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.
