Chapter 6 Trigger System This chapter contains the detailed information of the trigger system of the oscilloscope. You are recommended to read this chapter carefully to understand the set functions and operation of the trigger system of the Smart series oscilloscope.
Page 98: Trigger And Trigger Adjustment
6.1 Trigger and Trigger Adjustment What is Trigger? The oscilloscope can capture a waveform only when it meets a preset condition first. This action of capturing the waveform according to the condition is Trigger. The so-called capture waveform is that the oscilloscope grabs a signal and displays it.
Page 99 Chapter 6 Trigger System The oscilloscope can stably display a periodic signal. Figure 6-1 Stably Displayed Periodic Signal Figure 6-2 Non-Stably Displayed Periodic Signal...
Page 100 Grab the segment you want to observe from a fast and complex signal Figure 6-3 Abnormal Signal in Periodic Signals Figure 6-4 Abnormal Signal Captured by Setting Trigger Level...
Page 101 Chapter 6 Trigger System What is Forced Trigger? When the oscilloscope does not meet the trigger condition, the artificial or automatic oscilloscope trigger is the forced trigger. It means that the oscilloscope only grabs a signal segment for display regardless of whether the condition is met or not.
Page 102 Figure 6-5 Oscilloscope Trigger Mode Setting If a signal feature is not understood, the oscilloscope should be set as “Auto” mode, which can ensure that the oscilloscope can also display the waveform when other trigger settings are not correct. Although the waveform is not necessarily stable, it can provide the intuitive judgment for our further adjustment of the oscilloscope.
Page 103 Chapter 6 Trigger System When we set a specific trigger condition for a specific signal, especially when the time interval for satisfying the trigger condition is long, we need to set the trigger mode to “Normal” so as to prevent the oscilloscope from automatic forced trigger.

When there is low frequency noise in the waveform, stable edge triggering can be obtained using LF rejection coupling. NoiseRej. (Noise Rejection Coupling) - Noise rejection can add extra hysteresis to the trigger circuit. By increasing the trigger hysteresis band, the possibility of noise triggering can be reduced. But it also reduces the trigger sensitivity, so triggering the oscilloscope requires a slightly larger signal.

11.1 Sampling Overview To understand the sampling and sampling modes of the oscilloscope, you need to understand the sampling principle, aliasing, oscilloscope bandwidth and sampling rate, oscilloscope rise time, required oscilloscope bandwidth, and the influence of memory depth on the sampling rate. Sampling principle According to the Nyquist sampling principle, for a bandwidth-limited signal with the maximum frequency f , the...
Page 207 Chapter 11 Sampling System Figure 11-1 Aliasing Oscilloscope bandwidth and sampling rate The oscilloscope bandwidth usually refers to the lowest frequency at which the input signal sine wave is attenuated by 3dB (-30% amplitude error). For oscilloscope bandwidth, according to the sampling principle, the required sampling rate is f .
Page 208 Frequency Figure 11-2 Theoretical Brick-Wall Frequency Response However, digital signals have frequency components that exceed the fundamental frequency (the square wave consists of sine waves at fundamental frequency and an infinite number of odd harmonics), and for bandwidths of 500MHz and below, the oscilloscope typically has Gaussian frequency response.
Page 209 Chapter 11 Sampling System Aliasing Frequency Figure 11-3 Sampling Rate and Oscilloscope Bandwidth The oscilloscope bandwidth is limited to 1/4 sampling frequency and reduces the frequency response above the Nyquist frequency. ≥4f Therefore, in fact, the oscilloscope sampling rate should be 4 times or more of its bandwidth: f .
Page 210 Oscilloscope rise time The oscilloscope rise time is closely related to its bandwidth. The rise time of an oscilloscope with Gaussian type frequency response is approximately 0.35/f (based on the standard from 10% to 90%). The oscilloscope rise time is not the fastest edge speed that an oscilloscope can accurately measure. It is the fastest edge speed that the oscilloscope can produce.
Page 211 Chapter 11 Sampling System According to Dr. Howard W. Johnson’s book “High-Speed Digital Design–A Handbook of Black Magic”, all fast edges have wirelessly continuous frequency components. However, there is a turning point (or “inflection point”) in the fast edge spectrum at which frequency components above f are negligible in determining the knee signal shape.

Page 214 This mode produces the best display effects for most waveforms. Peak sampling mode In peak sampling mode, when the horizontal time base setting is low, the minimum and maximum sample values are retained to capture rare events and narrow events (with any noise expanded). This mode will display all pulses that are at least as wide as the sampling period.

Page 217 Chapter 11 Sampling System The average number can be set in the selection box after the average sampling mode, and can be set to eight order of magnitudes: 2, 4, 8, 16, 32, 64, 128 and 256. The higher the average number is, the slower the response of the displayed waveform-to-waveform changes. A compromise must be made between the response speed of waveform versus the changes and the degree of noise reduction shown on the signal.
Page 218 Figure 11-7 Waveform after choosing the average sampling mode, with average number 32 Envelope sampling mode In the envelope sampling mode, the superposition effect of several sampled waveforms can be observed. The maximum and minimum values of one signal can be captured in the specified N sample data, and the number of waveform superpositions can be set to 2, 4 , 8, 16, 32, 64, 128, 256 or ∞.
Page 219: Record Length And Sampling Rate
Chapter 11 Sampling System Figure 11-8 AM Signal in Envelope Sampling Mode (32) 11.4 Record Length and Sampling Rate The record length is the data volume for each captured waveform. For example, if the record length is 700K, it means that 700K sample points are captured by one trigger.
Page 220 In the main menu, tap to enter the record length setting menu, which can be set by tapping the corresponding record length. Figure 11-9 Record Length In normal refresh mode, if it is a single channel, the record length can be set to 14k, 140k, 1.4M, 14M, 28M, Auto; if it is dual channel, the record length can be set to 7k, 70k, 0.7M, 7M, 14M, Auto;...
Page 221 Or, if the memory depth is 140K (fixed value), the sampling rate is 1GSa/s, and the horizontal time base is 1us, the acquisition time is 140us, which is 10 times of the current display time on the entire screen. For a single channel in a channel pair, the maximum sampling rate of the Smart Series oscilloscope is 1GSa/s.
Page 222 If any two channels are opened, the sampling rate of the two channels will halved. For example, when CH1 and CH3 are opened, the sampling rates of CH1 and CH3 are both 500 MSa/s. If any three channels or all four channels are opened, the sampling rate per channel will become 1/4 of the maximum sampling rate.
