2 To Set the Vertical System RIGOL 2 To Set the Vertical System The contents of this chapter: To Enable the Analog Channel Channel Coupling Bandwidth Limit Probe Input Impedance Waveform Invert Vertical Scale Vertical Expansion Amplitude Unit Channel Label Delay Calibration MSO4000/DS4000 User’s Guide 2-1
RIGOL 2 To Set the Vertical System To Enable the Analog Channel The MSO4000/DS4000 provides four analog input channels (CH1 to CH4) and provides independent vertical control system for each channel. As the vertical system setting methods of the four channels are completely the same, this chapter uses CH1 as the example. Connect a signal to the channel connector of CH1 and then press CH1 in the vertical control area (VERTICAL) at the front panel to enable CH1.
2 To Set the Vertical System RIGOL Channel Coupling Set the coupling mode to filter out the undesired signals. 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.
RIGOL 2 To Set the Vertical System Bandwidth Limit Set the bandwidth limit to reduce display noise. For example, the signal under test is a pulse with high frequency oscillations. When bandwidth limit is disabled, the high frequency components of the signal under test can pass the channel. Enable bandwidth limit and limit the bandwidth to 20 MHz, 100 MHz or 200 MHz, the high frequency components that exceed 20 MHz, 100 MHz or 200 MHz are attenuated.
RIGOL 2 To Set the Vertical System Probe This oscilloscope supports normal passive probes and active differential probes. It can automatically identify the type of the probe currently connected and the probe ratio. Press CH1 Probe to open the probe operation menu. 1. ProbeType Read the type of the probe currently connected as “Nor-Probe” or “DiffProbe”. Note that when a 50 Ω “DiffProbe” is used, the Input Impedance of the channel is set to “50 Ω” automatically. Normal Probe: such as RIGOL RP3500A.
RIGOL 2 To Set the Vertical System 3. Front-End RP7150 active probe provides “Single-end” and “Difference” probe heads. Press this softkey to select the desired probe head. 4. Probe-Cal Connect the differential probe to the channel input terminal (such as CH1) of the oscilloscope correctly, then connect the fast edge signal output from the [Trig Out/Calibration] connector at the rear panel of the instrument to the probe and CH2 respectively.
2 To Set the Vertical System RIGOL Input Impedance To reduce the circuit load caused by the interaction between the oscilloscope and the circuit under test, the oscilloscope provides two input impedance modes: 1 MΩ (default) and 50 Ω. 1 MΩ: at this point, the input impedance of the oscilloscope is very high and the current flows into the oscilloscope from the circuit under test can be ignored. 50 Ω: match the oscilloscope with devices with 50 Ω output impedance.
RIGOL 2 To Set the Vertical System Vertical Scale The vertical scale can be adjusted in “Coarse” or “Fine” mode. Press CH1 Volts/Div to select the desired mode. Rotate VERTICAL SCALE to adjust the vertical scale (clockwise to reduce the scale and counterclockwise to increase). The scale information (such as ) 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 current probe ratio.
2 To Set the Vertical System RIGOL Vertical Expansion SCALE to change the vertical scale of the analog When using VERTICAL channel, you can choose to expand or compress the signal vertically around the center of the screen or the ground point of the signal. Press Utility System VerticalExp to select “Center” or “Ground” and the default is “Ground”. Center: when the vertical scale is modified, the waveform will expand or compress around the center of the screen.
RIGOL 2 To Set the Vertical System Channel Label You can modify the labels used to mark the analog channels (CH1 to CH4) at the left side of the screen. The label is the number of the channel (such as ) by default and the length of the label can not exceed 4 characters. Press CH1 Label to enter the label modification interface as shown in the figure below. Name Input Area For example, change “ Keyboard ” to “ Upper/Lower Case Switch ”. Press Keyboard to select the “Keyboard” area.
