Abstract

This versatile method for high speed analogic events measurement is intended to work in delayed signal processing, the signal being temporarily stored and then processed at a lower speed and sent to the analyzer system. The principle of this method is to temporarily store the high speed signal using an n-position analogic shift register with start/ stop mode possibility. Thus the very high speed phenomena can be temporarily stored in the shift register, the process is then stopped, and the signal is transferred to the output at a lower speed in accordance with user velocity. The user side comprises a processor provided with an analogic sensor unit. The results are analyzed by the processor program and transformed in numerical values to be printed or put in a diskette file.

High Speed Analogic Measurement

This versatile method for high speed analogic events measurement is intended to work in delayed signal processing, the signal being temporarily stored and then processed at a lower speed and sent to the analyzer system. The principle of this method is to temporarily store the high speed signal using an n-position analogic shift register with start/ stop mode possibility. Thus the very high speed phenomena can be temporarily stored in the shift register, the process is then stopped, and the signal is transferred to the output at a lower speed in accordance with user velocity. The user side comprises a processor provided with an analogic sensor unit. The results are analyzed by the processor program and transformed in numerical values to be printed or put in a diskette file. An immediate visualization of the measurement results, numerical values or analog curve, is made on the graphic display. This method is a not a real-time analysis, but a delayed signal analysis due to the input/output clocking rate difference; nevertheless, the waiting time between the phenomena recording and the result availability is very short depending upon the processor processing time. Thus the action to be taken to modify the system and, by the way, enhance the quality, can be made in a very short time. This method can be used in a noise analyzer to detect the residual pulses after filtering, in a device under test.
