Doh!! I just installed NanoVNA-H__900_aa_20191003.dfu for hacking a new menu tree

If you calibrate the touchscreen, it will lock-up at boot.?Please confirm.? On Fri, 4 Oct 2019 at 7:59 PM, in3elx@...<in3elx@...> wrote: I installed the NanoVNA__800_aa_20191003

I installed the NanoVNA__800_aa_20191003 firmware. I think this is fine, it has improved to 300Mhz ...

Since I want to use my NanoVNA/P, I doubt that I will use your software for now. But it had crossed my mind that perhaps look at modifying it later - once your rapid development had slowed.

@in3elx The latest build code is 10KHz-1.5GHz

Yes, "Return Loss" s o m e t i m e s is a misnomer: If used in context with simply two different impedances meeting at a connection. This can be understood as a complex generator's inner (serial)

Any .dfu installed becomes the only firmware, replacing previously installed firmware. I know of none. No real benefit, since reflection bridge components are fixed for 50 Ohms. Firmware based on

Steven Maas if I recall in one of his little texts, mentions, I dis like the term return loss. Its one of those EE crazy terms! That said, I never discuss return loss with any thought whatsoever. All

Correct. The measurement conducted is a SPOT NOISE FIGURE measurement. The VNA or a SA may be set into the CW or fixed frequency receive mode. If you desire a swept NF measurement, than perhaps steps

Thanks for all these info, compliments. This interests me: "DMR_M_10KHz_sept-13-19.dfu Such as these were for enhancements, in this case 10KHz instead of 50KHz minimum. I >>guess<< many enhancements

I looked for BNC with 0.1" spacing, but so far found only this: http://daqstuff.com/500057_brd_bnc_conn_kit.htm

Need to place the file with the electrical circuit separately. Some do not suspect that it is in the instruction manual. Many questions will disappear.
