Measurement Category
Measurement Category
MSO7000/DS7000 series digital oscilloscopes can make measurements in Measurement Category I.
Measurement Category Definitions
Measurement category I is for measurements performed on circuits not directly connected to MAINS. Examples are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS derived circuits. In the latter case, transient stresses are variable. Thus, you must know the transient withstand capability of the equipment.
Measurement category II is for measurements performed on circuits directly connected to low voltage installation. Examples are measurements on household appliances, portable tools and similar equipment.
Measurement category III is for measurements performed in the building installation. Examples are measurements on distribution boards, circuit-breakers, wiring (including cables, bus-bars, junction boxes, switches and socket-outlets) in the fixed installation, and 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.
Ventilation Requirement
This oscilloscope uses a fan to force cooling. Please make sure that the air intake and exhaust areas are free from obstructions and have free air. When using the oscilloscope in a bench-top or rack setting, provide at least 10 cm clearance beside, above and behind the instrument for adequate ventilation.

Vertical Scale
Value Input Field Decrease Increase
To Adjust the Vertical Scale
Vertical scale indicates the voltage value per grid in the vertical axis of the screen. It is often expressed in V/div. While you adjust the vertical scale, the display amplitude of the waveform would enlarge or reduce. The scale information of the channel status label (e.g. as shown in the following figure) at the lower section of the screen would change accordingly.
The adjustable range of the vertical scale is related to the currently set probe ratio and input impedance. By default, the probe ratio is 1X and the input impedance is 1
MΩ. In this case, the adjustable range of the vertical scale is from 1 mV/div to 10
V/div.
When CH1 is turned on, you can adjust the vertical scale with the following three methods: Rotate Vertical SCALE that corresponds to CH1 to adjust the vertical scale
(clockwise to reduce the scale and counterclockwise to increase).
Enable the touch screen function and adjust the vertical scale with the pinch &
stretch gesture on the touch screen. For details, refer to the "Pinch & Stretch" section.
Enable the touch screen function, and tap the channel status label at the bottom
of the screen. The following window is displayed. Tap the icon at the right side of the Scale input field to increase or decrease the scale. You can also tap the Scale input field to input a specific value with the displayed numeric keypad.
In the vertical control area (Vertical) on the front panel, press Vertical SCALE to adjust the vertical scale in "Coarse" (by default) or "Fine" mode. You can also press
1  MoreFine to enable or disable fine adjustment. Fine adjustment: Rotate Vertical SCALE to 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.

Vertical Expansion
When changing the vertical scale of the analog channel by rotating the Vertical SCALE knob, you can select to expand or compress the waveform around the
"Center" or "GND" (Ground). By default, "GND" is selected under Expand.
Press 1 More, then press Expand continuously to select "Center" or "GND". Center: when the vertical scale is changed, the waveform will be expanded or
compressed around the screen center.
GND: when the vertical scale is changed, the waveform will be expanded or
compressed around the signal ground level position.
To Adjust the Vertical Offset
Vertical offset indicates the offset of the signal ground level position of the waveform from the screen center in the vertical direction. Its unit is consistent with the currently selected amplitude unit (refer to "Amplitude Unit"). When adjusting the vertical offset, the waveforms of the corresponding channel moves up and down. The vertical offset information (as shown in the following figure) in the channel status label at the bottom of the screen will change accordingly.
The adjustable range of the vertical offset is related to the current input impedance, probe ratio, and vertical scale.
When CH1 is turned on, you can adjust the vertical offset with the following four methods: Rotate Vertical OFFSET that corresponds to CH1 to adjust the vertical
offset within the adjustable range. Rotate this knob clockwise to increase the vertical offset, and rotate it counterclockwise to reduce the vertical offset. Pressing down the knob can quickly reset the vertical offset (set the vertical offset to 0).
Menu setting: Press 1 More Offset, and then the numeric keypad is
displayed. Input the offset value with the numeric keypad.
Enable the touch screen, and then adjust the vertical offset with the drag
gesture. For details, refer to the "Drag" section.
Enable the touch screen function, and tap the channel status label at the bottom

right side of the Scale input field to increase or decrease the offset. You can also tap the Scale input field to input a specific value with the displayed numeric keypad.
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.
Press 1 to open the setting menu of CH1. Then, press Coupling continuously or rotate the multifunction knob to select the desired coupling mode (by default, it
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 enable the touch screen, and then touch the CH1 setting menu to select the desired coupling mode.
DC AC
Note:
When the input impedance is set to "50 Ω", the channel coupling is set to DC
coupling by force, and the Coupling menu is grayed out and cannot be modified.
When the coupling mode is "AC", the input impedance is set to 1 MΩ by force,
and the Impedance menu is grayed out and cannot be modified.
Bandwidth Limit
MSO/DS7000 series supports the bandwidth limit function. Setting the bandwidth limit can reduce the noises in the displayed waveforms. For example, the signal under test is a pulse with high frequency oscillation.

