In practice, an oscilloscope’s sample rate should be four or more times its bandwidth: 𝑓

= 4𝑥𝑓

. Doing so causes less
aliasing, and aliased frequency components have a great amount of attenuation.
5.5 Memory Depth
Memory Depth refers to the number of waveform points that the oscilloscope can store in a single trigger sample. It
reects the storage ability of the sample memory.
To set the Memory Depth:
1. Press the Acquire key.
2. Use the softkeys to select Mem Depth (Page 1/2).
3. Turn the Universal Knob to navigate the available option.
4. Push the Universal Knob to set the selected option.
The actual memory depth is displayed in the information area at the upper right corner of the screen.
