Hot on the heels of his beta 0.8 firmware release for the NanoVNA, DiSlord has followed it up with an additional beta firmware release which adds user selectable averaging via a "DISPLAY->BANDWIDTH" menu. Bandwidth can be set to 1 kHz, 300 Hz, 100 Hz, 30 Hz or 10 Hz. As any who has used a commercial VNA can tell you, using averaging can smooth out your data but at the expense of sl-o-o-owing down sweep rates. Truly no such thing as a free lunch.
Latest beta is located at . This is a preview of where the next edy555 firmware release is headed.
I thought there were no more tricks in the firmware developers bags to add more features to the limited flash space of the NanoVNA-H. That was t the main reason I begin gravitating towards the NanoVNA-H4 and NanoVNA-F. DiSLord's re-write and optimization of the NanoVNA's firmware, shows the NanoVNA-H is not quite ready to relinquish its crown. Looks like the -H4 and -F will be behind the curve until the upcoming edy555 firmware releases are ported to them.
Per DiSLord:
"When you drop below 1kHz, the scanning speed is significantly reduced, and the responsiveness of the menu drops, but is generally workable."
Also as previously noted, this beta firmware release is not for the NanoVNA-H4 or NanoVNA-F.
