Features:
- With DC dimming method, 4" full-view LCD screen can be seen more clearly for outdoor uses, and more comfortable for indoor uses.
- Optimized Electric Bridge: Making full use of the harmonics of Si5351, it can use the 5th harmonic to measure up to 1.5GHz.
- When fundamental wave is used, the output level of CH0 is increased to 0dBm, making reflection measurement more accurate.
- Solved the abnormality of NanoVNA-H when operating at around 6MHz before.
- Redesigned power management circuit reduces power noise, USB power interference, and charging current.
- Improved PCB layout.
- Reserved UART interface for DIY expansion.
- Lightweight ABS shell keeps the device well protected.
-Computer software supports control and real-time display. And it support for exporting snp files for various radio design and simulation software.
- As a measuring device, accuracy is of great importance. Simple calibration parts are included in the package. We have calibrated the product"s dual ports before delivery. When your measurement conditions change (for example, switching from a narrower calibration bandwidth to a wider measurement bandwidth with an extension cable measurement), you need to re-calibrate. After calibration, it is saved as setting 0, which can be used directly at the next boot, or it can be saved to the other 4 saved items through recall when needed.
Parameters:
1. ABS Shell: 75mm x 133mm x 18mm (excluding protrusions)
2. Measurement Frequency: 50KHz ~ 1.5GHz
3. RF Output: 0dbm (± 2dB, fundamental wave)
4. Frequency Accuracy: <2ppm
5. Frequency Stability: <0.5ppm
6. Measurement Range: 70dB (50kHz-300 MHz), (60dB (300M-900MHz), 40dB (0.9G-1.5GHz) enable expansion firmware)
(Note: Please pay attention to the error caused by nonlinear transformatiion of the fundamental wave when using harmonic measurement.)
7. Port SWR: <1.1
8. Display: 4" TFT (320 x 480)
9. USB Interface: USB type-C; Communication Mode: CDC (serial)
10. Power Supply: USB 5V 200mA. Maxmum charging current 1A
11. Number of Calibration Points: 101 (fixed)
12. Number of Scanning Points: 101 (fixed)
13. Display Tracking: 4, Marking: 4, Save Setting: 5
14. Measurement of S-parameters, voltage standing wave ratio, phase, delay, Smith chart, time domain analysis, etc.

    Really valuable instrument, with lot of options for the price. A single BIG defect, luckily quickly solved googling around: the touch screen responds randomly, sometimes by its own, sometimes not reacting to taps. I discovered that the plastic box is slightly thick and "pushed" the touch screen on the side. Putting four plastic washers between the two halves of the enclosure at the screws and screwing back all, solved the problem.

    Shipping is super fast as usual. Packaging is OK, but plastic could not protect the paper box (which is nice, but not very practical).

    As I have an older NanoVNA-F I can compare H4 with it.
    H4:
    Electrically it's better without hesitation. It has no trouble to keep everything below -60dB till 900MHz, and -50dB till almost 1.5GHz. This is really impressive.
    It's lighter due to plastic case (I regard this as a positive thing).
    LCD size is a bit smaller than F, but as there is no scale it looks almost the same.
    LCD visibility (especially from SMA side) is slightly worse than F.
    Touch reliability is slightly worse than F.

    Pushable rotating knob is still nothing to write home about but it seems to work.

    So far I could not locate a new SW version (I mean binary as I'm not keen compiling it myself). In addition the menu cheat sheet contains a DFU menu that is not found on the actual menu of the SW... So it's unclear to me how firmware update supposed to be done if it's necessary.

    In overall it's light and electrically so far the best package (it's a very good value). I look forward seeing the V2 variant with a similar size display.
