Now all correct, also i speedup SPI bus, display update should be very fast

DiSlord,
Bandwidth option seems to be working. I have attached a screenshot showing a 1 kHz BW and 100 Hz BW LOGMAG display (10 kHz - 2 GHz). The noise floor for the 100 Hz BW is noticeably lower.
The SPI bus speedup also is noticeable. The NanoVNA-H4 display update rate is faster than both the NanoVNA (v0.7.1) and NanoVNA-F (v0.1.1) when using the normal 1 kHz BW.
Hope your NanoVNA-H4 arrives soon and maybe 201 pts can be added to the firmware.
Regards,
