1. Antenna and Feeder Test Function:
Mainly used to measure and analyze the performance of microwave signal transmission lines such as antennas and feeders. It can detect key parameters such as electrical performance, mechanical performance and wireless transmission performance of antenna and feeder, such as reflection coefficient, standing wave ratio, spectrum distribution, transmission power and receiving sensitivity. These tests help to evaluate the loss and reflection of the feeder, analyze the quality of the feeder, quickly locate the cause of the fault, and provide basic data for optimizing network performance. Among them, the measurement range of FMT715C is 2MHz to 4.4GHz, and the coverage range of FMT760C is 2MHz to 6.1GHz.
Standing wave ratio (SWR/VSWR): Measures the voltage standing wave ratio, which reflects the impedance matching between the feeder and the antenna. When the matching is good, the standing wave ratio is close to 1, and the energy transmission efficiency is high. It is used to evaluate the performance of the antenna and feeder system and optimize the matching.
Return loss: A measure of how much the signal is reflected in the transmission line. High return loss means less signal reflection and high transmission efficiency. It is used to detect fault points in the antenna and feeder system and optimize transmission efficiency.
Phase: Measures the phase information of the signal, which is used to analyze the phase change during signal transmission. It is particularly important in antenna arrays and signal synchronization.
Impedance circle diagram (Smith chart): It intuitively displays the relationship between impedance and reflection coefficient, helping engineers to perform impedance matching and fault analysis. It is suitable for high-frequency and microwave circuit design.
Cable loss: Measures the energy loss of the cable when transmitting signals. Low-loss cables can improve the quality of signal transmission. It is used to evaluate cable quality and optimize network layout.

Field strength: measures the strength of the electromagnetic field, usually used in the fields of radio communication, electromagnetic radiation monitoring, etc. Assess the impact of the electromagnetic environment to ensure communication quality and personnel safety.
FM/AM demodulation analysis: demodulate and analyze frequency modulation (FM) and amplitude modulation (AM) signals to extract voice or data information. Widely used in broadcasting, communication and signal monitoring, it helps to analyze and understand the signal content.
ACLR (Adjacent Channel Leakage Ratio): measures the leakage power ratio of the signal in the adjacent channel. It is an important indicator for evaluating the performance of wireless communication systems, which helps to reduce interference and improve spectrum utilization efficiency.
3. Interference Analysis:
Mainly used to detect and identify interference components in the signal and analyze its characteristics. It can help users capture burst signals, find co-frequency interference, and accurately locate interference sources through technical means such as spectrograms and digital afterglow. The interference analysis function plays an important role in the maintenance and optimization of wireless communication networks, and can ensure communication quality and improve network performance. By timely identifying and processing interference, users can ensure stable signal transmission and reduce communication failures and interruptions.
Spectrogram: Displays the distribution of signals in the frequency domain and their changes over time. Through the spectrogram, users can intuitively observe the spectral characteristics of the signal, including frequency components, power distribution, and dynamic changes in the spectrum, which helps to identify and analyze interference signals.
Interference positioning: Use the built-in positioning function (options such as GPS and electronic compass may be required) to lock the location of the interference source. This function is particularly important in complex environments, and can quickly and accurately find the interference source, providing strong support for interference elimination.
Digital afterglow: A signal display technology that can retain the historical traces of the signal on the screen to form an afterglow-like effect. This allows users to more easily observe sudden, intermittent or periodic changes in signals, which is very effective for capturing and analyzing difficult-to-capture interference signals.
RSSI (Received Signal Strength Indicator): Received signal strength indicator, used to measure the strength of the received signal. In interference analysis, RSSI can help users understand the quality of the signal, determine whether there is interference and the intensity of interference, and is an important indicator for evaluating the signal environment and optimizing network performance.
Signal identification: Automatically identify the signal type based on the signal's spectrum characteristics, modulation mode and other characteristics. In interference analysis, the signal identification function can quickly distinguish useful signals from interference signals, providing convenience for subsequent analysis and processing.
Differential spectrum: Displays the difference between two or more signal spectra. In interference analysis, the differential spectrum helps to highlight the difference between interference signals and useful signals, helping users to more accurately identify and analyze interference signals.
