Transmit phase noise


I’ve been testing my LimeSDR for phase noise at 850 MHz, primarily because it is listed in the LMS7002 specs so I can compare.

I’m seeing -89 dBc/Hz. If I read the spec sheet correctly, I should see about 10 dB less or -99 dBc/Hz.

I’m using LimeSuiteGUI to generate the carrier. Can anyone on the design team comment? I must be missing a setting in LimeSuiteGUI?
