Yes, the TinySA is a spectrum analyzer. The NanoVNA is a network analyzer. The NanoVNA can be used to measure impedances of coax, the rate of loss of coax over a frequency range, SWR. It has a TDR function. It can be used to measure values (resistance and reactance, impedance) of inductors, capacitors, resistors. It can be used to measure the response curves of filters. It can be used to measure the gain and frequency response of preamps, amplifiers, etc. The TinySA is not meant to do any of these things.

The TinySA may give you a glimmer of loss of coax, but it won't be as accurate as the NanoVNA. It certainly doesn't have a TDR function. But it can tell you if a circuit is oscillating, or if it has spurious signals. It can tell if there are outputs at harmonics of an amplifier. It can tell you what RF signals are present in an area. I have a couple microwave circuits that use copper pipe caps as bandpass filters. The circuits are frequency multipliers. The TinySA is very useful to make sure I have the pipe cap filters tuned to the correct harmonic of the input, and used to peak the signal at that frequency.
