The role of the tracking generator option of the handheld spectrum analyzer
The handheld spectrum analyzer is mainly used to discover and measure the characteristic parameters of the RF signal such as amplitude and frequency, and can be applied to wireless communication, electronic testing and fault diagnosis. The tracking generator option is a swept frequency signal generator synchronized with the spectrum analyzer scanning receiving frequency. It can automatically adjust the frequency of its output signal in real time and accurately follow the tuning frequency changes of the spectrum analyzer to achieve adaptive swept frequency measurement. The following is a detailed description of the role of the tracking generator option of the handheld spectrum analyzer:
1. Real-time adaptive swept frequency measurement
A major feature of the tracking generator option is that it can automatically adjust the frequency of its output signal in real time following the tuning frequency changes of the spectrum analyzer. Therefore, during the measurement process, engineers can obtain continuous and accurate spectrum data without manually adjusting the frequency. This feature improves test efficiency and makes the handheld spectrum analyzer more convenient in field applications.
2. Observe the stimulus response characteristics of the DUT
By connecting the output of the tracking generator to the input of the DUT, and then connecting the output of the DUT to the spectrum analyzer, engineers can intuitively observe the response characteristics of the DUT at different frequencies, such as gain, phase change, etc. This provides strong support for frequency response analysis, allowing engineers to have a deeper understanding of the performance of the DUT.
3. Measure the insertion loss of the network or device
Insertion loss is an important indicator for measuring the energy loss of a signal when passing through a network or device. By using the combination of a tracking generator and a spectrum analyzer, engineers can easily measure the insertion loss of a network or device. By comparing the power level of the signal before and after passing through the DUT, the insertion loss value can be accurately calculated. This is of great significance for evaluating the efficiency of the signal transmission path, optimizing the network layout, and troubleshooting.
4. Achieve a certain degree of scalar network analysis
The combination of a tracking generator and a spectrum analyzer can achieve a certain degree of scalar network analysis, such as the measurement of the S21 parameter (without considering phase information). This is very useful for scenarios such as rapid evaluation of network characteristics and fault diagnosis. In a handheld spectrum analyzer, this function provides engineers with a convenient network analysis method.
5. System calibration and verification
During the construction or maintenance of the RF system, the tracking generator can be used for system calibration and verification. By simulating the actual signal source, check whether the response of each part of the system meets expectations, and ensure the stability and accuracy of the system performance. This is essential to ensure the normal operation of the wireless communication system and avoid potential interference.
In short, through real-time synchronous measurement, DUT response analysis, insertion loss measurement, and system calibration and verification functions, the tracking generator option plays an important role in wireless communication network optimization, radio monitoring, electromagnetic compatibility testing, and filter adjustment and testing.
