Description
Technical field
The present invention relates to show a kind of probe, particularly relate to a kind of improved multi-channel signal acquisition probe.
Background technology
Current high-performance multi channel signals is on the market caught probe, and in order to guarantee the quality of collection signal, its each passage all can adopt separate coaxial cable to carry out transmission of electric signals.Some on electrical property independently coaxial cable formed the thicker wider cable of a ribbon or column by different processing technologys.One end of this cable is connected to a connector, be used for surveying instrument on connector interconnect, as measured signal to the interface of surveying instrument.The other end is broken up into separately independently coaxial cable by different structures, has small-signal probe or other collection signal device alone on each root coaxial cable.As the entrance of measured signal.Wherein, the center conductor of coaxial cable is used as the path of signal transmission.The outer shielding conductor of coaxial cable is used to shield to guarantee the quality of signal, and this outer shielding conductor, is usually used to ground connection.
On the other hand, the other end of ribbon cable can be fixed on a built-up circuit platelet by techniques such as welding or crimping.Wherein the central signal conductors of every coaxial signal cable and exterior shield layer conductor are soldered to multiple junctions of switching circuit board.Then card extender separates independently fine rule probe of some structures again.Thin probe is used to contact collection signal with measured point.Each autonomous channel, road of this probe needs one group of front-end circuit, for better collection signal.This part circuit is often soldered on this card extender.But this part circuit need to be more closely better apart from measured source, above scheme between front-end circuit and measured source also interval a bit of cable, this will have a negative impact to the effect of test.
Take Fig. 1 as example: one end of ribbon cable as connector (also referred to as connection-peg) 1, the other end be card extender 2, card extender 2 separates some detecting heads 3.Front-end circuit is generally placed on card extender 2.
Also have another kind of way, some independently coaxial cable be directly connected to front end detecting head from surveying instrument.Front-end circuit is placed on card extender.When the benefit of doing is like this thermometrically, the distance of this partial circuit and measured source is the shortest, and measurement effect is better.Also there is negative effect but do like this to measuring convenience.If measured source is one group of row's pin, while measurement, just have to being connected with measured source first one of detection.And the measured source of often arranging aciculiform formula is the most common.So can have a great impact for connection reliability, and very inconvenient user operation.
Take Fig. 2 as example: many independently coaxial cable one end access respectively connector 4, middle by the adapter piece of particular design, for example sleeve, or by cable processing technology, restrainted as a whole.The other end is separated into independently detecting head 6 again, and front-end circuit is generally placed on detecting head 6.For example, Chinese patent CN200780018189 discloses a kind of multi-channel signal acquisition probe, similar with this structure.
But such maximum problem of popping one's head in now is on the market, during for the measured source of test more complicated, not often very convenient use, lack enough test frontal attachments, and multiple probe easily obscures simultaneously while measuring, cannot distinguish corresponding passage.
