Abstract
The utility model provides an oscilloscope interface switching device. The oscilloscope interface switching device comprises a plurality of first interfaces, an interface switching element of which one end is selectively connected with one of the plurality of first interfaces, and a second interface which is connected with the other end of the interface switching element. By means of the above structure, when an oscilloscope only needs one interface to work, the other interfaces can be prevented from being exposed in the environment.
Description
Technical field
The utility model is a kind of oscillograph interface adaption device.
Background technology
Oscillograph is the characteristic of utilizing electronics oscillatron, and the alternate electrical signal that human eye cannot directly be observed converts image to, is presented on video screen so that the electronic measuring instrument of measuring.It is problem, the requisite important instrument of experiments of measuring result of observing in digital circuit experiment phenomenon, analysis experiment.Oscillograph is made up of oscillatron and power-supply system, synchro system, X-axis deflection system, Y-axis deflection system, delaying sweep system, standard signal source.
Oscillograph is the instrument of the shape for measuring alternating current or pulse current ripple, is made up of discharge-tube amplifier, sweep oscillator, cathode-ray tube (CRT) etc.Except the waveform of observation electric current, can also measure frequency, voltage strength etc.All periodicity physical processes that can become electrical effect can be observed with oscillograph
Based on the difference of channel oscilloscope quantity, oscillograph can be divided into dual channel oscilloscope, triple channel oscillograph and four-way oscillograph etc., the oscillograph of different passages has the interface of the connecting test probe of varying number, below taking four-way oscillograph as example, four-way oscillograph is the signal that can show four tunnels simultaneously, but general triggering only has one, that is to say, you can measure four signals that have correlativity, such as, poor if having time between four signals, you take out existing signal the earliest as triggering judgement, just can carry out four time resolutions between signal etc., but in view of conventionally generally all only using an interface in the process of test, therefore other interface can be exposed in environment owing to not docking probe, in the process using, easily cause because the false touch of conducting medium affects test result.
In view of this, the utility model provides a kind of oscillograph interface adaption device, and it can avoid other interfaces exposed in environment in the time that oscillograph only needs an interfaces.
Summary of the invention
Fundamental purpose of the present utility model is to provide a kind of oscillograph interface adaption device, and it can avoid other interfaces exposed in environment in the time that oscillograph only needs an interfaces.
For reaching above-mentioned purpose, the utility model provides a kind of oscillograph interface adaption device, and it comprises: several first interfaces; One interface switching device, its one end is optionally connected with the wherein interface in described several first interfaces; And second interface, it is connected with the other end of described interface switching device.
Preferably, described interface switching device is a rotation switch piece.
Compared with prior art, oscillograph interface adaption device of the present utility model is by arranging several first interfaces that dock with oscilloprobe interface, second interface docking with probe, and between described several first interfaces and described the second interface, described interface switching device is set, thereby user can make described the second interface optionally be connected with a described wherein first interface by operating described interface switching device, whereby, user only needs a probe to be docked on described the second interface, by regulating described interface switching device, can realize and in the time that oscillograph only needs an interfaces, avoid other interfaces exposed in environment.
[brief description of the drawings]
Fig. 1 is the unassembled view on oscillograph of the utility model oscillograph interface adaption device.
Fig. 2 is that the utility model oscillograph interface adaption device is assembled in the use view on oscillograph.
[embodiment]
Refer to shown in Fig. 1, the utility model provides a kind of oscillograph interface adaption device 1, and it is applicable to an oscillograph 2, and described oscillograph 2 has several probe interfaces 20 that connects probe (not shown), in the present embodiment, and taking 4 probe interfaces 20 as example.As shown in Figure 1, oscillograph interface adaption device 1 of the present utility model has several first interfaces 10, an interface switching device 11 and one second interface 12.
Described several first interfaces 10, the probe interface 20 of its corresponding described oscillograph 2 arranges, for docking one by one with the probe interface 20 of described oscillograph 2.
Described interface switching device 11, its one end optionally with wherein described in one several first interfaces 10 be connected, in the present embodiment, described interface switching device 11 is a rotation switch piece, it also can realize the element of this function for existing other, does not do at this.
Described the second interface 12, it is for connecting a test probe (not shown), and connects the other end of described interface switching device 11.
In the time will using, as shown in Figure 2, the first interface of oscillograph interface adaption device 1 of the present utility model 10 is docked one by one to the probe interface 20 of the above oscillograph 2, then probe is connected to the second interface 12 of oscillograph interface adaption device 1 of the present utility model, the last adjustable described interface switching device 11 of user makes it be connected with wanting the oscilloprobe interface 20 using, whereby, user can use the probe that connects upper oscillograph interface adaption device 1 of the present utility model for test, in the time will using oscillographic probe interface 20 instead, user can regulate described interface switching device 11 again, as can be seen here, can avoid the exposed unnecessary trouble of bringing in the external world of untapped oscillograph interface by oscillograph interface adaption device 1 of the present utility model.
In sum, the various embodiments described above and diagram are only the preferred embodiment of the utility model, but can not with the scope of restriction the utility model enforcement, the equalization of generally being done according to the utility model claim changes and modifies, and all should belong in the scope that the utility model patent contains.
