4.1 Početno punjenje

Before first use, fully charge the NanoVNA-F V3.1. Connect the provided USB Type-C cable to the device's USB-C port and the other end to a standard USB power adapter (5V, 1A recommended) or a computer's USB port. The charging indicator will show the charging status.

4.2 Uključivanje/isključivanje

Locate the power switch on the side of the device. Slide the switch to the "ON" position to power on the unit. To power off, slide the switch to the "OFF" position.

4.3 Connecting to a Device Under Test (DUT)

The NanoVNA-F V3.1 has two SMA ports: PORT 1 (S11) and PORT 2 (S21). Use the provided SMA cables and adapters to connect your DUT. For reflection measurements (S11), connect the DUT to PORT 1. For transmission measurements (S21), connect the input of the DUT to PORT 1 and the output to PORT 2.

5. Operacija

5.1 Navigacija korisničkim interfejsom

The NanoVNA-F V3.1 features a resistive touch screen and a wheel button for navigation. Use the stylus or your finger to interact with the touch screen menus. The wheel button can be used for fine adjustments or menu selection in some modes.

5.2 Kalibracija

Calibration is crucial for accurate measurements. Perform a full two-port calibration (OPEN, SHORT, LOAD, THRU) for the desired frequency range before taking measurements. Access the calibration menu from the main screen.

1. Connect the OPEN standard to PORT 1 and perform the OPEN calibration.
2. Connect the SHORT standard to PORT 1 and perform the SHORT calibration.
3. Connect the LOAD standard to PORT 1 and perform the LOAD calibration.
4. Connect PORT 1 and PORT 2 directly using a THRU cable and perform the THRU calibration.
5. Save the calibration data.

5.3 Načini mjerenja

The device supports various measurement modes, including:

• S11 (Reflection Coefficient): Measures the reflection characteristics of a device connected to PORT 1. Useful for SWR, Return Loss, and Smith Chart analysis.
• S21 (Transmission Coefficient): Measures the transmission characteristics between PORT 1 and PORT 2. Useful for gain/loss and phase measurements of filters, ampliferi itd.
• SWR (Omjer stojnih valova): Indicates the impedance match of an antenna or transmission line.
• Smith Chart: Graphical representation of complex impedance.
• faza: Displays the phase response of the DUT.
• Group Delay: Measures the time delay of signals through the DUT.

5.4 PC Software Connectivity

For advanced analysis and data logging, connect the NanoVNA-F V3.1 to a PC using the USB Type-C cable. Download and install compatible software like NanoVNA Saver. This software allows for larger display, detailed analysis, and export of Touchstone (.snp) files for use in other RF simulation tools.

6. Održavanje

6.1 Čišćenje

Za čišćenje uređaja koristite meku, suhu krpu. Za tvrdokornu prljavštinu, laganoamp cloth can be used. Avoid using harsh chemicals or abrasive materials, as they may damage the screen or casing.

6.2 Skladištenje

When not in use, store the NanoVNA-F V3.1 in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case to prevent physical damage.

6.3 Njega baterija

Da biste produžili vijek trajanja baterije, izbjegavajte često potpuno pražnjenje baterije. Ako je skladištite duži period, napunite bateriju do otprilike 50% i punite je svakih nekoliko mjeseci.
