Slow Sweep Mode
In “Y-T” time base mode, when the horizontal time base is greater than or equal to
200 ms/div, the instrument enters “Slow Sweep” mode. In “Slow Sweep” mode, the
oscilloscope first samples the data at the left of the trigger point; then, it waits for
trigger and finishes the waveform at the right of the trigger point. When the slow
sweep mode is used to observe low-frequency signal, it is recommended that the
“channel coupling” is set to “DC” (refer to “To Specify the Channel Coupling”).
Note: Please pay attention to distinguish the slow seep mode from “Roll Mode”.
X-Y Mode
In this mode, the X axis and Y axis both represents voltage. The oscilloscope
automatically turns on all the four channels (CH1 to CH4) a nd the screen is divided
into two areas (XY1 and XY2). In XY1 area (at the left of the screen), the X axis and
Y axis track the voltages of CH1 and CH2 respectively ; in XY2 area (at the right of the

This oscilloscope only supports real-time sampling. In this mode, the oscilloscope
samples and displays waveforms within a trigger event.
Tip
When the sample is stopped, the oscilloscope will hold the last display. At this
the waveform.
Sample Rate
Sample refers to the process that the oscilloscope converts analog signals to digital
signals at a certain time interval and stores the data in order. The sample rate is the
reciprocal of the time interval.
The real-time sample rate of DS4000E is up t o 2 GSa/s for each channel. The current
sample rate is displayed in the status bar at the upper side of the screen and in the
Sa Rate menu (press Acquire Sa Rate). You can change the sample rat e
indirectly by modifying the horizontal time base (refer to “To Adjust the
Horizontal Time Base”) or memory depth (re fer to “To Set the Memory
Depth”).
The influence on the waveform when the sample rate is too low:
1. Waveform Distortion: when the s ample rate is too low, some waveform
details are lost and the waveform displayed is rather different from the actual
signal.
4-2 DS4000E User’s Guide
Page 83
Chapter 4 Sample System Setting RIGOL
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.
3. Waveform Leakage: when the sample rate is too low, the waveform rebuilt
from the sample data does not reflect the actual signal completely.

Normal
In this mode, the oscilloscope sam ples the signal at equal time inte rval to re build the
waveform. For most of the waveforms, the best display effect can be obtained using
this mode.
Average
In this mode, the oscilloscope averages the waveforms from multiple samples to
reduce the random noise of the input signal and improve the vertical resolution.
When “Average” mode is s elected, press Averages and turn the multi-function kno b

Peak Detect
In this mode, the oscilloscope acquires the maximum and minimum values of the
signal within the sample in terval to get the envel ope of the signal or the narrow pulse
that might be lost. In this mode, signal confusion can be prevented but the noise
displayed would be larger.
In this mode, the oscilloscope can display all the pulses with pulse widths at le ast as
wide as the sample period.
High Resolution
This mode uses an over-sample technique to average the neighboring points of the
sample waveform. This reduces the random noise on the input signal, generates a
much smoother wavef orm on the s creen an d improv es the v ertical resolution . This is
generally used when the sample rate of the digital converter is greater than the
storage rate of the acquisition memory.
Note: The “Average” and “High Res” modes use different averaging metho ds. The
former uses “Multi-sample Average” and the latter uses “Single-sample Average”.

Memory Depth
To Set the Memory Depth
The memory depth refers to the number of waveform points that the oscilloscope
can store in a single trigger sample and it reflects the storage ability of the
acquisition memory. DS4000E provides up to 14 Mpts memory d epth for each
channel.
The relation of the memory depth, sample rate and waveform length fulfills the
equation below:
Memory Depth = Sample Rate × Waveform Length
Wherein, Waveform Length = Horizontal Time Base × number of grids horizontally
on the screen. F or DS4000E, the number of grids h orizontally on the screen is alwa ys
14. Therefore, with the same h orizontal t ime base, h igher memo ry depth can e nsure
higher sample rate.
Press Acquire Mem Depth, turn the multi-function knob to select the
desired mem ory depth (t he def ault is auto ); then, press the knob. You can also press
Mem Depth continuously to switch the current memory depth.
The memory depth can be set to Auto, 7 kPoints, 70 kPoints, 700 kPoints and 7
MPoints.
In “Auto” mode, the oscilloscope selects the memory depth automatically
according to the current sample rate. As the sample rate might change when
adjusting the horizontal time base, the memory depth might also change
accordingly.

