I hate windows and especially windows updates. After few updates, even great working computer becomes junk.
I have one vaio laptop, purchased 1998, never on the net, never updated, works as fast as when new. Got sony soundforge and othe audio software on it. Will never connect to net.
Got few expensive hp laptops, just few years old, top of the line, which after dozen windows updates barely work.

The DATS is a great tool, it is pretty much the only electronic gadget I rely on for building speakers. It is great for not only measuring raw drivers, but also the effects of an enclosure or crossover network.
As far as I am aware, the amplitude level in the generator mode does not affect the impedance analyzer mode. Your two graphs are scaled differently, but both appear to max out just over 50 ohms at 20KHz.
Also, the added mass is only used to determine the M(ms) and V(as) of the driver. The other T/S parameters can be found with a normal sweep.

I use rew with umic to design speakers. Generally i preffer 8 or 16 ohm speakers, had no need for impedance so far, but it looks like useful tool for sure. I am in learning phase.
Next two measurements are a little wild and i am not sure i can interpret all.
This is Phillips two domes combo, mid dome and tweeter. For some reason it dips below 4ohm, and fs is rather weird. It comes with built in cossover, maybe thats the reason.
But they do measure well and sound fine.

Last for today, its nice outside.
This is great sounding open baffle based on 4 paper cone aura midranges (they do not classify as fullrange). Fs is 170Hz as measured before.
Added are two Monsoon planar tweeters. Impedance is 4ohm.
With woofers below 100Hz this is great sounding combo.

User error. My desktop W10 install is 6 years old and has been through 3 CPU/motherboard upgrades. With my browser open and ~200 processes running, CPU toggles between 0-1% utilization, and disk utilization is 0%.

Old machines can't process updates efficiently, so it seems like resources are constantly being hogged. It's a self-inflicted problem to keep using an ancient dual-core CPU with Windows 10/11.
The scale on the screen is 2 to 5 ohm, quite a zoom.
Well, it is what it is. I just measure.
Dave, have you ever received that simple active crossover i sent you?
