NanoVNA-F Firmware 0.2.1

Firmware v0.2.1 release

• The fundamental output power can be adjusted in four levels. When measuring low resistance components, setting a small output power can prevent the mixer input from overloading;
• Display the current VF parameters in TDR and eDelay modes;
• Add the format quality factor trace display.
  
  
  

NanoVNA-F Firmware 0.2.0 beta

Firmware v0.2.0 beta update instructions:

• Add data storage function, can save s1p, s2p files to SPI Flash in real time, which is convenient for offline analysis;
• Adapt NanoVNA-Saver screenshot function, need to use nanovna-saver-0.3.4-bh5hnu.exe compiled by BH5HNU;
• Support LCD backlight adjustment, adjustment range 1-100, default 75;
• Revise the voltage display as the power display, support 8-level power display;
• The calibration data interpolation uses the latest saved data instead of the default position of 0, which is more in line with operating habits;
• Some UI optimizations such as Marker;
• The maximum settable frequency can be expanded to 2.7GHz;
• Two different sets of gain tables are used for hardware V2.2 and hardware V2.3&V3.1, please be sure to select the corresponding firmware to upgrade, please consult your seller for how to check the hardware version;

Important hint !

This firmware is only applicable to NanoVNA-F machines manufactured by BH5HNU.
Any third-party NanoVNA-F hardware has not been tested, and any problems with third-party hardware using this firmware will not be explained by BH5HNU. Thank you for your cooperation.

NanoVNA-F Firmware 0.1.5

This firmware is only for HW2.3 HW3.1

1. Calibration data interpolation uses the latest saved data instead of the default position of 0, which is more in line with operating habits.
2. No new features were added compared to firmware v0.1.4.
   

NanoVNA-F Firmware 0.1.4

1. Supports 0dBm output (fundamental frequency, for HW V3.1 & HW V2.3 only, for HW V2.2 still -13dBm output).
2. No new features were added compared to firmware v0.1.1.

And all of our NanoVNA-F machines come with a serial number.

Difference between different versions.

NanoVNA-F Firmware 0.1.1

1. Fixed SWR axis display error.
2. Fixed grid display problems.
3. Modify boot logo.

NanoVNA-F Firmware 0.1.0 !

Hello everyone, we have just released NanoVNA-F firmware 0.1.0.

1. Add TDR feature
2. Add marker tracking feature & dynamic update of frequency and other information when the mark moves
3. Add ordinate display
4. Support to 10kHz frequency
5. Some font, color, and layout optimizations
6. suggestions from groups.io/nanovna-f & facebook group members and much more, thank you for your feedback
   (1) a beep to the end of each standard measurement in calibration
   (2) callsign.txt not limited to call sign display, can display your phone and email address, etc.

The startup information is not displayed for a long time at present, you can call it up in the menu.
Just into the menu: CONFIG -> ABOUT

Support measurable frequency to 1.5 GHz

1. support measurable frequency to 1.5 GHz, default setting 1 GHz, accurate measurement up to 1.35GHz.
2. fix: unexpected 0.3dB offset of s21 in thru
3. fix: mark all off bug
4. fix: clutter display when standing wave ratio is infinite
5. add version & info command
6. add REAL IMAG R X trace format

Display call sign at startup

• 呼号显示 / Can display call sign
• 修复 100MHz 频点不输出的 BUG / fix BUG: CW=100MHz do not output
• 优化中文翻译 / Optimize Chinese translation

support NanoVNA's PC software

1. change command prompt from "nanovna-F>" to "ch> " to support NanoVNA's PC software.
2. Freq < 100M, Si5351 only use PLL_A as output. Increase delay when si5351 reset pll.
3. Add beep on boot.

First release.
