Well on mine the 30MHz fundamental is consistently at -35dBm. No problems with tests and all attenuator steps as well as the LNA do function as expected. TinySA Ultra (SeeSii) Version: tinySA4_v1.4-156-g4eb315d, still original.
Q: Does this indicate a problem, or was there a SW update that changed it to -26 dBm, Erik?
?
Thanks
