4. Panduan Persediaan

4.1 Pengecasan Awal

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 Menghidupkan/Mematikan

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. Operasi

5.1 Navigasi Antara Muka Pengguna

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 Penentukuran

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 Mod Pengukuran

The device supports various measurement modes, including:

• S11 (Pekali Pantulan): Measures the reflection characteristics of a device connected to PORT 1. Useful for SWR, Return Loss, and Smith Chart analysis.
• S21 (Pekali Penghantaran): Measures the transmission characteristics between PORT 1 and PORT 2. Useful for gain/loss and phase measurements of filters, amppenyelamat, dll.
• SWR (Standing Wave Ratio): Indicates the impedance match of an antenna or transmission line.
• Smith Chart: Graphical representation of complex impedance.
• Fasa: Displays the phase response of the DUT.
• Group Delay: Measures the time delay of signals through the DUT.

5.4 Kesambungan Perisian PC

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. Penyelenggaraan

6.1 Pembersihan

Gunakan kain lembut dan kering untuk membersihkan peranti. Untuk kotoran degil, gunakan sedikit kainamp cloth can be used. Avoid using harsh chemicals or abrasive materials, as they may damage the screen or casing.

6.2 Penyimpanan

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 Penjagaan Bateri

To prolong battery life, avoid fully discharging the battery frequently. If storing for an extended period, charge the battery to approximately 50% and recharge every few months.
