Note:
In Y-T mode, the oscilloscope could use arbitrary sample rate (within the
guaranteed range) to capture waveform. The maximum sample rate of Y-T

In this mode, the oscilloscope acquires the maximum and minimum values of the
sample interval signal to get the envelope or the narrow pulse of the signal that
might be lost. Use this mode to avoid signal confusion at the expense of
exaggerating the noise.
In this mode, the oscilloscope can display all the pulses whose pulse widths are at
least as wide as the sample period.
High Resolution
This mode uses a kind of ultra-sample technique to average the neighboring points
of the sample waveform to reduce the ran dom noise on the input signal a nd generat e
much smoother waveforms on the screen. This is generally used when the sample
rate of the digital converter is higher than the save rate of the acquisition memory.

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. DS6000 provides a memory depth up to 140 M points.
The relationship of memory depth, sample rate a nd waveform length fulfills the
following equation:
Press ACQ Mem Depth, use to select the desired memory depth (the default
is auto) and then press the knob to select the option. You can also press Mem Depth continuously to switch the memory depth.
When a single channel (CH1 or CH2, CH3 or CH4) is turned on, the m emory depth
can be set to Auto, 14kPoints, 140kPoints, 1.4 MPoints, 14MPoints or 140MPoints. In
"Auto" mode, t he oscilloscope selects the memory depth aut omati cally ac cor di ng to
the current sample rate.
When two channels are tu rned on (CH1 and CH2, CH3 and CH4), the memory depth
can be set to Auto, 7kPoints, 70kPoints, 700kPoints, 7MPoints and 70MPoints. In
"Auto" mode, the oscilloscope selects the memory depth automatically according to
the current sample rate.
At slower sweep speeds, the sample rate is reduced and a proprietary display
algorithm is used to minimize the likelihood of aliasing.
Press ACQAnti-Aliasing to turn on or off the anti-aliasing function. By default,
anti-aliasing is disabled. The displayed w aveforms will be more suscepti ble to aliasing
when this function is disabled.
For trigger, you set certain trigger condition according to the requirement and when
a waveform in the waveform stream meets this condition, the oscilloscope captures
this waveform as well as the neighbouring part and displays them on the screen.
When the oscilloscope is working, it continuously acquires waveform data even if a
valid trigger does n ot occur. However, only when valid tri gge rs o c cur, can the display
become stable. The trigge r circuit guarantees that each sweep or sample starts when
the input signal meets the user-defined trigger condition, namely each sweep and
sample are synchronous and the waveforms acquired overlap to display stable
waveform.
Trigger setting should be based on the features of the input signal, th us yo u n eed to
have some knowledge of the signal under test to quickly capture the desired
waveform. This oscilloscope provides abundant advanced trigger functions which
help you to focus on the waveform details of interest.
Press MENU (in the tri gger con trol a rea (TRIG GER) on the front panel ) Source to
select the desired trigger source. Signals input from the analog channels CH1-CH4
and the [EXT TRIG] connector as well as the A C Line can all be used as the trigger
source.
MENU
Analog channel input:
Signals input from analog channels CH1-CH4 can all be used as the trigger source.
No matter whether the inp ut from the channel select ed is displaye d, the channel can
work normally.
External trigger input:
The external trigger source can be used to trigger on the fifth channel at the same
time when all the four channels are acquiring data. The trigger signal (e.g. external
clock, signal of the circuit to be tested) will be connected to EXT or EXT/5 trigger
source via the [EXT TRIG] connector. You can set the trigger conditions within the
range of the trigger level from -0.8 V to +0.8 V.
AC Line:
The trigger signals are obtained from the AC power input of the oscilloscope. This
kind of signals can be used to display the relationship between signal (such as
illuminating device) and power (power supply devic e). For example, to stably trigger
the waveform output from the transformer of a transformer substation; it is mainly
used in related measurement of the power industry.
T rigger mo de would influence the mode in which the oscilloscope searches f or trigger
event. The following is t he s chematic diagram of the acquisit ion me mory fr om which
you can see that the position o f the trigger event is d etermined by the refe rence time
point and the delay setting.
Pre-trigger Buffer Post-trigger Buffer
Acquisition memory
Pre-trigger/ Delayed trigger:
Acquire data before/after the trigger event. The trigger position is usually at the
horizontal center of the screen. In full-screen display, you can view seven-grid
pre-trigger and dela yed t rigge r inf or mat ion. You can adjust the horizontal position of
the waveform through HORIZONTAL
information or delayed trigger information, through which to know the signal
information before/after the trigger (e.g. capture the glitch generated by the circuit
and analyze the pre-trigger data to find out the reasons for generating glitch).
Press MODE in the tri gger control area (TRIGGER) on the f ront panel or thr ough the
MENU Sweep menu to se lect the desired trigger mode. The corresponding
status light of the mode currently selected turns on.
No matter whether the trigger condition is met, there is always waveform display. A
horizontal line is displayed when no signal is input.
When this mode is sele cted, t he oscillos cope fills the pre-trigger buffer first and then
search for a trigger while at the same time continues filling data. When the
oscilloscope is searching for trigger, the data f irstly filled into the pre-trigger buffer
will overflow and be pushed out of the FIFO queue. When a trigger is found, the
pre-trigger buffer would contain the data acquired before the trigger. If no trigger is
found, the oscilloscope will trigger forcefully.
This trigger mode is applicable to signals with low repetitive rate and signals with
unknown level. To display DC signals, this trigger mode must be used.
Normal:
Display the waveform when the trigger condition is met or hold the original
waveform and wait for the next trigger when the trigger condition is not met.
When this mode is sele cted, t he oscillos cope fills the pre-trigger buffer first and then
search for a trigger while at the same time continues filling data. When the
oscilloscope is searching for trigger, the data f irstly filled into the pre-trigger buffer
will overflow and be pushed out of the FIFO queue. When a trigger is found, the
oscilloscope will fill the post-trigger buffer and display the acquisition memory.
This trigger mode is applicable t o signal with low repetitive rate and signal that does
not require auto trigger.
Note: In this mode, p re s s FORCE to generate a trigger signal forcefully.
Single:
After this mode is selected, the bac klight of Single turns on, the oscilloscope waits
for a trigger and displays the waveform when the trigger condition is met and then
stops.
Note: In this mode, press FORCE to generate a trigger signal forcefully.
Trigger coupling decides which kind of components will be t ransmitted to the trigger
circuit. Note to distinguish it with "Channel Coupling".
DC: allow the DC and AC components to pass the trigger path.
AC: block all the DC components and attenuate signals lower than 8 Hz.
LF reject: block the DC components and reject the low frequency components
lower than 5 kHz.
HF reject: reject the high frequency components higher than 50 kHz.
Press MENU (in the trigger control area (TRIGGER) on the front panel) Setting Coupling to sel ect the de sired coupling type (the default is DC).
Note: Tri gger coupling is only valid in edge trigger.
