Tektronix's TDS series digital real-time oscilloscope has already been widely used everywhere, and its supporting expansion module TDS2CM and TDS2MM module has the function of two-way communication with external equipment, which can be directly connected with the printer and microcomputer, making the storage and printing of waveform very convenient. Among them, the TDS220 digital oscilloscope has a bandwidth of 100MHZ, which can achieve a sampling rate of 1GS/s with a scanning mode of 10 times. When the supporting TDS2CM module USES RS232 cable to connect with the computer through serial port communication, the corresponding software (such as Matlab, etc.) can directly read and process the data and waveform of the oscilloscope.
Therefore can be used in A digital oscilloscope and communication between the PC and in digital signal processing, digital oscilloscope is equivalent to A high speed signal acquisition unit at this time, he put the data into the computer, with Matlab, can realize the high frequency signal acquisition and processing, and compared with the general hardware processor without A/D and D/A conversion process, is the processing precision and velocity have obvious increase, and the price on the oscilloscope kit module TDSCM2 module also cheaper than the corresponding function of hardware processor.