Timebase Mode
MSO7000/DS7000 series supports three available time base modes: YT mode, XY mode, and ROLL mode. By default, the time base mode is YT.
Press Acquire Timebase Mode on the front panel, and then rotate the multifunction knob to select the desired time base mode. Then, press down the
knob to select the mode. You can also press Timebase Mode continuously to select the mode or enable the touch screen to tap the desired mode and select it.
YT Mode
In this mode, the Y axis represents voltage, and the X axis represents time.
Note: Only when this mode is enabled, can delayed sweep be turned on. In this
mode, when the horizontal time base is equal to or greater than 200 ms/div, the instrument enters slow sweep mode. For details, refer to descriptions in "ROLL Mode".
XY Mode
In this mode, both the X axis and the Y axis represent the voltage. The mode changes the display from voltage-time display mode to voltage-voltage display. You can use the Lissajous method to measure the phase deviation of the two input signals whose frequencies are the same. The following figure shows the measurement schematic diagram of phase deviation.

According to sin=A/B or C/D, is the phase deviation angle between the two channels. The definitions of A, B, C, and D are shown in the above figure. 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/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: measures the phase deviation between the input signals of two channels.
Use Lissajous method
1. Connect one sine signal to CH1, and then connect another sine signal (with the same frequency and amplitude as the previous one but a 90° phase deviation from the previous one) to CH2.
2. Press AUTO, after you select "XY" mode, rotate the Horizontal SCALE to adjust the sample rate properly to obtain a better view of Lissajous graph for observation and measurement.
3. Rotate the Vertical SCALE knob that corresponds to CH1 and CH2 respectively to make the signals easy to observe. Then, a circle, as shown in the figure below, should be displayed.
4. Observe the measurement result shown in the figure above. According to the measurement schematic diagram of the phase deviation (as shown in Figure 4-1), A/B(C/D)=1. Thus, the phase deviation angle of the two channel input signals is =arcsin1=90°.

RIGOL Chapter 4 To Set the Sample System
Slow Sweep
It is similar to the ROLL mode. In YT mode, when the horizontal time base is set to 200 ms/div or smaller, the instrument enters the "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 observing the low-frequency signal in the slow sweep mode, it is recommended that you set "Channel
Coupling" to "DC".
Note:
The maximum sample rate in XY mode is 2.5 GSa/s. In this mode, CH1 and CH2
are forced to be enabled; CH3 and CH4 are forced to be disabled. Generally, a 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 a longer waveform (refer to the introduction in "Memory Depth"). Therefore, during the measurement, reducing the sample rate properly can achieve better display effect of Lissajous figure.
The following functions are disabled in XY mode:
"Delayed Sweep", "Vector display", "Scale", "Protocol Decoding", "Acquisition Mode", "Pass/Fail Test", "Waveform Recording & Playing", "Digital Channel", and "To Set the Persistence Time".
ROLL Mode
In this mode, the waveform scrolls from right to left to update the display. The available range of the horizontal scale is from 200 ms to 1 ks. Press More Auto ROLL to select "ON". The system automatically enters the ROLL mode, and there is no slow sweep.
Note:
If the current delayed sweep is enabled, then when you enable the ROLL mode,
the delayed sweep is disabled automatically. When you re-enable the "YT" mode, the delayed sweep will be re-enabled.
The following functions cannot be set in ROLL mode:
"To Adjust the Horizontal Position" (available when the oscilloscope is in "Stop" operating status), "Delayed Sweep", "To Trigger the Oscilloscope",
"Protocol Decoding", "Pass/Fail Test", "Waveform Recording & Playing", and "To Set the Persistence Time".

Acquisition Mode
The acquisition mode is used to control how to generate waveform points from the sample points.
MSO7000/DS7000 supports the following three acquisition modes: Normal, Average, and Peak. By default, the acquisition mode is Normal.
Press Acquire Acquisition on the front panel, and then rotate the multifunction knob to select the desired acquisition mode. Then, press down the knob to
select the mode. You can also press Acquisition continuously to select the mode or enable the touch screen to tap the desired mode and select it.
Normal
In this mode, the oscilloscope samples the signal at a specified fixed time interval to rebuild the waveform. For most of the waveforms, using this mode can produce the optimal display effects.
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 you select "Average" mode, press Averages and rotate the multifunction knob or use the numeric keypad to set the desired number of averages. You can also use the pop-up numeric keypad to input the average count. When the average count value is in power-of-2 increments, a prompt message "Trim average count" is displayed. At this time, a value that is smaller than the one you input and the closest to power-of-2 increments will be input automatically. For example, if you input 9 with the numeric keypad, the average count will be input 8 automatically.
The number of averages can be set to 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, or 65536. By default, it is 2.

