LO leakage as a function of TX power

Hi, I plan to use PicoZED SDR as a simple signal generator. I wonder how the LO leakage behaves as a function of transmitted signal power? For example, what can be seen at the transmitter output connector at LO frequency when the baseband signal is totally off? The frequency would be around 1.4GHz.

"how the LO leakage behaves as a function of transmitted signal power?"

The analog devices EngineerZone is the place to ask questions about AD9361 performance.

AD9361 performance may be the largest contributor to leakage, however part of the leakage is caused by parasitics which depend on the board design, I think. So I would be happy if someone would plug a spectrum analyzer to the TX connector, set the signal amplitude to zero and see how much power is transmitted on the LO frequency :)
Thanks!
