SIGLENT Vertical System This chapter introduces how to set the vertical system of the oscilloscope.
SIGLENT Enable the Channel The oscilloscope provides 2 analog input channels and provides a vertical control system for each channel. As the vertical system setting methods are the same, this chapter takes CH1 as an example to introduce the setting method of the vertical system. Connect a signal to the CH1 channel input connector; and then press the CH1 button in the vertical control area (Vertical) on the front panel to enable CH1.
SIGLENT Vertical Scale The vertical scale can be adjusted in Coarse or Fine mode. Coarse adjustment (take counterclockwise as an example): Set the vertical scale in 1-2-5 steps namely 500 uV/div, 1 mV/div, 2 mV/div, 5 mV/div, 10 mV/div …10 V/div. Fine adjustment: Further adjust the vertical scale within a relatively smaller range to improve vertical resolution. For example: 2 V/div, 1.98 V/div, 1.96 V/div, 1.94 V/div …1 V/div.
SIGLENT Vertical Position Turn the Vertical Position Knob to adjust the vertical position of the channel waveform. Turn the knob clockwise to increase the vertical position (the channel waveform moves up) while counterclockwise will reduce the vertical position (the waveform moves down). Push the knob to set the vertical position of the channel waveform to zero. During the adjustment, the vertical position information Volts Pos displays at the bottom of the screen.
SIGLENT Coupling Set the coupling mode to filter out undesired signals. For example, the signal under test is a square waveform with DC offset. When the coupling mode is set to DC: The DC and AC components of the signal under test can both pass the channel. When the coupling mode is set to AC: The DC components of the signal under test are blocked. When the coupling mode is set to GND: The DC and AC components of the signal under test are both blocked.
SIGLENT Probe Set the probe attenuation factor to match the type of the probe that you are using to ensure correct vertical readouts. Press the CH1 button on the front panel; then press the Probe softkey and turn the Universal Knob to select the desired value and push the knob to confirm. The default setup is 1X. The current probe attenuation factor is displayed in the channel label at the right side of the screen. You can also press the Probe softkey continuously to switch the probe attenuation factor.
SIGLENT Unit Select the amplitude display unit for the current channel. The available units are volts denoted by “V” and amps shown as “A”. When the unit is changed, the unit displayed in the channel label will change accordingly. 1. Press CH1 button on the front panel to enter the CH1 function menu. 2. Press the Next Page softkey to enter the second page of the CH1 function menu. 3. Press the Unit softkey to select the desired unit V or A. The default setup is V.

Press the Next Page softkey to enter the second page of the CH1 function menu. 3. Press the Trace softkey to visible or hidden the channel waveform.
SIGLENT Horizontal System This chapter introduces how to set the horizontal system of the oscilloscope.
SIGLENT Horizontal Scale Turn the Horizontal Scale Knob on the front panel to adjust the horizontal time base. Turn clockwise to reduce the horizontal time base and turn counterclockwise to increase. The time base information at the upper left corner of the screen will change accordingly during the adjustment. The range of the horizontal scale is from 500 ps/div to 100 s/div. The Horizontal Scale Knob works (in the Normal time mode) while acquisitions are running or when they are stopped.
SIGLENT Trigger Delay Turn the Position Knob on the front panel to adjust the trigger delay of the waveform. During modification, all waveforms will move left or right and the trigger delay message at the upper-right corner of the screen will change accordingly. Press down this knob to quickly reset the trigger delay. Changing the delay time moves the trigger point (solid inverted triangle) horizontally and indicates how far it is from the time reference point.
SIGLENT Roll Press the Roll button to enter the roll mode. In the Roll mode the waveform moves slowly across the screen from right to left. It only operates on time base settings of 50 ms/div and slower. If the current time base setting is faster than the 50 ms/div limit, it will be set to 50 ms/div when Roll mode is entered. If you would like to stop the display in Roll mode, press the Run/Stop button. To clear the display and restart an acquisition in Roll mode, press the Run/Stop button again.
