Description
Technical field
The utility model is the signal triggering technology, particularly the multichannel synchronous triggering device.
Background technology
In a lot of test macros, often to trigger many instruments simultaneously as the time test benchmark with a signal source, because all there is the input internal resistance in every instrument, the output impedance of signal source and the input of many instruments are difficult to coupling, just can not realize triggered as normal when indexs such as the power of signal source, amplitude, forward position reach requiring of the external triggering signal of instrument.The multichannel synchronous triggering device arises at the historic moment, and realizes one tunnel input, and multichannel is the function of output synchronously.With the development of technology, output signal develops into light signal from the simple signal of telecommunication, or the state of the signal coexistence of dual mode.When system was output as light signal, present solution was that the output at original synchronous triggering device inserts a plurality of electro-optical conversion circuits, realized that with the mode of conversion of signals the multichannel synchronizable optical triggers.And, can cause the inherent delay of system to increase just because of having introduced extra circuit, self difference of each road device also will influence the synchronism between each road of multichannel output signal.Existing multichannel synchronous triggering device is core with the analog circuit, amplify a plurality of pulses of back formation by input electrical signal being carried out shaping, drive a plurality of electro-optical conversioning devices and remove to export multipath light signal, this circuit structure complexity, the inherent characteristic difference of electro-optical conversioning device also can influence the net synchronization capability of device.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of electro-optical conversioning device that has only is provided, and circuit is simple, and inherent delay is little, stable performance, the multichannel synchronous triggering device that the multipath light signal net synchronization capability of output is good.
Solution of the present utility model is: a kind of multichannel synchronous triggering device, comprise signal source, the signal of telecommunication of signal source is carried out the electro-optical conversion circuit of electric light conversion, be characterized in that the light triggering signal after the electro-optical conversion circuit conversion is input to optical splitter, the multipath light signal of optical splitter beam split output triggers many instruments respectively.
Can in the beam split light path of optical splitter output, image intensifer be set in the solution of the present utility model.Its effect is that light signal is amplified, and improves luminous power, to adapt to the demand of different instruments.
Optical splitter adopts GST-1X2-1310 in the solution of the present utility model.
The utility model has the advantages that: because the light triggering signal after the electro-optical conversion circuit conversion is input to optical splitter, the multipath light signal of optical splitter beam split output triggers many instruments respectively, and corresponding multipath light signal net synchronization capability is good; Adopted optical splitter, only needed an electro-optical conversioning device, saved input electrical signal is carried out shaping amplification and drive circuit, circuit is simplified greatly, and inherent delay is little, stable performance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model embodiment is as shown in Figure 1: among Fig. 1 signal after the input of left side, the protective circuit of voltage regulation of forming through resistance R 1 and voltage stabilizing didoe D1, with the amplitude limitation of input signal in 5V.IC is a NAND gate, an input signal of importing behind the termination amplitude limit, another input is pulled to VCC by resistance R 2, when input signal when low, high level signal of NAND gate IC output is to the base stage of triode T1, triode T1 conducting, loop, light-emitting diode D2 place no current, not luminous; When input signal when being high, low level signal of NAND gate IC output is to the base stage of triode T1, and triode T1 ends, and power supply VCC is luminous through current-limiting resistance R4 rear drive light-emitting diode D2.The light signal that light-emitting diode D2 sends is by optical splitter G1, according to many instrument OUT of power demand demultiplexing synchronizable optical signal triggering, power do not reached trigger to require, the synchronizable optical signal also will carry out luminous power by image intensifer G2 and amplify the back and trigger instrument OUT.
