The Design And Research Of Arbitrary Waveform Generator

The Arbitrary Waveform Generator is one kind of the signal source, it has the characteristics that there are the signal sources, favored by people because of its high performance advantage. The signal source provides the known signals needed for circuit-under-test mainly (various kinds of waveforms), then measure the parameter that is interested in with other instrument. It is obvious the signal source is used and test testing while dealing with in various kinds of experiments, it is not a measuring instrument, but according to the request of user, as encourage source, emulation various kinds of test signal, offer to the circuit-under-test, in order to meet measurement or various kinds of actual needs. Our country has already begun to develop the Arbitrary Waveform Generator at present, make the gratifying achievement. But generally speaking, the generator of Arbitrary Waveform Generator of our country has not formed the real industry yet. So far as present domestic maturity products, it is some PC instruments that insert the card, there are little the independent instrument and module of VXI system, and our country all have greater disparity with the foreign like product in the kind and performance of the Arbitrary Waveform Generator at present, so step up seeming extremely urgent to the reseach of this kind of product.. The main task of this thesis is to develop the core of regarding digital simulation chip AD760 of AD Company as because of DDS technology, Cygnal Company C8051F310 one-chip computer designs a of good performance Arbitrary Waveform Generator as the controller . Thesis design corresponding research to Arbitrary Waveform Generator and hardware of generator that computer control mainly, by CPU, DAC, the counter , timer module is it is it receive to upper strata waveform datum to used for mainly to make up, store, can use alone at the same time, send the necessary waveform data to DAC through CPU. At the time of the...
