RIGOL 5. Volts/Div settings The Volts/Div control has Coarse or Fine configuration. The Vertical Sensitivity is 1mv/div ~10V/div. Coarse: It is the default setting of Volts/Div in a 1-2-5-step sequence from 1mV/div, 2mV/div, 5mV/div, 10mV/div to10 V/div. Fine: This setting changes the vertical scale to small steps between the coarse settings. It will be helpful to adjust the waveform in smooth steps.
RIGOL 6. 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 2-13 and 2-14 show the changes before after the inversion respectively.
RIGOL Math functions The mathematic functions include “Add”, “Subtract”, “Multiply” and “FFT” for Channel 1 and Channel 2. The mathematic result can be measured by the grid and the cursor. Press MATH button to enter “Math” menu, meanwhile, sign of math scale will appear under the screen. See figure below, waveform of channel1 is marked yellow, waveform of channel2 is marked blue, and waveform of channel1 adding channel2 is marked purple.
RIGOL 1. FFT Analyse The FFT (Fast Fourier Transform) process converts a time-domain signal into its frequency components mathematically. FFT waveforms are useful in the following applications: Measuring harmonic content and distortion in systems Characterizing noise in DC power supplies Analyzing vibration Press MATH→Operate→FFT to enter FFT setting menu. Figure 2-17 Table 2-7 The FFT menu Menu Settings Comments Operate A+B A-B A× B FFT Add source A to source B.
RIGOL 2. Selecting an FFT Window Oscilloscope record the FFT change for a limit time assume that YT waveform repeat ceaselessly. If cycle is integer, YT waveform voltage is the same at starting and ending point, and waveform is consecutive. Contrary, If cycle is non-integer, the voltage is different at starting and ending point, leading to the high frequency instantaneous intermit, which is called “leak”. To avoid leak, multiply a window function to force the value is 0 at starting and ending point.
RIGOL Term Explanations FFT Resolution: The quotient between sampling rate and number of FFT points. With a fixed FFT points, the lower sampling rate results in better resolution. Nyquist Frequency The highest frequency that any real-time digitizing oscilloscope can acquire without aliasing. It‟s normally half of the sample rate. This frequency is called the Nyquist frequency. Frequency above the Nyquist frequency will be under sampled, causing a situation known as aliasing.

Y-T Y-axis indicates vertical voltage, X-axis indicates horizontal time. Y-axis indicates voltage of CH2, X-axis indicates voltage of CH1. The waveform display updates from right to left. X-Y Roll[1] Trig-offset Reset Comments Reset Adjust to the center.
RIGOL The Horizontal Knobs The horizontal controls change the horizontal scale and position of waveforms. The horizontal center of the screen is the time reference for waveforms. Changing the horizontal scale causes the waveform to expand or contract with respect to the screen center. Horizontal position changes the displayed waveform position, relative to the trigger point. 1. Horizontal knob is used to adjust the horizontal position of all channel (include Math) waveforms.
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. Press MENU→Delayed→ON, or press horizontal scan function. See the waveform below.
RIGOL X-Y Format This format is useful for studying phase relationships between two signals. CH1 in the horizontal axis(X) and CH2 in the vertical axis(Y), the oscilloscope uses a none-trigger acquisition mode, data is displayed as dots. Press MENU→Time Base→X-Y to enter X-Y mode. Figure 2-33 X-Y display format The oscilloscope could capture waveform with arbitrary sample rate in Y-T mode (2GSa/s maximum for single channel, 1GSa/s maximum for double channels).
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 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. Press MENU→Mode→Edge to enter the following menu.

RIGOL Trigger Settings Set up different trigger settings according to different trigger modes. When in the mode of Edge and Pulse, 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 Use trigger Holdoff to stabilize a complex waveform, such as a 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.
RIGOL Trigger Terms Explanation 1. Trigger Source: Trigger occurs from several sources: Input channels (CH1 and CH2), AC Line, Ext, Ext/5. Input Channels: It is the most commonly used trigger source. The channel works when selected as a trigger source whatever displayed. 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 occur, the display becomes stable on the screen. Any factor results in the un-stability of waveforms can be detected by Auto 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.
RIGOL 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 DS1000CA 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.
RIGOL To Set Up the Sampling System Figure 2-55 shows the menu button for acquire system on the front panel.

This mode would make the screen refresh slower. To Avoid signal aliasing, select Peak Detect Acquisition. Select Real-time acquisition to observe the single-shot or pulse signals. Select Equ-Time to observe high frequency repetitive signals.
RIGOL Figure 2-59 Adopt Normal acquisition Figure 2-60 Adopt peak detect acquisition, signal contains envelope Key points Stop Acquisition: When the scope is acquiring waveforms, the waveforms is in a live status; when acquisition is stopped, frozen waveform will be displayed, the position and scale can still be adjusted by vertical control and horizontal control.
RIGOL Term Explanations Real-time Sampling: DS1000CA has Real-time sampling rate up to 2GSa/s. At the time base 20ns 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 20ps of horizontal resolution (equivalent 50Gsa/s). This mode is good for observing repetitive signals, and it is not recommended for single-shot or pulse. Normal Acquisition: Oscilloscope acquires signal by equal time interval.
