Abstract
The utility model provides a technical scheme of a general reception excitation module tester. The technical scheme is the general reception excitation module tester characterized by comprising a PC (Personal Computer) machine, a digital signal processor, high-speed LVDS (Low Voltage Differential Signaling) signal transformation modules, and a frequency spectrograph; wherein the PC machine is connected with the digital signal processor; the digital signal processor is connected with the high-speed LVDS signal transformation modules; the high-speed LVDS signal transformation modules are connected with a general reception excitation module; and the frequency spectrograph is connected with the general reception excitation module. The general reception excitation module tester of the utility model can perform digital intermediate frequency output amplitude detection for the general reception excitation module, during a debugging initial period of the module, the general reception excitation module tester can determine whether a digital intermediate frequency signal of the general reception excitation module meets index requirements, thereby greatly reducing debug time, and simultaneously avoiding resource waste caused by that the digital intermediate frequency signal can not be detected.
Description
Technical field
The utility model relates to a kind of module detecting device, especially a kind of general reception stimulating module tester.
Background technology
In the prior art, known technology is that general reception stimulating module radio frequency input frequency is many, and in the total temperature scope, output accuracy, demand on signal quality to the digital medium-frequency signal after down-conversion during small-signal are very high; Require simultaneously to produce continuously or the digital signal of modulation, be used for excitation and produce the required pumping signal of power amplifier, require pumping signal to satisfy system index in full range point, total temperature scope.the digital intermediate frequency detection of general reception stimulating module is related to last digital intermediate frequency output and whether satisfies index request, at the debugging initial stage, owing to there is no relevant testing hardware and software, and RF spot is more, can't the digital medium-frequency signal of general reception stimulating module be detected, often only have by outfield complete machine joint-trial and could find whether digital medium-frequency signal satisfies index request, if find the discontented toe mark requirement of the digital medium-frequency signal of module, again module is reprocessed, a large amount of time and manpower have been wasted, and can not determine whether module can be working properly after reprocessing, inefficiency.And the pumping signal of general reception stimulating module needs the outer test that encourages passage for dissimilar intermediate-freuqncy signal, and when having caused modular debugging and experiment, efficient is low, and this is the existing weak point of prior art.
The utility model content
The purpose of this utility model, be exactly for the existing deficiency of prior art, and provide a kind of technical scheme of general reception stimulating module tester, this scheme can be carried out the detection of digital intermediate frequency output amplitude to general reception stimulating module, at the modular debugging initial stage, whether the digital medium-frequency signal that just can determine general receiver module satisfies index request, greatly reduces debug time, also can avoid because detecting the wasting of resources that causes to digital medium-frequency signal simultaneously.
This programme is achieved by the following technical measures: a kind of general reception stimulating module tester includes PC, digital signal processor, high speed LVDS signal conversion module and frequency spectrograph; PC is connected with digital signal processor; Digital signal processor is connected with high speed LVDS signal conversion module; High speed LVDS signal conversion module is connected with general reception stimulating module; Frequency spectrograph is connected with general reception stimulating module.
Preferred as this programme: this tester also includes radio-frequency signal source and local vibration source; Radio-frequency signal source is connected with local vibration source with general reception stimulating module and is connected.
The beneficial effect of this programme can be learnt according to the narration to such scheme, signal is processed and reduction because the parallel digital signal that collects according to digital signal processor in this scheme carries out, whether qualified with this quality that judges digital medium-frequency signal, digital signal processor produces continuously or the digital signal of modulation simultaneously, be sent to general reception stimulating module, produce the needed pumping signal of power amplifier, by spectrum analyzer, judge whether the pumping signal index is qualified.
This shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.

Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing, a kind of general reception stimulating module tester of this programme includes PC, digital signal processor, high speed LVDS signal conversion module and frequency spectrograph; PC is connected with digital signal processor; Digital signal processor is connected with high speed LVDS signal conversion module; High speed LVDS signal conversion module is connected with general reception stimulating module; Frequency spectrograph is connected with general reception stimulating module; This tester also includes radio-frequency signal source and local vibration source; Radio-frequency signal source is connected with local vibration source with general reception stimulating module and is connected.
During work, by digital signal processor, LVDS digital signal conversion device is configured, allow LVDS digital signal conversion device that high speed LVDS serial digital signal is locked, and the parallel digital signal of output, then by parallel data is gathered, again the data that collect are carried out data and process, by software, digital signal is reduced at last, judge then whether digital signal quality is normal.Simultaneously, digital signal processor can also produce continuously or the digital signal of modulation, be converted at a high speed LVDS serial signal this digital signal being sent to LVDS digital signal conversion device, this signal is sent to general reception stimulating module, in inside modules, producing analog intermediate frequency according to this signal, finally obtain encouraging radiofrequency signal.Can detect the excitation radiofrequency signal by frequency spectrograph and whether satisfy index request.
From measured result, the digital medium-frequency signal of the general reception stimulating module after general reception stimulating module testing scheme detects satisfies index request fully, when the complete machine joint-trial of outfield, can not occur that factor word intermediate-freuqncy signal is off quality causes complete machine work undesired, simultaneously, rf excitation signal with satisfy machine requirement, simplified like this detection means, greatly improved efficient.
