RIGOL Turn on/off Channels The CH1, CH2, Ext. Trigger and LA (DS1000D series) channels are input channels. All functionalities applied will be based on operating the instrument with channels. So MATH and REF can be regarded as relatively isolated channels. To turn on/off any one of the channels, press the corresponding button on the front panel. The key backlight indicates the channel is currently active. Press the button again to turn the channel off.
RIGOL Set up Vertical Position and Scale You can use the vertical controls to display waveforms, adjust vertical and , and set input parameters. 1. Using vertical knob. The vertical control changes the position of signal waveforms in all channels (including MATH and REF). The resolution changes according to the vertical level set. Pressing this knob will clear the channel offset to zero. (The function is available for DS1000D series, but not includes digital channel.) 2. Using vertical knob.
RIGOL To Set up 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 using 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.
RIGOL Figure 2- 37 Table 2- 19 The Horizontal menu Menu Delayed Time Base Settings Comments ON OFF Turn on Delayed Scan mode Turn off the Delayed Scan mode Y-T Show the relative relation between vertical voltage and horizontal time. Show CH1 value at X axis; CH2 value at Y axis. In Roll Mode, the waveform display updates from right to left.
RIGOL Marks Indicator ① The current waveform window’s position in the memory. ② The trigger position in the memory. ③ The trigger position in the current waveform windows. ④ The horizontal time base (main time base). ⑤ The trigger’s horizontal offset according to the center of the window. Key Points Y-T: The conventional oscilloscope display format. It shows the voltage of a waveform record (on the vertical axis) as it varies over time (on the horizontal axis).
RIGOL Delayed Scan: The Delayed Scan is a magnified portion of the main waveform window. Use Delayed Scan to locate and horizontally expand part of the main waveform window for a more detailed (higher horizontal resolution) analysis of signal. The Delayed Scan time base setting cannot be set slower than the Main time base setting.
RIGOL value on the center bottom means the Delayed Scan time. Use the horizontal portion. knob to change the position of the expanded Use the horizontal To change the main time base, turn off the Delayed Scan mode. 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. knob to adjust the Delayed Scan resolution.
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 NOTE：In Y-T format, all sample rates are available. But in X-Y format, 100 MSa/s is not available. In common, deceasing the sample rate can display the wavefrom better.
RIGOL To Set up 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 DS1000D series) and Duration trigger (only for DS1000D series). 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 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. 2. 3. 4.
RIGOL Trigger Key points 1. Trigger Source: Trigger can occur from several sources: Input channels (CH1 and CH2), AC Line, Ext. CH1 or CH2: It is the most commonly used trigger source. The channel works when selected as a trigger source whatever displayed or not. Ext Trig: The instrument can be triggered from a third source while acquiring data from CH1 and CH2. For example, to trigger from an external clock or with a signal from another part of the test circuit.
RIGOL Trigger, such as the output of Power supply. NOTE: When horizontal control is set under 50 ms/div, Auto mode allows the oscilloscope not to capture trigger signal. 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. Single: In Single mode, after pressing the RUN/STOP key, the oscilloscope waits for trigger.
RIGOL This feature is very useful to study the events that led up to the trigger point. Everything to the right of the trigger point is called post-trigger information. The delay range (pre-trigger and post-trigger information) depends on the sweep speed selected. 5. Adjustable trigger sensitivity To avoid the influence of noise from the physical world, and get the stable trigger, the trigger circuit has adopted Stickiness. In DS1000E, DS1000D series, the stickiness is adjustable from 0.1div-1.

RIGOL Key Points Real-time Sampling: The oscilloscope has Real-time sampling rate up to 1GSa/s. At the time base 50ns or faster, the oscilloscopes use the sine(x)/x interpolation to expand the horizontal time base. Equivalent sampling: Known as Repetitive sampling to get up to 40ps of horizontal resolution (equivalent 25Gsa/s). This mode is good for observing repetitive signals, and it is not recommended for single-shot or pulse. Normal: Oscilloscope acquires signal by equal time interval.