RIGOL 2 To Set the Vertical System Delay Calibration When using an oscilloscope for actual measurements, the transmission delay of the probe cable may bring greater error (zero offset). The MSO4000/DS4000 allows users 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 below.
3 To Set the Horizontal System RIGOL 3 To Set the Horizontal System The contents of this chapter: Delayed Sweep Time Base Mode Horizontal Scale Horizontal Reference MSO4000/DS4000 User’s Guide 3-1
RIGOL 3 To Set the Horizontal System Delayed Sweep Delayed sweep can be used to enlarge a length of waveform horizontally to view the waveform details. Press MENU in the horizontal control area (HORIZONTAL) and press Delayed to enable or disable delayed sweep. Note that to enable delayed sweep, the current time base mode must be “Y-T” and the “Pass/Fail test” must be disabled.
RIGOL 3 To Set the Horizontal System In delayed sweep mode, the screen is divided into two display areas as shown in the figure below. The waveform before enlargement Main time base Delayed Sweep Time Base The waveform after enlargement The waveform before enlargement: The waveform in the area that has not been covered by the subtransparent blue in the upper part of the screen is the waveform before enlargement.
RIGOL 3 To Set the Horizontal System Time Base Mode Press MENU in the horizontal control area (HORIZONTAL) at the front panel and then press Time Base to select the time base mode of the oscilloscope and the default is Y-T. Y-T Mode This mode is the main time base mode and is applicable to CH1 to CH4. In this mode, the Y axis represents voltage and the X axis represents time. Note that only when this mode is enabled can Delayed Sweep be turned on.
RIGOL 3 To Set the Horizontal System X-Y Mode In this mode, the oscilloscope automatically turns on all four channels (CH1 to CH4) and the screen is divided into two coordinate areas. X1 and Y1 track the voltages of CH2 and CH1 and X2 and Y2 track the voltages of CH4 and CH3. The phase deviation between two signals with the same frequency can be easily measured via the Lissajous method. The figure below shows the measurement schematic diagram of the phase deviation.
RIGOL 3 To Set the Horizontal System The X-Y function can be used to measure the phase deviation 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. 2. 3. 4.
3 To Set the Horizontal System RIGOL When X-Y mode is enabled, Delayed Sweep will be disabled automatically. The following functions are not available in X-Y mode: Auto measure, cursor measure, math operation, reference waveform, delayed sweep, vector display, HORIZONTAL POSITION, trigger control, memory depth, acquisition mode, Pass/Fail test and waveform record.
RIGOL 3 To Set the Horizontal System Roll Mode In this mode, the waveform scrolls from the right to the left, much like a strip chart. This is useful for viewing slower signals as the signal is “drawn out” on the display as time elapses. The waveform horizontal position and trigger controls are not available. The range of horizontal scale adjustment is from 200.0 ms to 50.00 s.
RIGOL 3 To Set the Horizontal System Horizontal Scale Similar to “Vertical Scale”, the horizontal scale can be adjusted in “Coarse” or “Fine” mode. Press MENU ScaleAdjust in the horizontal control area (HORIZONTAL) at the front panel to select the desired mode. Turn HORIZONTAL SCALE to adjust the horizontal scale. Turn clockwise to reduce the horizontal scale and turn counterclockwise to increase.
RIGOL 3 To Set the Horizontal System Horizontal Reference The horizontal reference is the reference position according to which the screen waveform expands and compresses horizontally when adjusting HORIZONTAL SCALE. In Y-T mode (this function is not available in X-Y mode and Roll mode), press MENU HorRef in the horizontal control area (HORIZONTAL) to select the desired reference mode and the default is “Center”.
4 To Set the Sample System RIGOL 4 To Set the Sample System The contents of this chapter: Acquisition Mode Sample Mode Sample Rate LA Sample Rate Memory Depth Antialiasing MSO4000/DS4000 User’s Guide 4-1
RIGOL 4 To Set the Sample System Acquisition Mode The acquisition mode is used to control how to generate waveform points from sample points. Press Acquire Acquisition in the function menu at 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 Acquisition continuously to switch the acquisition mode. Normal In this mode, the oscilloscope samples the signal at equal time interval to rebuild the waveform.