SIGLENT Zoom Zoom is a horizontally expanded version of the normal display. You can use Zoom to locate and horizontally expand part of the normal window for a more detailed (higher resolution) analysis of signals. Press the Horizontal Scale Knob on the front panel to turn on the zoom function, and press the button again to turn off the function. When the Zoom function is on, the display divides in half.
SIGLENT To change the time base of the normal window, turn off Zoom; then, turn the Horizontal Scale Knob.
SIGLENT Sample System This chapter introduces how to use the run control and set th e sampling system of the oscilloscope.
SIGLENT Run Control Press the Run/Stop or Single button on the front panel to run or stop the sampling system of the scope. When the Run/Stop button is green, the oscilloscope is running, that is, acquiring data when trigger conditions are met. To stop acquiring data, press the Run/Stop button. When stopped, the last acquired waveform is displayed. When the Run/Stop button is red, data acquisition is stopped.
SIGLENT Overview To understand the oscilloscope's sampling and acquisition modes, it is helpful to understand sampling theory, sample rate, oscilloscope bandwidth and sample rate. Sampling Theory The Nyquist sampling theorem states that for a limited bandwidth (band- limited) signal with maximum frequency f MAX, the equally spaced sampling frequency f S must be greater than twice the maximum frequency f MAX, in order to have the signal be uniquely reconstructed without aliasing.
SIGLENT jitter on fast edges. 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. Bandwidth and Sample Rate An oscilloscope's bandwidth is typically described as the lowest frequency at which input signal sine waves are attenuated by 3 dB (- 30% amplitude error). At the oscilloscope bandwidth, sampling theory says the required sample r ate is fS = 2fBW.
SIGLENT However, digital signals have frequency components above the fundamental frequency (square waves are made up of sine waves at the fundamental frequency and an infinite number of odd harmonics), and typically, for 500 MHz bandwidths and below, oscilloscopes have a Gaussian frequency response. So, in practice, an oscilloscope's sample rate should be four or more times its bandwidth: fS = 4fBW. This way, there is less aliasing, and aliased frequency components have a greater amount of attenuation.
SIGLENT 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. The oscilloscope provides up to 28 Mpts memory depth. Press the Acquire button on the front panel; press the Mem Depth softkey and then turn the Universal Knob to select the desired value and push down the knob to confirm. Press the Mem Depth softkey continually can also select the desired value.
SIGLENT Sampling Mode The oscilloscope only supports real-time sample. In this mode, the oscilloscope samples and displays waveform within a trigger event. The maximum real-time sample rate is 2 GSa/s. Press the Run/Stop button 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.
SIGLENT Interpolation Method Under real-time sampling, the oscilloscope acquires the discrete sample values of the waveform being displayed. In general, a waveform of dots display type is very difficult to observe. In order to increase the visibility of the signal, the digital oscilloscope usually uses interpolation to “connect the dots” on the displayed waveform.
SIGLENT Figure 13 x Interpolation Figure 14 Sin(x)/x Interpolation SDS2000X-E User Manual 43
SIGLENT Acquisition Mode The acquisition mode is used to control how to generate waveform points from sample points. The oscilloscope provides the following acquisition mode: Normal, Peak Detect, Average and Eres. 1. Press the Acquire button on the front panel to enter the ACQUIRE function menu; 2. Press the Acquisition softkey; then turn the Universal Knob to select the desired acquisition mode and push down the knob to confirm. The default setup is Normal.
SIGLENT 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. Figure 16 Pulse With 0.01% Duty, Normal Mode Figure 17 Pulse With 0.
SIGLENT 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. The greater the number of averages is, the lower the noise will be and the higher the vertical resolution will be but the slower the response of the displayed waveform to the waveform changes will be. The available range of averages is from 4 to 1024 and the default is 16.
