NanoVNA-F "Handheld Vector Network Analyzer"
is
a product based on the Open Source Project of NanoVNA
(
https://ttrf.tk/kit/nanovna/
).
Thanks to hugen's creative idea of use the harmonic of Si5351
, We build NanoVNA-F and expand the measure frequency up to 1GHz, which S11 still have 40dB dynamic range At 1GHz.
Or watch the Video:

NanoVNA-F hardware features include and are not limited to the following improvements:
1.
Use 4.3-inch IPS TFT LCD & resistive touch screen
, with a larger view angle and can be seen clearly in strong outdoor light.
2. Switch to large capacity
5000mAh/3.7V lithium battery
(The battery is an optional accessory, some
International express
cannot transport the battery, we also provide a battery holder, you can use the common mobile phone battery as an alternative, which size limit < L(90mm)*W(54mm)*H(5.6mm)),
standby time is longer, and expand a USB interface. Usually, it can be used as a power bank when the instrument is not used.
3. The Lipo Charing IC to changed to IP5306(with 2A
high charing current)
, make the charging time shorter.
4. Use a larger and better operating level.
5. Use a larger and better operating Power Switch.
6. Support Chinese and English menu switching;
7. Upgrade the user program by virtual U disk（16MB SPI Flash Memory Inside）.
8. Standard aluminium shell to protect SMA head and reduce the interference of external electromagnetic wave to instrument.

NanoVNA-F hardware block diagram:
The NanoVNA-F measurement range is 50k-1GHz. Use the harmonic of the clock chip SI5351 the
measure
frequency up to 1000MHz. At 600M-1GHz, the S11 has a dynamic range of 40dB (the standing wave ratio is less than 1.02). The RF front end is designed with a metal shield that allows the S21 to have a dynamic range better than 60dB over the full frequency range.
Basic performance:
● Size: 14CM * 7.5CM * 2CM (length, width and height)
● Measurement frequency: 50kHz ~ 1000MHz
● RF output: -13dbm (maximum -9dbm)
● Frequency accuracy: < 0.5ppm
● Port SWR: < 1.1
●
Display: 4.3 inch IPS TFT (800x480)
● USB interface: USB Type-C communication mode: CDC (serial)
● Power consumption: USB 5V 200mA, built-in 5000mAh/3.7V battery, theoretical battery life 18 hours, maximum charging current 2A
● Output capacity: 5V/1A, support for Android, Apple mobile phone
● Number of calibration points: 101
● Number of scanning points: 101
● Display Tracking: 4, Marking: 4, Setting Save: 5
● Scanning time: about 1.9s/1 times (50kHz ~ 1000MHz full frequency band)
Can measure S parameters, voltage standing wave ratio SWR, phase map, group delay, Smith chart...

1, NanoVNA-F S11 parameters, SWR standing wave ratio measure:
WOUXUN UV9D-Plus antenna UHF standing wave ratio measurement, starting frequency: 300M, stop frequency: 600M, the green curve in the figure below is the standing wave ratio, the lowest frequency of the standing wave is at 444.000000MHz, SWR=1.03.
WOUXUN
UV9D-Plus antenna interface is an SMA standard male (internal screw) that can be directly connected to the instrument or connected via the included SMA elbow for easy testing.
Baofeng UV-5R VHF antenna VSWR measurement, the antenna interface is SMA standard female, can be connected to the instrument through the attached SMA-JJ adapter. The lowest point of the standing wave is 134.200000MHz, SWR=1.68.
2, S21 insertion loss measurement, low pass, high pass, band pass filter measurement

4、Package list
● NanoVNA-F x1
● SMA-JJ RG316 cable 20CM x2 (
NanoVNA-F is a standard SMA female connector, external screw inner hole, use this cable to switch to M head, N head to better protect SMA female
)
● 1 set of calibration parts (
50Ω standard load x1, sma open x1, sma short x1, use the included calibration piece, the instrument can be calibrated to get good measurement result data, the instrument has been fully frequency-calibrated before shipment and Store the data in parameter 0. If you change the measurement conditions, such as adding a patch cord and modifying the frequency range, you may need to recalibrate and store the parameters in 0-4. All parameters can be called up by the “recall” function.
