Description
Technical field
The present invention relates to thermometrically field, particularly a kind of mixing oscillograph with Multifunctional knob.
Background technology
Mixing oscillograph, be called for short MSO(Mixed-signal oscilloscopes), be a kind of combination-type corrugated surveying instrument of one combined by the part measurement function of digital oscilloscope and logic analyser, it has the function such as wave form analysis, triggering, decoding, measurement of simulating signal and digital signal simultaneously.
With common digital oscilloscope unlike, mixing oscillograph has the digital channel for logic analysis, and by the probe that logic analysis is special, outside measured signal is input in digital channel, then Measurement and analysis is carried out to measured signal, mixing oscillograph conventional at present has 16 digital channels, when after logic analysis function on, the waveform measuring 16 passages obtained can show on the display screen by mixing oscillograph in a certain order.
In actual applications, user can often according to the demand measured, select the measurement operation that the waveform of digital channel or the passage group of specifying carries out being correlated with, or in order to compare the waveform of two different passages or passage group, and the waveform of this passage or passage group is adjusted to suitable display position (positions of other passages).Therefore, often carry out the selection (setting of current operation waveform) of passage or passage group in order to meet user's needs and the waveform of selected passage or passage group moved the demand of (setting of display position), more existing producers have devised multiple solution, and that wherein commonly uses has following two schemes:
The first adopts multiplexing knob in conjunction with the mode of menu, and which provides one or two Multifunctional knobs on oscillographic panel, realized by operation knob and the mode arranging menu combination.Concrete operation step is: 1) switching menu item is to " current channel " setting option, rotates knob, and arranging the passage that knob chooses is current channel; 3) switching menu item is to " display position " setting option, rotates knob, makes the waveform of current channel move to the display position of knob selection.
The second is the mode adopting Double-knob, which is on oscillographic panel, provide two special knob A and B, be used for respectively arranging " current channel " and " display position " and function, concrete operation step is: 1) rotation knob A, and arranging the passage that knob A chooses is current channel; 2) rotate knob B, make the waveform of current channel move to the display position of knob selection.
, although the setting that can both realize " current operation waveform " and " display position ", all there is certain shortcoming separately in above-mentioned implementation method.For first kind of way, just setting can be completed because needs knob-operated and menu operation combine, therefore operation has certain complicacy, and user is in daily measurement, often repeated setting will be carried out, adopt this mode of operation also greatly to waste the running time, make user can not be absorbed in the change observing waveform, Consumer's Experience can not be fine; For the second way, although eliminate the loaded down with trivial details of menu operation, but adopt two special knobs only in order to realize this two functions, waste hardware resource greatly, and for having the oscillographic panel of multiple button and knob, vacateing position again for placing these two knobs is also be difficult to realize, and therefore the second way not only increases cost, also add the complicacy of structural design.
In sum, lack a kind of operational requirements that both can meet user and above-mentioned functions is arranged in prior art, can cost be saved again, be easy to the mixing oscillograph realized.
