Vector network analyzer LiteVNA 64

Order the LiteVNA64 vector network analyzer - choose professional analysis in a compact package!

Vector network analyzer LiteVNA 64 is a modern measuring instrument for radio frequency devices. It allows you to analyze the parameters of antennas, filters, cables and circuits. You can fine-tune your equipment to operate at the desired frequencies. This device is indispensable for the development and debugging of radio electronics. Its capabilities were previously available only in expensive laboratory instruments.

This device uses the vector measurement method. It measures not only the amplitude of the signal, but also its phase. This gives a complete picture of the behavior of the device under study. You will see how your antenna or filter behaves in the real frequency range. It is a key tool for achieving maximum efficiency in wireless systems.

• Wide frequency range for analyzing most modern devices.

• Vector measurements amplitudes and phases for complex analysis.

• Portability and autonomy from a computer with its own display.

• Intuitive interface and support for the Russian language in the software.

• Great value for money for amateurs and professionals.

How does this network analyzer work?

The device generates a test signal of known frequency and amplitude. It supplies this signal to the input of the device under test (for example, an antenna). The analyzer then measures the signal reflected and transmitted through the device. By comparing them with the original signal, it calculates complex coefficients. These coefficients show how the device affects the signal.

Based on this data, graphs and parameters are built. The most famous graph is the SWR (SWR, or SWR). It shows how well the antenna is matched to the transmitter. Reflectance (S11) and transmission (S21) are also measured. This allows you to see the bandwidth of the filter or the resonant frequency of the antenna. You get digital data and visual graphs.

Technical characteristics and scope

LiteVNA 64 has impressive parameters for its class. The operating frequency range is usually from 50 kHz to 6.4 GHz. The dynamic range can reach 80-100 dB. Frequency resolution is very high for detailed measurements. The device has two ports for connecting devices under test. It can work both independently and in conjunction with a computer.

The functionality includes all the main modes of the vector analyzer. Measurement of S-parameters (S11, S21, S12, S22) for two-port devices. Plotting graphs of SWR, impedance, reflection coefficient in polar coordinates. TDR mode (time domain reflectometry) for searching for breaks in cables. Calibration with calibration load kit for improved accuracy.

This device is critical for FPV developers and enthusiasts. It can be used to fine-tune the video transmitter antenna for maximum range. Check the workmanship or coordination of the homemade antenna. Analyze and tune bandpass filters to suppress interference. Diagnose problems in coaxial cables and connectors.

The device is compact and can be used in the field. For example, for quick testing of antennas right on the airfield. Autonomous battery operation makes it completely mobile. A simple interface allows you to quickly get the necessary data. Detailed analysis can be carried out by connecting the device to a computer via USB.