SIGLENT Figure 19 With Random Noise, Average Mode Eres This mode uses oversampling to average the neighboring points of the sample waveform to reduce the random noise on the input signal and generate much smoother waveforms on the screen. This is generally used when the sample rate of the digital converter is higher than the storage rate of the acquisition memory. Eres mode can be used on both single-shot and repetitive signals and it does not slow waveform update.
SIGLENT Horizontal Format Press the Acquire button on the front panel; then press the XY soft key to set the XY(On) or YT(Off) mode. The default setup is YT. YT Display channel Y input amplitude (typically voltage) vs. time. This is the normal viewing mode for the oscilloscope. In the Normal time mode, signal events occurring before the trigger are plotted to the left of the trigger point and signal events after the trigger plotted to the right of the trigger point.
SIGLENT X-Y 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.
SIGLENT Sequence Mode Sequence Mode provides faster data collection, but does not display waveforms during sampling process. It improves the waveform capture rate, delivering up-to 400,000 wfs/s. So it can capture the small probability events effectively. The oscilloscope runs and fills a memory segment for each trigger event and continues to trigger until memory is filled. After the memory buffer has been filled, it then displays the waveforms on the screen.
SIGLENT 2. Press the List softkey to turn on the list display. The list records the acquisition time of every frame and shows the frame number that displaying on the screen. 3. Press the Frame No. softkey; and then turn the Universal Knob to select the frame to display. 4. Press the 5. Press the softkey to replay the waveform from the current frame to 1. softkey to stop replay. 6. Press the frame.
SIGLENT Trigger The trigger mode is the most useful setting to help isolate signals of interest. When a waveform in the waveform stream meets the trigger condition, the oscilloscope captures this waveform as well as the neighboring part and displays them on the screen. For digital oscilloscopes, the waveforms will be displayed continuously no matter whether it is stably triggered, but only stable triggers can ensure a stable display.
SIGLENT Trigger Level Trigger Coupling Holdoff Noise Rejection Trigger Type Edge Trigger Slope Trigger Pulse Trigger Video Trigger Window Trigger Interval trigger Dropout Trigger Runt Trigger Pattern Trigger SDS2000X-E User Manual 53
SIGLENT Trigger Source The oscilloscope’s trigger source includes analog channels, EXT, EXT/5 and the AC Line. Press the Setup button on the front panel to enter the TRIGGER function menu; press the Source softkey and then turn the Universal Knob to select the desired trigger source. The current trigger source is displayed at the upper right corner of the screen. Select channel with signal input as trigger source to obtain stable trigger.
SIGLENT Trigger Mode The oscilloscope’s trigger mode includes auto, normal and single. The trigger mode affects the way in which the oscilloscope searches for the trigger. After the oscilloscope starts running, the oscilloscope operates by first filling the pre-trigger buffer. It starts searching for a trigger after the pre -trigger buffer is filled and continues to flow data through this buffer while it searches for the trigger.
SIGLENT Trigger Level Trigger level and slope define the trigger point, You can adjust the trigger level for a selected analog channel by turning the Trigger Level Knob. You can push the Trigger Level Knob to set the level to the waveform's 50% value immediately. If AC coupling is used, pushing the Trigger Level knob sets the trigger level to about 0 V.
SIGLENT Trigger Coupling Press the Setup button on the front panel to enter the TRIGGER function menu, and then press the Coupling softkey and turn the Universal Knob or press the Coupling softkey continually to select the desired coupling mode. The oscilloscope provides 4 kinds of trigger coupling modes: DC: Allow DC and AC components into the trigger path. AC: Block all the DC components and attenuate signals lower than 8 Hz.
SIGLENT Holdoff Trigger holdoff can be used to stably trigger complex waveforms (such as a series of pulses). Holdoff time is the amount of time that the oscilloscope waits before re -arming the trigger circuitry. The oscilloscope will not trigger until the holdoff time expires. Use the holdoff to trigger on repetitive waveforms that have multiple edges (or other events) between waveform repetitions.