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.
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.
MSO7000/DS7000 User's Guide 4-7
www.GlobalTestSupply.com
RIGOL Chapter 4 To Set the Sample System
Pulse disappeared
2. Waveform Aliasing: when the sample rate is twice lower than the actual
signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt from the sample data is smaller 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 all the actual signal information.
LA Sample Rate
LA sampling is the process of sampling on the compared digital signals at a certain time interval. LA sample rate is the reciprocal of the time interval. For example, if the LA sample rate is 500 MSa/s, it indicates that the oscilloscope will make data acquisition on the digital signals at an interval of 2 ns. The maximum LA sample rate of the oscilloscope is 1.25 GSa/s, and its display value is related to the sample rate of the current analog channel.
Note:
1. The digital signals here mentioned refers to the signal obtained from the comparison between the input signal and the user-defined threshold level. The rule of the comparison is that when the amplitude of the input signal is greater than the threshold level, it is judged to be the logic high level; when the amplitude of the input signal is smaller than the threshold level, it is judged to be the logic low level.

Memory Depth
Memory depth refers to the number of points of the oscilloscope that can store in one trigger acquisition. It reflects the storage capability of the acquisition storage. This oscilloscope is equipped with a standard memory depth of up to 500 Mpts.
Figure 4-4 Memory Depth
The following equation shows the relations among memory depth, sample rate, and horizontal time base scale:
——indicates the memory depth. The unit is pts.
——indicates the sample rate. The unit is Sa/s.
——indicates the horizontal time base scale. The unit is s/div.
——indicates the number of grids in the horizontal direction. The unit is div.
Therefore, under the same horizontal time base scale, a higher memory depth can ensure a higher sample rate.
Press Acquire Mem Depth, then rotate the multifunction knob to switch to the desired memory depth, and then press down the knob to select the option. You can also press the Mem Depth key continuously or enable the touch screen to select the memory depth. By default, the memory depth is Auto.

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 neighboring part, and displays them on the screen. For the digital oscilloscope, it samples waveform continuously no matter whether it is stably triggered, but only stable trigger can be stably displayed. The trigger module ensures that every time base sweep or acquisition starts from the user-defined trigger condition, namely every sweep is synchronous with the acquisition and the waveforms acquired is overlapped so as to display the stable waveforms.
Trigger settings should be based on the features of the input signal. To quickly capture the desired waveform, you need to understand the signal under test. This oscilloscope provides abundant trigger types that help you focus on the desired waveform details.

The following is the schematic diagram of the acquisition memory. To easily understand the trigger event, we classify the acquisition memory 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 data). 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 currently displayed waveform).

MSO7000/DS7000 provides three trigger modes: Auto, Normal, and Single. The default is Auto.
In the trigger control area (Trigger) on the front panel, press Mode to quickly switch the current trigger mode. The trigger mode is displayed at the upper-right corner of the screen: A (Auto), N (Normal), and S (Single).
Auto: In this trigger mode, if the specified trigger conditions are not found, triggers
are forced and acquisitions are made so as to display the waveforms. This trigger mode should be used when the signal level is unknown or the DC should be displayed as well as when forcible trigger is not necessary as the trigger condition always occurs.
Normal: In this trigger mode, triggers and acquisitions only occur when the specified
trigger conditions are found. This trigger mode should be used when the signal is with low repetition rate or only the event specified by the trigger setting needs to be sampled as well as when auto trigger should be prevented to acquire stable display.
Single: In this trigger mode, the oscilloscope performs a single trigger and
acquisition when the specified trigger conditions are found, and then stops. This trigger mode should be used when you need to perform a single acquisition of the specified event and analyze the acquisition result (you can pan and zoom the currently displayed waveform, and the subsequent waveform data will not overwrite the current waveform). After a single trigger mode is initiated, the operating status of the oscilloscope is in "STOP" state.
Note: In "Normal" and "Single" trigger modes, pressing Force can generate a
trigger signal forcibly.
In addition, you can enable the touch screen to set the trigger mode. Enable the
touch screen and tap the trigger setting label at the upper-right corner of the screen. Then the following window is displayed. Tap to select "Auto", "Normal", or "Single" as the trigger mode.

