摘要
数字示波器的某些参数的测试结果在计量校准和实际应用中,采用不同的采用率、采样方式、拟合方式所得到的结果是不同的,这种差异在我们的计量校准和实际应用中是不容忽视的,必须加以考虑。本文就在用数字示波器进行计量校准和实际应用中进行信号测试时,选用不同的带宽、采用率、采样方式、拟合方式及打开通道数目的不同,对校准和测试结果的影响。
In calibrated and actual application , some parameters of the digital oscilloscope test result is distinct to adopt the difference sampling rate , sampling mode, interpolation mode , and in calibrated and actual application this kind of divergence is not noted tolerate to overlook , and have to consider. The paper is written when testing to signal in digital oscilloscope measurement and calibration and the actual application, Choose the difference bandwidth , Sampling rate , Sampling mode , The interpolation mode and opening different number of channels , To the calibrate and test the result effect.
