The invention provides a method for accurately synchronizing frequency sweep between a scalar network analyzer and a signal generator, which comprises a signal generator and a scalar network analyzer.The signal generator is connected with the scalar network analyzer through a first BNC cable, a second BNC cable and a network cable, respectively. The method is specifically divided into the following steps: frequency sweep parameters are set on the scalar network analyzer, and each parameter is sent to the signal generator through the network cable; after receiving the frequency sweep parameters, the signal generator starts to sweep frequency, the signal generator sends scan starting / stopping signals to the scalar network analyzer through the first BNC cable, and the signal generator sendsa scanning pulse signal to the scalar network analyzer through the second BNC cable; the scalar network analyzer analyzes the scan starting / stopping signals and the scanning pulse signal sent out by the signal generator; the frequency sweeping process is constantly performed in the case of not changing the frequency sweep parameters. The method can realize synchronous measurement of the frequencysweep signal generator and the scalar network analyzer simply and accurately.
Description
technical field [0001] The invention relates to the field of synchronous frequency sweeping of scalar network analyzers and signal generators, in particular to a method for accurate synchronous frequency sweeping of scalar network analyzers and signal generators. Background technique [0002] The scalar network analyzer has the characteristics of low cost and simple operation. The scalar network analyzer cooperates with the frequency sweep signal generator to quickly and accurately perform transmission measurement, return loss and port VSWR measurement. Detectors, bridges and directional couplers can meet the testing needs of users in different frequency bands. [0003] The currently existing scalar network analyzer and frequency sweep signal generator sweep synchronization scheme is as follows: figure 1 As shown, the scalar network analyzer and frequency sweep signal generator are connected through 4 control lines to realize frequency sweep synchronization. [0004] Such ...