Trigger Coupling
Trigger coupling decides which kind of components will be transmitted to the trigger module. Please distinguish it from "Channel Coupling".
Note: Trigger coupling is only valid when the trigger type is Edge and the trigger
source is an analog channel.
Press Menu Coupling in the trigger control area (Trigger) on the front panel. Then, rotate the multifunction knob to select the desired coupling mode (by
default, it is DC). You can also press Coupling continuously to select it or enable the touch screen to select the desired coupling mode with touch gestures.
DC: allows DC and AC components to pass the trigger path. AC: blocks the DC components and attenuates signals. LFR: blocks the DC components and rejects the low-frequency components. HFR: rejects the high frequency components.
Trigger Holdoff
Trigger holdoff can be used to stably trigger on complex repetitive waveforms that have multiple edges (or other events) between waveform repetitions (such as pulse series). Holdoff time indicates the time that the oscilloscope waits for re-arming the trigger module after generating a correct trigger. The oscilloscope will not trigger even if the trigger condition is met during the holdoff time and will only re-arm the trigger module after the holdoff time expires.
For example, to stably trigger the repetitive pulse series as shown in the figure below, the holdoff time should be set to a value that is greater than t1 and smaller than t2.

default, the holdoff time is 16 ns). Also, you can use the numeric keypad to set the holdoff time. The adjustable range of holdoff time is from 8 ns to 10 s.
Noise Rejection
Noise rejection can reject the high frequency noise in the signal and reduce the possibility of miss-trigger of the oscilloscope.
In the trigger control area (Trigger) on the front panel, press Menu to enter the trigger setting menu, then press Noise Reject continuously (for some trigger,
Noise Reject is a sub menu under More, at this time, press Menu More Noise Reject) to enable or disable noise rejection.

You can also press Type continuously to select the trigger type or enable the touch screen to tap the desired trigger type and select it.
Source Selection:
Press Source to open the signal source list and select CH1-CH4 or D0-D15. For details, refer to descriptions in "Trigger Source". The current trigger source is displayed at the upper-right corner of the screen.
Note: Only when we select the channel (that has been input with signals) as the
trigger source, can we obtain a stable trigger.
Edge Type:
Press Slope and rotate the multifunction knob to select the edge type of the input signal that starts to pass through the trigger level. You can also press Slope continuously to enable the touch screen to select the edge type.
Rising: starts timing when the rising edge of the input signal passes through
the trigger level. Falling: starts timing when the falling edge of the input signal passes
through the trigger level.
Either: starts timing when either edge of the input signal passes through the
trigger level.
Timeout Value:
Timeout value represents the maximum time that the signal remains idle before the signal passes through the trigger level. Press Timeout, and then rotate the multifunction knob or use the pop-up numeric keypad to set the timeout value of Timeout trigger. The available range is from 16 ns to 10 s.

Polarity: Press Polarity continuously to select the pulse polarity of Runt trigger.
Positive: triggers on the positive runt pulse. Negative: triggers on the negative runt pulse.
Trigger Condition:
Press When and rotate the multifunction knob to set the trigger conditions of Runt trigger. You can also press When continuously or enable the touch screen to select it.
None: indicates not setting the trigger condition of Runt trigger. >: triggers when the runt pulse width is greater than the lower limit of pulse
width. Press Lower to set the minimum pulse width of Runt trigger. <: triggers when the runt pulse width is smaller than the upper limit of pulse
width. Press Upper to set the maximum pulse width of Runt trigger. <>: triggers when the runt pulse width is greater than the lower limit and
smaller than the upper limit of pulse width. Press Upper to set the maximum
pulse width of Runt trigger. Press Lower to set the minimum pulse width of
Runt trigger.
Note: The lower limit of the pulse width must be smaller than the upper limit.
Level Selection and Adjustment of Trigger Level:
After the trigger condition setting is completed, you need to adjust the trigger level to correctly trigger the signal and obtain a stable waveform. Press Level Select (when "<>" is selected as the trigger condition, Level Select is a sub-menu under More), then rotate the multifunction knob to select the desired level type for adjustment, and then press down the knob to select the type. You can also press Level Select continuously to select the level type or enable the touch screen to tap the desired level type and select it. Level A: only adjusts the upper limit of the trigger level, and the lower limit of the trigger level remains unchanged. Level B: only adjusts the lower limit of the trigger level, and the upper limit of the trigger level remains unchanged. Level AB: adjusts the upper and lower limits of the trigger level at the same time, and the trigger level deviation (the difference between the upper limit and lower limit of the trigger level) remains unchanged.
Note: In Runt trigger, pressing Trigger LEVEL can quickly switch the current
level adjustment type.
Rotate the Trigger LEVEL knob to adjust the corresponding trigger level. During the adjustment of trigger level, two trigger level lines appear on the screen, and they move up and down with the change of the trigger level. At the same time, the real-time trigger level information is displayed at the lower-left corner of the screen (as shown in the figure below, H indicates the upper limit of the trigger level, L indicates the lower limit of the trigger level, and indicates the trigger level deviation). When you stopping modifying the trigger level, the trigger level line and