To ge nera te a t rigger, you set a trigger condition accordin g to the requi rement; when
a waveform in the waveform stream meets this condition, the oscilloscope captures
this waveform as well as the neighbouring part immediately and then displays the

guarantee stable waveform display. The trigger circuit guarantees that each time
sweep and sample start w hen the input s ignal meets the trigger condition defined by
users; namely each sweep and sa mple are synchronous and the waveforms acquired
overlap to display a stable waveform. The trigger setting should be based on the
features of the input signal; thus you need to have some knowledge of the signal
under test to quickly capture the desired waveform. This oscilloscope provides
abundant advanced trigger functions which can h elp you to focus on t he wavefo rm

Trigger and the Pre-trigger/Post-t rigger Buffer
The following is the schematic diagram of the acquisition memory. To easily
understand the trigger event, the acquisition memory is divided into the pre-trigger
buffer an d pos t-trigger buffer.
Trigger Event
Pre-trigger Buffer Post-trigger Buffer
Acquisition Memory
After the system runs, the oscilloscope operates by first filling the pre-trigger buffer.
It starts searching for a trigger after the pre-trigger buffer is filled. While searching
for the trigger, the oscilloscope overflows the pre-trigge r buffer and t he first data put
into the buffer is first pushed out (FIFO). When a trigger is found, the pre-trigger
buffer contains the data acquired just before the trigger. Then, the oscilloscope will
fill the post-trigger buffer and display the data in the acquisition memory. If the
acquisition is activated via RUN/STOP, the oscilloscope will repeat this process; if
the acquisition is activated via SINGLE, the oscilloscope will stop after finishing a
single acquisition (you can pan and zoom the waveform currently displayed).

Trigger Holdoff
The trigger holdoff can be used to set the period of time that the oscilloscope waits
(namely the holdoff time) before re-arming the trigger circuitry after a trigger. The
oscilloscope will not trigger until the holdoff time e xpires. Trigger holdoff can be used
to stably trigger complex repeat waveforms (there are multiple edges (or other
events) within a single repeating period of the waveform, such as pulse series).
For example, to stably trigger the repeat pulse series as shown in the figure below,
the holdoff time should be set to a value greater than t1 and lower than t2.

Pulse Trigger
In pulse trigger, the oscilloscope triggers on the positive or negative pulse with a
specif ied width.
For this oscilloscope, the positive pulse width is defined as the time difference
between the two crossing points of the trigger level and positive pulse and the
negative pulse width is defined as the time difference between the two crossing
points of the trigger level and negative pulse, as shown in the figure below.

, , or , press
Setting and turn the multi-function knob o r the inner knob o f t h e
navigation knob to adjust the pulse width at a relatively smaller st ep or turn
the outer knob of the navigation knob to adjust the pulse width at a
relatively larger step. The range available is from 4 ns to 4 s.
Note: The larger the rotation a mplitude of the o uter knob of the na vigation
knob is, the faster the variation of the value will be. When you need to
adjust the pulse width within a relatively l arger range, this functi on can hel p
you quickly finish the setting.
When the pulse width condition is set to or , press Upper
Limit and Lower Limit respectively and use the multi-function knob
or the navigation knob to adjust the upper limit and lower limit of pulse
width. The range of the upper limit is from 12 ns to 4 s. The range of the
lower limit is from 4 ns to 3.99 s.
Note:
― The lower limit of the pulse width must be lower than the upper limit.
― You can use the outer knob of the navigation knob to quickly adjust the
upper limit and lower limit of pulse width within a relatively larger
range.
