MAINS, and specially protected (internal) MAINS derived circuits. In the latter case,
transient stresses are variable. For that reason, the transient withstand capability of
the equipment is made known to the user.
Measurement category II is for measurements performed on circuits directly
connected to low voltage installations. Examples are measurements on household
appliances, portable tools and similar equipment.
Measurement category III is for measurements performed in building installations.
Examples are measurements on distribution boards, circuit-breakers, wiring
(including cables, bus-bars, junction boxes, switches and socket-outlets) in fixed
installations, equipment for industrial use and some other equipment. For example,
stationary motors with permanent connection to a fixed installation.
Measurement category IV is for measurements performed at the source of a
low-voltage installation. Examples are electricity meters and measurements on
primary overcurrent protection devices and ripple control units.

To Enable the Analog Channel
DS1000Z-E provides 2 analog input channels (CH1 and CH2). As the setting methods
of the vertical systems of the two channels are the same, this chapter takes CH1 as
an example to illustrate the setting method of the vertical system.
Connect a signal to the channel connector of CH1 and then press CH1 in the vertical
control area (VERTICAL) on the front panel to enable CH1. At this point, the channel
setting menu is displayed at the right side of the screen and the channel status label
at the bottom of the screen (as shown in the figure below) is highlighted. The
information displayed in the channel status label is related to the current channel
setting.
After the channel is turned on, modify the parameters such as the vertical scale,
horizontal time base, trigger mode and trigger level according to the input signal for
easy observation and measurement of the waveform.
Channel Coupling
The undesired signals can be filtered out by setting the coupling mode. For example,
the signal under test is a square waveform with DC offset.
When the coupling mode is "DC": the DC and AC components of the signal under
test can both pass the channel.
When the coupling mode is "AC": the DC components of the signal under test
are blocked.
When the coupling mode is "GND": the DC and AC components of the signal
under test are both blocked.
Press CH1 Coupling and use to select the desired coupling mode (the
default is DC). The current coupling mode is displayed in the channel status label at
the bottom of the screen as shown in the figure below. You can also press Coupling
continuously to switch the coupling mode.

Bandwidth Limit
DS1000Z-E supports the bandwidth limit function which can reduce the display noise.
For example, the signal under test is a pulse with high frequency oscillation.
When the bandwidth limit is disabled, the high frequency components of the
signal under test can pass the channel.
When limiting the bandwidth to 20 MHz, the high frequency components of the
signal under test that exceed 20 MHz are attenuated.
Press CH1, then press BW Limit continuously to switch the bandwidth limit state
(the default is OFF). When the bandwidth limit is enabled, the character "B" will be
displayed in the channel status label at the bottom of the screen.
Note: Bandwidth limit can reduce the noise as well as attenuate or eliminate the
high frequency components of the signal.

Vertical Scale
Vertical scale refers to the voltage value per grid in the vertical direction on the
screen and is usually expressed as V/div.
Press CH1 and rotate VERTICAL SCALE to adjust the vertical scale (clockwise
to reduce the scale and counterclockwise to increase). The size of the displayed
waveform will be changed accordingly. The scale information (as shown in the figure
below) in the channel label at the bottom of the screen will change accordingly
during the adjustment. The adjustable range of the vertical scale is related to the
probe ratio currently set. By default, the probe ratio is 10X and the adjustable range
of the vertical scale is from 10 mV/div to 100 V/div.
The vertical scale can be adjusted in "Coarse" or "Fine" mode. Press CH1
Volts/Div to switch the adjustment mode.
Coarse adjustment (take counterclockwise as an example): set the vertical scale
in 1-2-5 step namely 10 mV/div, 20 mV/div, 50 mV/div, 100 mV/div…100 V/div.
Fine adjustment: further adjust the vertical scale within a relatively smaller
range to improve vertical resolution. If the amplitude of the input waveform is a
little bit greater than the full scale under the current scale and the amplitude
would be a little bit lower if the next scale is used, fine adjustment can be used
to improve the amplitude of waveform display to view signal details.
Note: You can also press VERTICAL SCALE to quickly switch between "Coarse"

