Considering the price difference between the tinySA and the Siglent is
about 14dB, I don't expect equal performance.

I just want to see how close they are.

Similar comparisons with the nanoVNA and high end VNA's were a real eye opener.
Dick,
? ?Nice dB comparison.? I also continue to be surprised by how functional the NanoVNA-F, NanoVNA-H4 and SAA2 are in comparison to their price.? I have a couple of higher end spectrum analyzers too, but a lot of my work is at HF so the tinySA is becoming more and more the first one I reach for in that range.
? I've always wanted a portable frequency response measurement device that worked above 100MHz that I could carry in my pocket when I attended swapfests.? The tinySA fits that bill with its built in calibrator output and LOW input.? I can't wait for hamfests to start back up in my county after this COVID-19 crisis subsides so I can head for the bargain tables and cherry pick items ;)
? The LOW input is where the tinySA shines because of its adjustable attenuator and filtering.? The HIGH input is wide open and without an external attenuator is prone to producing spurious signals.?
? The LOW output produces sinusoidal waveforms up to 350MHz. The output can be swept over a selected span within that range.? The output can also be AM or FM modulated and level swept from -6 to -76dBm.? I would have been intrigued by the device if only for its LOW output features.
