Oscilloscopes User’s Manual MSO3000HD Series 13. Sampling System  Sampling Rate  Acquistion Mode  Memory Depth  Interpolation Method  Enhanced Resolution (ERES) Sampling is the conversion of the signal from an analog input channel, through an analog-to-digital converter (ADC), into a discrete point.
Page 195 Oscilloscopes User’s Manual MSO3000HD Series rate of MSO3000HD series high-definition oscilloscopes is 2.5 GSa/s. The sampling rate will change with the time base scale and memory depth. The real-time sampling rate is displayed in the A sampling label at the top of the screen, the horizontal time base can be adjusted by using the horizontal Scale or change the “Memory Depth”.
Page 196: Acquisition Mode
Oscilloscopes User’s Manual MSO3000HD Series 13.2. Acquisition Mode The acquisition mode controls how the oscilloscope uses the sampling rate to create a waveform. In the “Sampling” menu, click on the “Acquisition Mode” to select the mode. (1) Normal Sampling The oscilloscope samples the signal and reconstruct the waveform with equal time interval in normal mode.
Page 197: Memory Depth
Oscilloscopes User’s Manual MSO3000HD Series Note: Average and high resolution uses different average methods. The former is “multiple sampling averaged”, the latter is “single sampling averaged”. (5) Enhanced Resolution If the signal-to-noise ratio and the effective resolution of the oscilloscope need improvement, select the enhanced resolution acquisition method, then set the desired number of enhanced resolution bits.
Page 198 Oscilloscopes User’s Manual MSO3000HD Series interpolation methods. Sinc Interpolat Linear Interpolation Interpolation Method Comparison 13.5. Enhanced Resolution (ERES) In Enhanced Resolution mode, the oscilloscope digitally filters the sampling points, reducing broadband random noise on the input signal and improving the signal-to-noise ratio, thereby increasing the effective resolution (ENOB) of the oscilloscope.