Delay Calibration of the Analog Channel
When using an oscilloscope for actual measurement, the transmission delay of the
probe cable may bring relatively greater error (zero offset). DS1000Z-E supports user
to set a delay time to calibrate the zero offset of the corresponding channel. Zero
offset is defined as the offset of the crossing point of the waveform and trigger level
line relative to the trigger position, as shown in the figure below.
Figure 2-1 Zero Offset
Press CH1 Delay-Cal and use to set the desired delay time. The range
available is from -100 ns to 100 ns. Pressing down the multifunction knob will
reset the delay time to 0.00 s.
Note: This parameter is related to the instrument model and the current horizontal
time base setting. The larger the horizontal time base is, the larger the setting step
will be. Take DS1202Z-E as an example. The step values under different horizontal
time base are as shown in the table below.

mode to voltage-voltage display mode. The phase deviation between two signals
with the same frequency can be easily measured via Lissajous method. The figure
below shows the measurement schematic diagram of the phase deviation.
Figure 3-2 Measurement Schematic Diagram of Phase Deviation
DS1000Z-E User Guide 3-3
RIGOL Chapter 3 To Set the Horizontal System
According to sin=A/B or C/D (wherein, is the phase deviation angle between
the two channels and the definitions of A, B, C and D are as shown in the figure
above), the phase deviation angle is obtained, that is:
=arcsin (A/B) or arcsin (C/D)
If the principal axis of the ellipse is within quadrant I and III, the phase deviation
angle obtained should be within quadrant I and IV, namely within (0 to π/2) or (3π/2
to 2π). If the principal axis of the ellipse is within quadrant II and IV, the phase
deviation angle obtained should be within quadrant II and III, namely within (π/2 to
π) or (π to 3π/2).
The XY function can be used to measure the phase deviation occurred when the
signal under test passes through a circuit network. Connect the oscilloscope to the
circuit to monitor the input and output signals of the circuit.
Application example: measure the phase deviation of the input signals of two
channels.
Method 1: Use Lissajous method
1. Connect a sine signal to CH1 and then connect a sine signal with the same
frequency and amplitude but a 90° phase deviation to CH2.
2. Press AUTO and then adjust the vertical positions of CH1 and CH2 to 0 V.
3. Set the time base mode to XY, press X-Y and select "CH1-CH2". Rotate
Horizontal SCALE to adjust the sample rate properly to get better
Lissajous figure for better observation and measurement.
4. Rotate VERTICAL SCALE of CH1 and CH2 to make the signals easy to
observe. At this point, the circle as shown in the figure below should be
displayed.
5. Observe the measurement result shown in the figure above. According to the
measurement schematic diagram of the phase deviation (as shown in Figure
3-2), A/B (C/D) = 1. Thus, the phase deviation angle =arcsin1=90°.

