Sin(x)/x
Press Sin(x)/x to enable or disable the dynamic sine interpolation function which
can acquire better restoration of the original waveform.
Note: If the number of channels currently turned on is less than three, Sin(x)/x is
grayed out and disabled.
Sample Rate
The maximum sample rate of DS1000Z-E is 1 GSa/s.
Note: The sample rate is displayed in the status bar at the upper side of the screen
and in the Sa Rate menu and can be changed by adjusting the horizontal time base
through HORIZONTAL SCALE or modifying the "Memory Depth".
The influence on the waveform when the sample rate is too low:
1. Waveform Distortion: when the sample rate is too low, some waveform
details are lost and the waveform displayed is rather different from the actual
signal.
2. Waveform Confusion: when the sample rate is lower than twice the actual
signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt
from the sample data is lower than the actual signal frequency.
