Vertical Scale

Value Input Field Decrease Increase

To Adjust the Vertical Scale

Vertical scale indicates the v olt age value per grid in the vertical axis of the screen. It is often expressed in V/div. While you adjust the vertical s cale, the display a mplitude of the waveform wo uld enlarge or red uce. The s cale information of the channel status label (e.g. as show n 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 10 V/div.

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 gestu re on the touch screen . For details, refer to the "Pinch & Stretch" section.

 Enable the touch screen f unction , an d t ap the channel status label at the bot to m

 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.

To Adjust the Vertical Offset

Vertical offset indicates the offset of the signal ground level position of the w a vef orm 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 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).

Channel Coupling

The undesired signals can be filtered out by setting the coupling mode. Fo r example , the signal under test is a square waveform with DC offset.  When the coupling mode is "DC": the DC a nd AC comp onents of the si gnal under

test can both pass the channel.

 When the coupling mode is "AC": the DC components of the signal under test

are blo cked.

 When the coupling mode is "GND", the DC and AC components of the signal

under test are both 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.

Bandwidth Limit

MSO5000 series supports the bandwidth limit function. Setting the bandwidth limit can reduce the noises in the displayed wa veforms. F or 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 you enable the bandwidth limit and limit it to 20 MHz, 100 MHz, or 200

MHz, the high frequency components found in the signal under test that are greater than 20 MHz, 100 MHz, or 200 MHz are attenuated.

Press 1 to open the setting menu of CH1.Then, press BW Limit continuously or rotate the multifunction knob to select the desired bandwidth limit. Press down

the knob to select it. By default, it is OFF. When the bandwidth limit is enabled, the character "B" will be displayed in the channel s tatus label at the bot tom of the screen,

To Adjust the Horizontal Time Base

Horizontal time base, also called the horizontal scale, refers to the time of each grid in the horizontal direction of the screen. It is usually expressed in s/div. The adjustable range of the horizontal time base is related to the model type.

While you change the horizontal time base, the displayed waveforms of all channels are expanded or compressed horizontally relative to the current selected horizontal reference baseline (refer to "Horizontal Expansion"). The horizontal time base at the upper-left corner of the screen will be changed accordingly, as shown in the figure below.

You can adjust the horizontal time base with the following three methods:  Rotate Horizontal

available range (clockwise to red uce the horizontal time base and counterclockwise to increase).

 Enable the touch screen function and adjust the horizontal time base 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 horizontal time base label

at the top of the screen. The following window is displayed. Tap the

Timebase Mode

MSO5000 series supports three available time base modes: YT mode, XY m ode, 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.

Figure 4-1 Measurement Schematic Diagram of Phase Deviation

4-2 MSO5000 User's 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 a bove 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 th at corresponds to CH1 and CH 2 respectively to make the signals easy to observe. Then, a circle, as shown in the figure below, should be displayed.

But due to the limitation of the memory depth, you have to reduce the waveform sample rate to ac quire a lo nger wave form (refe r to the int roduction in "Memory Depth").

Acquisition Mode

The acquisition mode is used to control how to generate waveform points from the sample points.

MSO5000 supports the following four a cquisition modes: Normal, Aver age, Peak, and High Resolution. By default, the acquisition mode is Normal.

Press Acquire  Acquisition on the front pa nel, a nd then rotate the multif u nction knob to select the desired acquisition mode. Then, press down the knob to

select the mode. You can also press Acquisition continuously to s elect the mode or enable the touch screen to tap the desired mode and select it.

Normal

In this mode, the oscillosc ope sam ples 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 t he vertic al resol ution; 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 s maller than t he one y ou in put an d t he 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.

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.

Sample Rate

Sampling is the process of converting the analog signal into the digital signal at a specif ied 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 8 GSa/s. The maximum real-time sample rate in the half-channel mode is 4 GSa/s, and the maximum real-time sample rate in the all-channel mode is 2 GSa/s.

The impact of low sample rate on the waveform:

1. Waveform Distortion: when the sample rate is too low, some waveform detail s are lost, a nd the sample waveform dis played is rather different f ro m 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 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 ti me interval. F or example, if the LA sample rate is 500 MSa/s, it indicates that the oscilloscope will make data acquisition on the digital si gnals at an interv al of 2 ns . The maximum LA sample rate of the oscilloscope is 1 GSa/s, an d 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.

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.

After the system runs, t he 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 sample d will still be trans mitt ed to the pre-trig ger buffer (the new data will continuously ove rwrite the previous data). When a trig ger 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).

 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.

When "AC" or "LFR" is selected under Coupling, no trigger level lines and trigger icons are displayed. When you adjust the trigger level, you can only see the changes

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 t he 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 trig ger the repetitive pulse series as s hown in t he figure below , the holdoff time should be set t o a value that is greate r than t1 and smaller than t2.

Figure 5-2 Schematic Diagram of Trigger Holdoff

In the trigger control area (Trigger) on the fron t pan el , press Menu  Holdoff (for some triggers, Holdoff is a sub menu under More, at this tim e, press Menu  More  Holdoff) and then rotate the multifunction knob at a small step to modify the holdoff time (the holdoff to this time when the waveforms are stably triggered; by default, the holdoff time is 16 ns). Also, you can use the numeric keypad to s et 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 triggers,

Noise Reject is a sub menu under More, at this time, press Menu  More  Noise Reject) to enable or disable noise rejection.

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 t o H (hig h), L ( low), or X (don't care). A rising or falling edge (you can only specify a single edge) can be specif ied for one channel included in the pattern. When an edge is specified, the oscilloscope will trigger at the edge s pecified if the patt ern set f or the other channels are true (namely the actual pat tern of the channel is the same as the p reset pattern). If no edge is specified, the oscilloscope will trigger on the last edge that makes the pattern true. If all the ch annels in t he pat tern a re s et to "X", the oscilloscope will not trigger.
