Note:
The "Average" and "High Res" modes use different averaging methods. The
⚫
former uses "Multi-sample Average" and the latter uses "Single-sample
Average".
In "High Res" mode, the signal bandwidth does not exceed 1/32 of the sampling

rate.
In "High Res" mode, the highest waveform refresh rate mode is not supported.

Sampling Mode

This oscilloscope only supports the real-time sampling mode. In this mode, the
oscilloscope produce the waveform display from samples collected during one trigger
event. The highest real-time sample rate on the analog channel of MSO5000-E series
is 4 GSa/s. The current sample rate is displayed under CH SampleRate, and you
can press More → CH SampleRate to view it.
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.

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 4
GSa/s. The maximum real-time sample rate in the all-channel mode is 2 GSa/s.
Tip
Single-channel mode: only one of the channels (CH1 or CH2) is enabled.
All-channel mode: CH1 and CH2 are both enabled.
Note that the currently enabled channel should be used as the trigger source at
this time.
Note: The sample rate is displayed both in the status bar at the upper part of the
screen and in the CH SampleRate menu. To indirectly modify the sample
rate, rotate the Horizontal