Chapter 3 To Set the Horizontal System RIGOL
Slow Sweep
Slow sweep is similar to Roll mode. In YT mode, when the horizontal time base is
set to 200 ms/div or slower, the instrument enters "slow sweep" mode in which the
instrument first acquires the data at the left of the trigger point and then waits for a
trigger event. After the trigger occurs, the instrument continues to finish the
waveform at the right of the trigger point. When slow sweep mode is used to
observe low frequency signal, DC "Channel Coupling" mode is recommended.
Note:
The maximum sample rate of XY mode is 500 MSa/s. Generally, longer sample
waveform can ensure better display effect of Lissajous figure. But due to the
limitation of the memory depth, you have to reduce the waveform sample rate
to acquire longer waveform (refer to the introduction in "Memory Depth").
Therefore, during the measurement, reducing the sample rate properly can
acquire better display effect of Lissajous figure.
When XY mode is enabled, "Delayed Sweep" will be disabled automatically.
Press X-Y to select "CH1-CH2", and the instrument automatically turns on the
two corresponding channels. The X-axis tracks the voltage of the first channel;
the Y-axis tracks the voltage of the second channel.
The following functions are not available in XY mode:
"Delayed Sweep", "Vectors", "Protocol Decoding", "Acquisition Mode",
"Pass/Fail Test", "Waveform Record", and "To Set the Persistence
Time".
Method 2: Use the shortcut measurement function
Please refer to "Phase 12" and "Phase 12" measurement functions of "Delay
and Phase" on page 6-27.
Roll Mode
In this mode, the waveform scrolls from right to left to update the display.
The horizontal position and trigger control of the waveform are not available. The
range of horizontal scale adjustment is from 200 ms to 50.0 s.
Note: When Roll mode is enabled, the waveform "horizontal position", "Delayed

Acquisition Mode
The acquisition mode is used to control how to generate waveform points from
sample points.
Press Acquire Mode on the front panel and use to select the desired
acquisition mode (the default is normal), then press down the knob to select this
mode. You can also press Mode continuously to switch the acquisition mode.
Normal
In this mode, the oscilloscope samples the signal at equal time interval to rebuild the
waveform. For most of the waveforms, the best display effect can be obtained using
this mode.
Peak Detect
In this mode, the oscilloscope acquires the maximum and minimum values of the
signal within the sample interval to get the envelope of the signal or the narrow pulse
of the signal 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 least as
wide as the sample period.
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.
Greater number of averages can lower the noise and increase the vertical resolution;
while at the same time, it will slow the response of the displayed waveform to the
waveform changes.
When "Average" mode is selected, press Averages and use to set the desired
number of averages. The number of averages can be set to 2, 4, 8, 16, 32, 64, 128,
256, 512 or 1024. The default is 2.

High Resolution
This mode uses a kind of ultra-sample technique to average the neighboring points
of the sample waveform to reduce the random noise on the input signal and generate
much smoother waveforms on the screen. This is generally used when the sample
rate of the digital converter is higher than the storage rate of the acquisition memory.
Note: "Average" and "High Res" modes use different averaging methods. The
former uses "Multi-sample Average" and the latter uses "Single Sample Average".

Sample Rate
The maximum sample rate of DS1000Z-E 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.

Memory Depth
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 sample
memory. DS1000Z-E provides up to 24 Mpts standard memory depth.
Figure 4-1 Memory Depth
The relation of memory depth, sample rate and horizontal time base scale fulfills the
equation below:
: Memory depth. The unit is pts.
: Sample rate. The unit is Sa/s.
: Horizontal time base scale. The unit is s/div.
: Number of grids horizontally. The unit is div. For DS1000Z-E, this value is 12.
Therefore, under the same horizontal time base scale, higher memory depth can
ensure higher sample rate.
Press Acquire Mem Depth, use to switch to the desired memory depth (the
default is auto) and then press down the knob to select the option. You can also
press Mem Depth continuously to switch the memory depth.
― When a single channel is enabled, the memory depths available include

Chapter 5 To Trigger the Oscilloscope
As 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. For digital oscilloscope, it samples waveform continuously no matter whether
it is stably triggered, but only stable trigger can ensure stable display. The trigger
module ensures that every time base sweep or acquisition starts from the
user-defined trigger condition, namely every sweep is synchronous to the acquisition
and the waveforms acquired overlap to display stable waveform.
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
help you to focus on the desired waveform details.

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 and post-trigger buffer.
Figure 5-1 Schematic Diagram of the 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 data sampled will still be transmitted to the pre-trigger buffer (the
new data will continuously overwrite the previous date). 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).
Press MODE in the trigger control area (TRIGGER) on the front panel or press
MENU Sweep to select the desired trigger mode. The corresponding status light
