Study on Signal Conditioning Technology in 2GHz Broadband Digital Oscilloscope
Its the trend of electronic development to test the broadband signal The channels of frond-end broadband signal conditioning constitute the key for the high-speed digital oscilloscope, in other words, the performance of such conditioning channels will determine the signal acquisition capacity of digital oscilloscope.In combination with the specific signal conditioning requirements, the paper describes the design of functional circuit for the high-speed digital oscilloscope,which inchudes broadband impedance transfer circuit, variable gain circuit, high-speed parallel drive circuit and high-speed trigger circuit.The major technologies of broadband signal conditioning is further analyzed.In view of the experience of practical system commissioning, the DC-2GHz broadband signal conditioning test is feasible.The design could be suggested to use in other broadband instruments.
