I am finally understanding the concept of calibrations and saving the settings/range in the nanoVNA. But I am wondering if there is any way to save results from out in the field and then recall/display them later, without having to drag a PC around with it. Or maybe that should go on a "wish list" for a firmware update.

there is no memory on the board to store results.

Bruce,

You could calibrate the device, make the measurement of interest, go to "Stimulus", press "Pause Sweep", and the data is saved in the nanovna. The device under test can be removed and the data is preserved in the nanovna. Unfortunately, I don't seem to be able to get the serial port to work once the nanovna is connected to a computer without resetting the device which drops all of the data.

Does anyone have a cell phone application that will read data from the nanovna using an On-The-Go cable? If so, this method could bring the data into the cell phone where it could be saved.

nice trick, but it will works until power off...

the smartphone solution NanoVNA -webclient would be the solution but for me i get the nice graphs and possible saving of S1P etc but connection with nao fails.
I haven't seen any progress so far.Search messages.
