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 MSO1000Z/DS1000Z 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.
