I guess if I have to go to soem hard to access space to take measurements I
would not be happy to rely on pause button. I would like to make snapshot that
survives even turning device off. Also, when I am there I might need to make
several measurements, for example to check several antennas or cables, or
simply to chech cable and antenna independently.
it is possible to store data in the program flash of the controller. But each record needs 2 kB flash memory and write resource of this flash memory is limited.
STM32F072CB used in the NanoVNA has just 128 kB flash memory and it can perform 10000 write cycles. It means that after 10000 save operations, you will needs to replace STM32F072CB chip with a new one.
