4. Operating the NanoVNA-H4

4.1 ഉപയോക്തൃ ഇന്റർഫേസും നാവിഗേഷനും

The NanoVNA-H4 features a 4-inch touch-sensitive LCD display for interaction. Navigate through menus and settings by tapping on the screen. A stylus is included for precise input.

Figure 4.1: The NanoVNA-H4's 4-inch display supports touch input. Key features include 10KHz-1.5GHz frequency range, USB connectivity, 1950mAh battery, and Hardware Version 4.3.

4.2 കാലിബ്രേഷൻ

Calibration is crucial for accurate measurements. It should be performed whenever the frequency range is changed. The calibration status will be displayed on the screen. Use the provided OPEN, SHORT, and LOAD calibration standards.

1. Connect the appropriate calibration standard (OPEN, SHORT, or LOAD) to the NanoVNA-H4's port.
2. Follow the on-screen instructions to perform the calibration steps.
3. Once calibration is complete, the status display will show 'CnDRSTX', where 'n' indicates the data number being loaded.

4.3 അളവ് പരാമീറ്ററുകൾ

The NanoVNA-H4 can measure various S-parameters:

• S11 (Reflection Measurement): Measures the reflection coefficient of a device.
• S21 (Transmission Measurement): Measures the transmission coefficient between two ports.

For S12 and S22 measurements, the transceiver port wiring needs to be manually swapped.

4.4 PC Control with NanoVNASaver

The NanoVNA-H4 can be connected to a computer via the USB Type-C cable to use the NanoVNASaver software. This software allows for data extraction, display on a larger screen, and saving data to Touchstone (.snp) files for further analysis and simulation.

5.1 Preparing the RF Demo Kit

1. Connect the two 20cm SMA to IPEX adapter cables to the NanoVNA-H4 (or NanoVNA-F, as shown in some diagrams).
2. Before testing specific circuits on the board, recalibrate your NanoVNA-H4 using the calibration circuits (13 Short, 14 Open, 15 Load, and 16 Thru) located on the RF Demo Kit itself. Save these parameters to SAVE 0 on your device.

5.2 ഫങ്ഷണൽ മൊഡ്യൂളുകൾ

The RF Demo Kit includes modules for testing various components and circuits, such as:

• 30MHz short wave low-pass filter (LPF)
• 100MHz FM high-pass filter (HPF)
• 433MHz common SAW band pass filter (BPF)
• 6.5MHz ceramic trap (BSF)
• Attenuators (-10dB, -3dB)
• RLC series-parallel circuits

7. പ്രശ്‌നപരിഹാരം

7.1 പൊതുവായ പ്രശ്നങ്ങളും പരിഹാരങ്ങളും

• ഉപകരണം ഓണാക്കുന്നില്ല: Ensure the battery is charged. Connect the USB Type-C cable to a power source and try again.
• കൃത്യമല്ലാത്ത അളവുകൾ: Perform a full calibration using the provided OPEN, SHORT, and LOAD standards. Ensure cables are securely connected and not damaged. Recalibrate if the frequency range is changed.
• SD card not recognized: Ensure the MicroSD card is inserted correctly. Verify that it is a low-speed, SPI mode compatible card. Try formatting the card (this will erase all data on the card).
• No display or flickering screen: Recharge the device. If the issue persists, contact customer support.
• PC software (NanoVNASaver) not connecting: Ensure the USB cable is properly connected. Install the necessary drivers if prompted by your operating system. Restart both the NanoVNA-H4 and the computer.
