The new hardware increases the measured output power, and there is still a good dynamic when the frequency reaches 1.5GHz. The actual measurement is shown in the figure.
Latest firmware is V0.2.0 beta.
Firmware v0.2.0 beta update instructions:
1. Add data storage function, can save s1p, s2p files to SPI Flash in real time, which is convenient for offline analysis;
2. Adapt NanoVNA-Saver screenshot function, need to use [nanovna-saver-0.3.4-bh5hnu.exe] compiled by BH5HNU; you can get the new software from groups.io.
3. Support LCD backlight adjustment, adjustment range 1-100, default 75;
4. Revise the voltage display as the power display, support 8-level power display;
5. The calibration data interpolation uses the latest saved data instead of the default position of 0, which is more in line with operating habits;
6. Some UI optimizations such as Marker;
7. The maximum settable frequency can be expanded to 2.7GHz;
8. 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.
support measurable frequency to 1.5 GHz, default setting 1 GHz, accurate measurement up to 1.35GHz.
Product Description:
NanoVNA-F Mini Vector Network Analyser is a product based on the Open Source Project of NanoVNA (https://ttrf.tk/kit/nanovna/). The RF part is consistent with the original version (NanoVNA-F uses harmonic spread measurement frequency to 1.5 GHz ).
NanoVNA-F hardware functions include and are not limited to the following improvements:
1. Use 4.3-inch IPS TFT LCD screen, with a larger view angle and can be seen clearly in strong outdoor light.
2. Switch to large capacity 5000mAh lithium batter y, standby time is longer, and expand a USB interface. Usually, it can be used as a rechargeable treasure when the instrument is not used.
3. The IC is charged by high current 2A, and the charging time is shorter.
4. Change to larger and better operating wave wheel.
5. Switch to a power switch with a greater sense of operation and a better sense of operation.
6. Support Chinese and English menu switching;
7. Upgrade the user program by virtual U disk.
8. Standard aluminium shell to protect SMA head and reduce the interference of external electromagnetic wave to instrument.
8. Software open source github.com/flyoob/NanoVNA-F
The hardware block diagram of NanoVNA-F is as follows
NanoVNA-F measurement range is 50k-1.5GHz . The harmonic spread measurement frequency of the output signal of the clock chip SI5351 is 1000MHz. At 900M-1.5GHz, the dynamic range of S11 is 40dB (standing wave ratio is less than 1.02). At the same time, a metal shield is designed for the RF front-end, so that the dynamic range of S21 is better than 60dB in the whole frequency band.