4 To Set the Sample System RIGOL The Waveform before Average: The Waveform after 256 Averages: MSO4000/DS4000 User’s Guide 4-3
RIGOL 4 To Set the Sample System Peak Detect In this mode, the oscilloscope acquires the maximum and minimum values of the signal within the sample interval to get the envelope 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.
4 To Set the Sample System RIGOL Sample Mode This oscilloscope only supports real-time sampling. In this mode, the oscilloscope samples and displays waveforms within a trigger event. The maximum real-time sample rate of MSO4000/DS4000 is 4 GSa/s and the current sample rate is displayed under the Sa Rate menu. Tip Press RUN/STOP to stop the sample, the oscilloscope will hold the last display. At this point, you can still use the vertical control and horizontal control to pan and zoom the waveform.
RIGOL 4 To Set the Sample System Sample Rate Sample refers to the process that the oscilloscope converts analog signals to digital signals at a certain time interval and stores the data in order. Sample rate is the reciprocal of the time interval. Sample Rate = 1 /Δ t The analog channels sample rate of this oscilloscope is up to 4 GSa/s.
RIGOL 4 To Set the Sample System 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. The most common aliasing is the jitter on a fast edge. 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.
RIGOL 4 To Set the Sample System LA Sample Rate LA sampling refers to the process that the oscilloscope samples the compared digital signal at a certain time interval. LA sample rate is the reciprocal of the interval. For example, the oscilloscope with 1 GHz LA sample rate samples digital signals every 1 ns. The digital signal mentioned here refers to the signal generated by comparing the input signal with the threshold specified by users.
RIGOL 4 To Set the Sample System 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. MSO4000/DS4000 provides up to 140 M points memory depth.
RIGOL 4 To Set the Sample System Antialiasing At slower sweep speeds, the sample rate is reduced and a dedicated display algorithm is used to minimize the possibility of aliasing. Press Acquire Anti_aliasing to enable or disable the antialiasing function. By default, antialiasing is disabled. The displayed waveforms will be more susceptible to aliasing when this function is disabled.
5 To Trigger the Oscilloscope RIGOL 5 To Trigger the Oscilloscope The trigger system of an oscilloscope allows users to tailor data collection and isolate particular events by providing a flexible control system to “select” certain events (rising edge, falling edge, etc.).
RIGOL 5 To Trigger the Oscilloscope Trigger Source Press MENU Source in the trigger control area (TRIGGER) at the front panel to select the desired trigger source. Siganls input from CH1 to CH4, the [EXT TRIG] and [LOGIC D0-D15] connectors as well as the AC Line can all be used as trigger source. Analog channel input: Signals input from analog channels CH1 to CH4 can all be used as the trigger source. No matter whether the input of the channel selected is enabled, the channel can work normally.
RIGOL 5 To Trigger the Oscilloscope Trigger Mode The trigger mode affects the way in which the oscilloscope searches for the trigger. The following is the schematic diagram of the acquisition memory. As shown in the figure below, the position of the trigger event in the acquisition memory is determined by the reference time point and the delay setting.
RIGOL 5 To Trigger the Oscilloscope the data acquired just before the trigger. If no trigger is found, the oscilloscope will force a trigger. If the forced trigger is invalid, the oscilloscope still displays waveform but the waveform will not be stable. If the forced trigger is valid, the oscilloscope displays a stable waveform. This trigger mode is applicable to low-repetitive-rate signals and unknown signal levels. To display DC signals, you must use auto trigger mode.
5 To Trigger the Oscilloscope RIGOL Trigger Coupling The trigger coupling setting determines the type of signal components that will be transmitted to the trigger circuit. This is similar to the settings of “Channel Coupling” but is specific to the triggered signal only. DC: allow DC and AC components into the trigger path.
