Episode 923
I make measurements and compare four different vector network analyzers
HP 8712 (801 cal points selected)
NanoVNA 2.8 (with latest firmware 0.8.0)
NanoVNA H4 (with dislord 1.0.64)
NanoVNA F-V2 (with sysjoint 0.3.0)
I measure a bandpass filter parameters S11 and S21. The same SOLT calibration set was used on each instrument.
Here are my thoughts:
HP 8712 - a joy to operate, large screen, very fast, simple user interface, up to 1601 cal points, 105dB dynamic range. 1.3GHz upper frequency
NanoVNA F-V2 - robust mechanical design, best dynamic range of the nanos. fast user interface. I wish there was dislord firmware for this model, 4.4 GHz upper frequency
NanoVNA H4 - Best bang per buck. the dislord firmware makes this a good choice. 1.5GHz upper frequency
NanoVNA 2.8 - outdated now, not recommended
