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. The adjustable range of the vertical scale is from 500 µV/div to 1 0 V /di v.
When CH1 is turned on, you can adjust the vertical scale with the following three methods: Rotate Vertical
(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

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

Timebase Mode

MSO5000-E series supports three available timebase modes: YT mode, XY mode, and ROLL mode. By default, the timebase m o d e i s Y T.
Press Acquire Timebase Mode on the front panel, and then rotate the multifunction knob to select the desired timebase 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 timebase 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.
Figure 4-1 Measurement Schematic Diagram of Phase Deviation
4-2 MSO5000-E User Guide
Chapter 4 To Set the Sample System RIGOL
According to sinθ=A/B or C/D, θ 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:
θ=±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: 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.

Note:
In XY mode, CH1 and CH2 are forced to be enabled. The maximum sample rate
in XY mode is 2 GSa/s. 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", "To Select the Display Type", "Scale", "Protocol Decoding", "Pass/Fail Test", "Waveform Recording & Playing", and "Digital Channel".

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.

Acquisition Mode

The acquisition mode is used to control how to generate waveform points from the sample points.
MSO5000-E supports the following four acquisition modes: Normal, Average, Peak, and High Resolution. 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 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.

Peak

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 that might be lost. In this mode, signal aliasing can be prevented, but the noise displayed would be larger.
In this mode, the oscilloscope can display all the pulses whose pulse widths are at least the same 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 waveform on the screen and improves the vertical resolution. This is generally used when the sample rate of the digital converter is greater than the

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.

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.
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

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.
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

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 GSa/s, and its display value is related to the sample rate of the current analog channel.
Note:
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.
LA sample rate is displayed under the LA SampleRate menu. To indirectly

LA Memory Depth

Press Acquire More to view the memory depth of the current digital channel under LA Mem Depth. The LA memory depth will change with the memory depth of the analog channel, and cannot be set separately. The maximum LA memory depth is 25 Mpts.

Anti-Aliasing

At a slower sweep speed, the sample rate is reduced, and a dedicated display algorithm can be used to minimize the possibility of aliasing.
Press Acquire Anti-aliasing to enable or disable the anti-aliasing function. By default, anti-aliasing is disabled. In this case, it is more likely to generate waveform aliasing.
Note: This function should be enabled when the horizontal timebase has a large

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 timebase 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.

Analog channels (CH1-CH2), digital channels (D0-D15), E X T, EXT/5, or AC Line can all be selected as the trigger source.
Analog channel input:
Signals input from analog channels CH1-CH2 can all be used as trigger sources. No matter whether the channel selected is enabled, the channel can work normally.
Digital channel input:
Signals input from digital channels D0-D15 can all be used as trigger sources. No matter whether the channel selected is enabled, the channel can work normally.
External trigger input:
The external trigger source can be used to trigger on the third channel while all the other two channels are acquiring data. The trigger signal (e.g. external clock or signal of the circuit under test) will be connected to EXT or EXT/5 trigger source via the external trigger input terminal [EXT] connector. You can set the trigger conditions within the range of the trigger level (from -1 V to +1 V for EXT or from -5 V to +5 V for EXT/5).
AC line input:
The trigger signal is obtained from the AC power input of the oscilloscope. AC trigger is usually used to measure signals relevant to the AC power frequency. For example, stably triggering the waveform output from the transformer of a transformer substation. It is mainly used in related measurements of the power industry.

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).

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.

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.

Pattern Trigger

Identifies a trigger condition by searching for a specified pattern. This pattern is a logical "AND" combination of channels. Each channel can be set to H (high), L (low), or X (don't care). A rising or falling edge (you can only specify a single edge) can be specified for one channel included in the pattern. When an edge is specified, the oscilloscope will trigger at the edge specified if the pattern set for the other channels are true (namely the actual pattern of the channel is the same as the preset pattern). If no edge is specified, the oscilloscope will trigger on the last edge that makes the pattern true. If all the channels in the pattern are set to "X", the oscilloscope will not trigg e r.