SIGLENT Noise Rejection Noise Reject adds additional hysteresis to the trigger circuitry. By increasing the trigger hysteresis band, you reduce the possibility of triggering on noise. However, this also decreases the trigger sensitivity so that a slightly larger signal is r equired to trigger the oscilloscope. Press the Setup button on the front panel, and then press the Noise Reject softkey continually to set the option to On or Off to turn on or off the noise rejection function.
SIGLENT Figure 23 Noise Rejection enabled If the signal you are probing is noisy, you can set up the oscilloscope to reduce the noise in the trigger path and on the displayed waveform. First, stabilize the displayed waveform by removing the noise from the trigger path. Second, reduce the noise on the displayed waveform. 1. Connect a signal to the oscilloscope and obtain a stable display. 2.
SIGLENT Trigger Type The oscilloscope provides abundant advanced trigger functions, including various serial bus triggers.
SIGLENT Edge Trigger Edge trigger distinguishes the trigger points by seeking the specified edge (rising, falling, alter) and trigger level. 1. Press the Setup button on the front panel to enter the TRIGGER system function menu. 2. Press the Type softkey; turn the Universal Knob to select Edge and then push the knob to confirm. 3. Press the Source softkey; turn the Universal Knob to select the deserted trigger source. 4.
SIGLENT Slope Trigger The slope trigger looks for a rising or falling transition from one level to another level in greater than or less than a certain amount of time. In the oscilloscope, positive slope time is defined as the time difference between the two crossing points of trigger level line A and B with the positive edge as shown in the figure below. 1. Press the Setup button on the front panel to enter the TRIGGER function menu. 2.
SIGLENT Figure 25 Slope Trigger 6. Press the Limit Range softkey; then turn the Universal Knob to select the desired slope condition, and push down the knob to confirm. <= (less than a time value): Trigger when the positive or negative slope time of the input signal is lower than the specified time value. >= (greater than a time value): Trigger when the positive or negative slope time of the input signal is greater than the specified time value.
SIGLENT Pulse Trigger Trigger on the positive or negative pulse with a specified width. 1. Press the Setup button on the front panel to enter the TRIGGER function menu. 2. Press the Type softkey; turn the Universal Knob to select Pulse and then push the knob to confirm. 3. Press the Source softkey; turn the Universal Knob to select CH1 or CH2 as the trigger source. 4. Turn the Trigger Level Knob to adjust the trigger level to the desired place. 5.
SIGLENT [--,--] (within a range of time value):Trigger when the positive or negative pulse time of the input signal is greater than the specified lower limit of time and lower than the specified upper limit of the set time value. For example, for a positive pulse, if you set t (pulse real width) > 100 ns and t < 300 ns, the waveform will trigger.
SIGLENT Video Trigger Video triggering can be used to capture the complicated waveforms of most standard analog video signals. The trigger circuitry detects the vertical and horizontal interval of the waveform and produces triggers based on the video trigger settings you have selected. The oscilloscope supports standard video signal field or line of NTSC (National Television Standards Committee), PAL (Phase Alternating Line) HDTV (High Definition Television) and custom video signal triggers. 1.

SIGLENT Math Function Operation The oscilloscope supports differential (d/dt), integral (∫dt) and square root ( ) math functions. Differentiate d/dt (differentiate) calculates the discrete time derivative of the selected source. Where: d = differential waveform. y = channel 1, 2 data points. i = data point index. Δ t = point- to- point time difference. The dx option under d/dt math function operation menu shows the point- to- point time difference, and it ranges from 0.02div to 0.40div.
SIGLENT You can use differentiate to measure the instantaneous slope of a waveform. For example, the slew rate of an operational amplifier may be measured using the differentiate function. Note: Because differentiation is very sensitive to noise, it is helpful to set acquisition mode to Average. Integrate dt (integrate) calculates the integral of the selected source. You can use integrate to calculate the energy of a pulse in volt- seconds or measure the area under a waveform.
SIGLENT Figure 59 Integral with Offset Square Root Square root ( ) calculates the square root of the selected source. Where the transform is undefined for a particular input, holes (zero values) appear in the function output.
