What do you do when you have 3 VNAs on the workbench? You compare them of course!
Are NanoVNAs useable for typical hobbyist use, which is what they are intended for? Spoiler, it depends which one you get!
This is not intended to be a metrology-grade, quantitative video - but we still see some interesting and significant differences between the instruments.
ERRATA: In the video, I saw that the noise floor of the Siglent can be brought down by changing the sweep time. This is incorrect. However, the Siglent has the capability to average the measurements, which does bring down the noise floor by removing noise created by fast measurements.
