In this setting, it disconnects the input signal. The screen displays as Figure 2-5: GND coupling setup GND coupling status symbol Figure 2-5 © Copyright RIGOL Technologies, Inc. 2007.
RIGOL 2. Set up the channel bandwidth limit To use CH1 as an example, input a signal that contains high frequency component. Press CH1→BW Limit→OFF, to set up bandwidth limit to “OFF” status. The oscilloscope is set to full bandwidth and the high frequency component in the signal will pass. The waveform is displayed as Figure 2-6: Turn off the BW limit Figure 2-6 Press CH1→BW Limit→ON, to set up bandwidth limit to “ON” status. It will reject the frequency component higher than 20MHz.
RIGOL 3. Probe Attenuation Setting When using a probe, the oscilloscope allows you to select the attenuation factor for the probe. The attenuation factor changes the vertical scaling of the oscilloscope so that the measurement results reflect the actual voltage levels at the probe tip. To change (or check) the probe attenuation setting, press the CH1 or CH2 button (according to which channel you are using), toggle the Probe soft button to change the attenuation factor to match the probe you are using.
RIGOL 4. Volts/Div settings The Volts/Div control has Coarse or Fine configuration. The Vertical Sensitivity is 2mv-5V/div. Coarse: It is the default setting of Volts/Div, and it makes the vertical scaling in a 1-2-5-step sequence from 2mV/div, 5mV/div, 10mV, to 5 V/div. Fine: This setting changes the vertical scale to small steps between the coarse settings.
RIGOL 5. To invert a waveform Invert turns the displayed waveform 180 degrees, as respect to the ground level. When the oscilloscope is triggered on the inverted signal, the trigger is also inverted. Figure 2-10 and 2-11 show the changes after inversion.

RIGOL Ⅱ. Math functions The mathematic functions include “add”, “subtract”, “multiply” and “FFT” for CH1 and CH2. The mathematic result can also be measured by grid and cursor.
RIGOL I. Using the FFT The FFT (Fast Fourier Transform) process mathematically converts a time-domain signal into its frequency components.
RIGOL Key points for FFT 1 Signals that have a DC component or offset can cause incorrect FFT waveform component magnitude values. To minimize the DC component, choose AC Coupling on the source signal. 2 To reduce random noise and aliases components in repetitive or single-shot events, set the oscilloscope acquisition mode to average. 3 To display FFT waveforms with a large dynamic range, use the dBVrms scale. The dBVrms scale displays component magnitudes using a log scale.
RIGOL Selecting an FFT Window DS1000 series oscilloscopes provide four FFT windows. Each window is a trade-off between frequency resolution and amplitude accuracy. What you want to measure and your source signals characteristics help determine which window to use. Use the following guidelines to select the best window. Table2-7 Window Rectangle Hanning Hamming Blackman Features Best for measuring Best frequency Resolution and worst magnitude resolution. This is essentially the same as no window.

The resolution of the knob changes according to the change of the vertical level (The digital channels of Mixed Signal Oscilloscope changes according to the changes of the waveforms displayed). Pressing this knob will clear the channel offset to zero.
RIGOL Understand the Horizontal System The oscilloscope shows the time per division in the scale readout. Since all active waveforms use the same time base, the oscilloscope only displays one value for all the active channels, except when you use Delayed Scan, or Alternative Trigger. The horizontal controls can change the horizontal scale and position of waveforms. The horizontal center of the screen is the time reference for waveforms.

