UTD2000M User Manual Definition FFT Resolution: it is defined as the quotient of a division between sampling rate and operating points. In case of a fixed operating points, the lower the sampling rate, the better the FFT resolution. Nyquist frequency: For a waveform with the maximum frequency of f, the original waveform can only be built with the use of a sampling rate that is at least 2f. This is also referred to as Nyquist Code. The “f” here is Nyquist frequency, while the “2f” is Nyquist sampling rate.

UTD2000M User Manual Fig. 2‐30 Waveform with Fast Sampling on Notes: To see more details of a waveform, please use “deep memory”. To capture some abnormal signal, please use “fast sampling mode”. For single channel, fast sampling is effective only for a sampling rate between 1ms/div and 100ns/div, while for dual channel, fast sampling is effective only for a sampling rate between 1ms/div and 200ns/div. Definitions Real‐time Sampling: one time sampling of all data needed. The highest real time sampling rate of unit is 1GS/s. Normal Mode: “Normal Sampling Mode” can be used in any time base for fastest sampling. Normal Mode is the default model. Peak Detection Mode: Under this acquiring mode, oscilloscope picks up both the maximum and minimal values within each sampling interval of an input signal and then use these values for waveform displaying. In this way, it allows an oscilloscope to acquire and display narrow pulse. Otherwise, these narrow pulses would have been ...

UTD2000M User Manual Fig. 3‐4 Signal Noise has been Rejected Notes: The use of average sampling makes waveform display and update slower, as well as having no persistence effect, which is a normal phenomenon. High Resolution Reduces Random Noise Average mode has certain defects: the use of average sampling makes waveform display and update slower, as well as having no persistence effect, which is inconvenient for operation under certain circumstance. However, high resolution well overcomes this issue.
