event. The highest real-time sample rate on the analog channel of MSO7000/DS7000
series is 10 GSa/s. The current sample rate is displayed under CH Sa Rate.
Sample Rate
Sampling is the process of converting the analog signal into the digital signal at a
specified time interval and then restoring them in sequence. The sample rate is the
reciprocal of the time interval.
The sample rate of the analog channel is related to the current channel mode. The
maximum real-time sample rate in the single-channel mode of the oscilloscope is 10
GSa/s. The maximum real-time sample rate in the dual-channel mode is 5 GSa/s, and
the maximum real-time sample rate in the 4-channel mode is 2.5 GSa/s.
Note: The sample rate is displayed both in the status bar at the upper part of the
screen and in the CH Sa Rate menu. To indirectly modify the sample rate,
rotate the Horizontal
SCALE knob to adjust the horizontal time base or
modify the memory depth.
The impact of low sample rate on the waveform:
1. Waveform Distortion: when the sample rate is too low, some waveform
details are lost, and the sample waveform displayed is rather different from the
actual waveform of the signal.
Tip
Press RUN/STOP on the front panel to stop sampling, and then the oscilloscope
will maintain its last captured graph. You can still expand or zoom the waveforms
by using the horizontal and vertical control knobs.
Tip
Single-channel mode: only one of the four channels (CH1/CH2/CH3/CH4) is
enabled.
Dual-channel mode: either CH1 or CH2 is enabled; and either CH3 or CH4 is
enabled.
4-channel mode: CH1/CH2 are both enabled or CH3/CH4 are both enabled.
