Erik,
? In some of the measurement examples you provided the frequency sweep starts at 0 Hz.? In peak search functions does the tinySA ignore the internal 0 Hz signal and start its search to the right of it??
? With the dc coupling (0 Hz) of the tinySA it looks like extra care has to be taken to ensure any signals with a dc component do not exceed both the ac and dc input limit of +10dBm without attenuation.
