The invention discloses a band-segmented frequency sweeping device and a signal generator having a band-segmented frequency sweeping function. The band-segmented frequency sweeping device comprises an input module, a display module, a counting module, and an output module. The input module is used for inputting N groups of frequency sweeping parameters and each group of frequency sweeping parameters at least includes hopping time, frequency sweeping time, a starting frequency, and an end frequency, wherein the N is an integer larger than or equal to 2. The display module is used for displaying the N groups of frequency sweeping parameters. The counting module is used for generating N frequency-band switching signals in sequence according to a work clock and N hopping time. The output module is used for outputting N segments of frequency sweeping signals in sequence according the N frequency-band switching signals and the N groups of frequency sweeping parameters. Compared with the prior art, the provided band-segmented frequency sweeping device enables a plurality of segments of frequency sweeping signals to be outputted by setting multiple groups of frequency sweeping parameters at one time. Moreover, each group of parameters can be set randomly according to demands. Therefore, application becomes flexible.
Description
technical field [0001] The invention relates to the field of test and measurement, in particular to a segmented frequency sweep device and a signal generator with the segmented frequency sweep function. Background technique [0002] A signal generator is a measuring device that can generate certain periodic time function waveforms (sine wave, square wave, triangle wave, sawtooth wave and pulse wave) or arbitrary waveforms, which can be applied to communication, instrumentation and automatic control system testing and other fields. [0003] With the development of electronic technology, the signal generator is required to be able to generate sweeping signals. The existing sweeping functions mainly include continuous sweeping, hopping sweeping and single-segment sweeping. These sweeping methods can only One-time setting corresponds to the output of one-segment frequency sweep signal, which is not applicable to the application where multiple-segment frequency sweep signal can ...
