The zero hertz peak is indeed ignored
The tinySA does not have DC coupling. Below 100kHz it starts to roll off and at 10kHz there is about 8dB attenuation which is not compensated. The input capacitor is 1 microF

Thanks for the clarification Erik,
? ?The "
0 MHz to 350MHz" specification on the Wiki page threw me off.? I think the HP 8566 series spectrum analyzers were specified? down to 30 Hz but using them at less than 3 times the power line frequency was a more practical lower limit.? That and a rbw that was low enough to be useful without bumping into the 1rst LO leakage peak.
? ?I'll make a mental note of the 1uF coupling capacitor.? An un-attenuated lower limit of 100 kHz should be more than sufficient for the majority of prospective tinySA buyers.
