Page 73: Overview
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 , the equally spaced sampling frequency f must be greater than twice the maximum frequency f , in order to have the signal...
Page 74: Bandwidth And Sample Rate
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).
Page 75 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: f = 4fBW.
Page 76: Memory Depth
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;...
Page 77: Interpolation Method
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”...

Page 79: Acquisition Mode
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. Press the Acquire button on the front panel to enter the ACQUIRE function menu;...
Page 80 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. Figure 16 Pulse With 0.01% Duty, Normal Mode Figure 17 Pulse With 0.01% Duty, Peak Detect Mode...
Page 81: Average
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.
Page 82: Eres
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.
Page 83: Horizontal Format
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. Display channel Y input amplitude (typically voltage) vs. time. This is the normal viewing mode for the oscilloscope.
Page 84 angle obtained should be within quadrant I and IV, namely within (0 to π/2) or (3π/2 to 2π). If the principal axis of the ellipse is within quadrant II and IV, the phase deviation angle obtained should be within quadrant II and III, namely within (π/2 to π) or (π...
Page 85: Sequence Mode
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.
Page 86 Figure 21 HISTORY Function Menu 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. Press the Frame No. softkey; and then turn the Universal Knob to select the frame to display.
Page 87: Trigger
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.

Page 89: Trigger Source
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.
Page 90: Trigger Mode
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.

Page 92: Trigger Level
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.
Page 93: Trigger Coupling
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.
Page 94: Holdoff
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.
Page 95: Noise Rejection
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 required to trigger the oscilloscope.
Page 96 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.

Page 244: Factory Setup
Factory Setup Oscilloscopes can be complicated devices, and having a way to return the instrument to a known state can be the fastest way to getting your instrument configured quickly. This is especially true when a single instrument has multiple users.
Page 245: Troubleshooting
The commonly encountered failures and their solutions are listed below. When you encounter those problems, please solve them following the corresponding steps. If the problem remains still, please contact SIGLENT as soon as possible. The screen is still dark (no display) after power on: Check whether the power is correctly connected.
Page 246 Make sure that the USB storage device being used is flash storage type. This oscilloscope does not support hardware storage type. Restart the instrument and then insert the USB storage device to check it. If the USB storage device still cannot be used normally, please contact SIGLENT.
