It is in the CONFIG/EXPERT CONFIG menu).
With LO Output enabled I get about 10dBm of Local Oscillator at the HIGH connector.? With it disabled I get around -17dBm feedthrough at the HIGH connector when the Low input center frequency is set to 200 MHz (LO is then 633.8 MHz).
