As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.
Hello,
Is this device cable of testing lmr400/lmr600 coax for distance to fault?
Frequency under test is 910-920mhz and distance to 250 feet.
Thanks,
Mike

It's a VNA so yes.

Yes, the TDR function of the NANOs is capable of finding faults along the
cable. Just use a frequency sweep appropriate to the length of cable.
Even though you are using the cable at nominally 900 MHz, the length for
appropriate TDR should be in the single-digit MHz range. At 250-feet,
possibly 5 MHz would be appropriate. For attenuation measurements, of
course, run the frequency sweep at the frequencies of interest.