Key Points Y-T: The conventional oscilloscope display format.
RIGOL Delayed Scan: The Delayed Scan is a magnified portion of the main waveform window. You can use Delayed Scan to locate and horizontally expand part of the main waveform window for a more detailed (higher horizontal resolution) analysis of signal. Use Delayed Scan to expand a segment of a waveform to see more details. The Delayed Scan time base setting cannot be set slower than the Main time base setting.
RIGOL and position of the Delayed Scan. The symbol at bottom of the screen means the main time base and the symbol on the center bottom means the Delayed Scan time. z Use the horizontal portion. z Turn the horizontal z To change the main time base, you must turn off the Delayed Scan mode. z Since both the main and Delayed Scan are displayed; there are half as many vertical divisions so the vertical scaling is doubled. Notice the changes in the status bar.
RIGOL X-Y Format This format is useful for studying phase relationships between two signals. Channel 1 in the horizontal axis(X) and channel 2 in the vertical axis(Y), the oscilloscope uses a none-trigger acquisition mode, data is displayed as dots. . Figure 2-40: X-Y display format The following modes or functions will not work in X-Y format.
RIGOL Understand the Trigger System The trigger determines when the oscilloscope starts to acquire data and display a waveform. When a trigger is set up properly, it can convert unstable displays or blank screens into meaningful waveforms. When the oscilloscope starts to acquire a waveform, it collects enough data so that it can draw the waveform to the left of the trigger point. The oscilloscope continues to acquire data while waiting for the trigger condition to occur.
RIGOL Trigger Modes The oscilloscope provides seven trigger modes: Edge, Pulse, Slope, Video, Alternative, Pattern (only for mixed signal oscilloscopes) and Duration trigger (only for mixed signal oscilloscopes). Edge: An edge trigger occurs when the trigger input passes through a specified voltage level in the specified slope direction. Pulse: Use this trigger type to catch pulses with certain pulse width. Video: Use video trigger on fields or lines for standard video signals.
RIGOL Settings for Edge Trigger An edge trigger determines whether the oscilloscope finds the trigger point on the rising or the falling edge of a signal. Select Edge trigger Mode to trigger on Rising edge, falling edge or rising & falling edge.
RIGOL Settings for Pulse Width Trigger Pulse trigger occurs according to the width of pulse. The abnormal signals can be detected through setting up the pulse width condition.

RIGOL Pattern Trigger (Mixed Signal Oscilloscope) Pattern trigger identifies trigger terms by checking appointed code. The code is logical relationship of all channels, with high (H), low (L) and ignore(X).
RIGOL Duration Trigger (Mixed Signal Oscilloscope) Trigger in appointed time when code terms are satisfied.
RIGOL Key Points: H (High): Logic high: voltage is higher than threshold setting. L (Low): Logic low: voltage is lower than threshold setting. X (Ignore): Don’t care. If all the channels are ignored, the oscilloscope won’t be triggered. Qualifier: A timer begins when code terms are satisfied. Duration trigger occurred in the time set by the qualifier. 2-52 © Copyright RIGOL Technologies, Inc. 2007.
RIGOL Trigger Settings In trigger set up menu, you can set up different trigger settings according to different trigger modes. When in the mode of Edge and Pulse, the source is D15-D0 (Mixed Signal Oscilloscope), only Holdoff is adjustable. When source is non-digital channel and in slope trigger, only trigger coupling, trigger sensitivity and Holdoff can be set. For video trigger, Sensitivity and Holdoff can be set.

RIGOL Trigger Holdoff Trigger Holdoff can stabilize complex waveform, such as the pulse range. Holdoff time is the oscilloscope’s waiting period before starting a new trigger. During Holdoff, oscilloscope will not trigger until Holdoff ends. For instance: To trigger on the first pulse on a group of them, users can set the holdoff time to Pulse cluster width. Trigger site Trigger holdoff Time of holdoff Figure 2-65: Trigger Holdoff To use trigger Holdoff: 1.
RIGOL Trigger Key points 1. Trigger Source: Trigger can occur from several sources: Input channels (CH1, CH2 and D15-D0 on mixed signal oscilloscopes), AC Line, Ext, Ext/5. z CH1 or CH2: It is the most commonly used trigger source. The channel will work when selected as a trigger source whatever displayed or not. z Ext Trig: The instrument can trigger from a third source while acquiring data from CH1 and CH2.
RIGOL Trigger, such as the output of Power supply. NOTE: When horizontal control is set under 50 ms/div, Auto mode allows the oscilloscope don’t capture trigger signal. z Normal: The Normal mode allows the oscilloscope to acquire a waveform only when it is triggered. If no trigger occurs, the oscilloscope keeps waiting, and the previous waveform, if any, will remain on the display. z Single: In Single mode, after pressing the RUN/STOP key, the oscilloscope waits for trigger.
RIGOL Adjustable trigger sensitivity z To avoid the influence of noise from the physical world, and get the stable trigger, the trigger circuit has adopted Stickiness. In DS1000 series, the stickiness is adjustable from 0.1div-1.0div, which means when it sets to 1.0div, the trigger circuit will not affect any signal with peak-peak amplitude less than 1.0div, so as to avoid the influence of the noise. 2-58 © Copyright RIGOL Technologies, Inc. 2007.
RIGOL To Set Up the Sampling System As Figure 2-66 displays, the Acquire button for sampling system is at the MENU Acquire setup button Figure 2-66 Use Acquire button to pop up the menu as follows: Figure 2-67 Table 2-41 Menu Settings Comments Acquisition Normal Average Peak Detect Normal Acquisition mode Average Acquisition mode Peak Detect Acquisition mode Averages 2 to 256 Step by multiple of two.
