Page 38: Enabling The Channel
Enabling the Channel The oscilloscope includes 2 analog input channels, and each channel shares the same vertical control system. Since the vertical system setting methods of each channel are the same, this chapter uses CH1 as an example to show how to control the vertical settings. Connect the signal to the CH1 channel connector, and then press CH1 in the vertical control area (VERTICAL) on the front panel to enable CH1.
Page 39: Adjusting The Scale
Adjusting the 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 step namely 2 mV/div, 5 mV/div, 10 mV/div …10 V/div.

Page 50: Overview
Overview To understand the oscilloscope's sampling and acquisition modes, it is helpful to understand sampling theory, sample rate, and oscilloscope bandwidth. 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 uniquely reconstruct the signal without aliasing.
Page 51: Bandwidth And Sample Rate
Waveform Leakage: when the sample rate is too low, the waveform reconstructed from the sample data cannot reflect all the actual signal information. Pulse disappeared Bandwidth and Sample Rate An oscilloscope's bandwidth is typically described as the lowest frequency at which the input sinusoidal signal is attenuated by 3 dB, i.e., the scope’s reading of a frequency equal to its bandwidth is 30% lower than the true signal strength.
Page 52 In fact, digital signals have frequency components above the fundamental frequency (ex., a square wave is composed of a sine wave of the fundamental frequency and numerous odd harmonics), and generally, for oscilloscopes with a bandwidth of 500 MHz and below, the system has a Gaussian frequency response.
Page 53: Memory Depth
Memory Depth Memory depth refers to the number of waveform points that the oscilloscope can store in a single trigger sample, and reflects the storage capacity of the sample memory. Press Acquire on the front panel; press the Mem Depth F key and then turn the Universal Knob to select the desired value and push down the knob to confirm.
Page 54: Sampling Mode
Sampling Mode This oscilloscope only supports real-time sampling. In this mode, the oscilloscope samples and displays waveform around a trigger event. The maximum real-time sample rate is 1GSa/s. Press Run/Stop to pause the sample, and the oscilloscope will hold the last display. At this point, you can still use the vertical control and horizontal control to pan and zoom.
Page 55: Interpolation Method
Interpolation Method Under real-time sampling, the oscilloscope acquires discrete sampled values of the waveform being displayed. In general, a waveform of discrete dots is difficult to interpret. In order to increase the clarity of the signal, digital oscilloscopes usually use interpolation to display a continuous waveform rather than disconnected sample points.
Page 56 Figure 16 x Interpolation Figure 17 Sinx/x Interpolation...
Page 57: Acquisition Mode
Acquisition Mode The acquisition mode is used to control how waveform points are generated from sample points. The oscilloscope provides the following acquisition modes: Normal, Peak Detect, Average, and ERES. Press Acquire on the front panel to enter the ACQUIRE function menu; Press the Acquisition F key;...
Page 58: Peak Detect
Peak Detect In this mode, the oscilloscope acquires the maximum and minimum values of the signal within the sample interval to get the signal's “envelope” or the narrow pulse of the signal that might be lost. In this mode, signal confusion can be prevented but more noise will be displayed. In this mode, the oscilloscope can display all pulses with pulsewidths at least as wide as the sample period.
Page 59: Average
Figure 20 Pulse With 0.1% Duty, Peak Detect Mode 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 and the higher the vertical resolution will be.
Page 60 Figure 21 With Random Noise, Normal Mode Figure 22 With Random Noise, Average Mode...
Page 61: Eres
ERES This mode uses a kind of ultra-sample technique to average the neighboring points of the sample waveform to reduce random noise in the input signal and generate much smoother waveforms on the screen. ERES mode is generally used when the sample rate of the digital converter is higher than the storage rate of the acquisition memory.
Page 62: Horizontal Format
Horizontal Format Press Acquire on the front panel; then press the XY F key to choose XY (On) or YT (Off ) mode. The default setup is YT. This is the normal viewing mode. In this 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.
Page 63: Sequence Mode
Sequence Mode Sequence is an acquisition mode that does not display the waveform during the sampling process. This improves the waveform capture rate, and the maximal capture rate is 400,000 wfs/s. Because of the high capture rate, sequence mode can capture small probability events effectively. The oscilloscope runs and fills a memory segment for each trigger event.
Page 64 Press the Frame No. F key; and then turn the Universal Knob to select the frame to display. Press the F key to replay the waveform from the current frame to 1. Press the F key to stop replay. Press the F key to replay the waveform from the current frame to the last frame.
Page 65: Trigger
Trigger The oscilloscope can be set to trigger according to your requirements. When a waveform in the signal meets the trigger condition, the oscilloscope captures this waveform and the neighboring part and displays them on the screen. The oscilloscope displays a waveform whether or not it is stably triggered, but only a stable trigger can ensure a stable display.
Page 66 Contents: u Trigger Source u Trigger Mode u Trigger Level u Trigger Coupling u Trigger Holdoff u Noise Rejection u Trigger Type...
Page 67: Trigger Source
Trigger Source Press Trigger Setup on the front panel to enter the TRIGGER function menu; press the Source F key and then turn the Universal Knob to select the desired trigger source. The current trigger source is displayed at the bottom of the screen. Select the channel with signal input as the trigger source to obtain stable trigger.
Page 68: Trigger Mode
Trigger Mode The oscilloscope’s trigger mode includes auto, normal, single and Force. The mode affects how the oscilloscope searches for the trigger event. After the oscilloscope starts running, it first fills the pre-trigger buffer. After the pre-trigger buffer is filled, it begins to search for a trigger. Data continues to flow through this buffer while the scope searches for the trigger.
Page 69: Trigger Level
Trigger Level The trigger level and slope define the trigger point, You can adjust the trigger level for a selected analog channel by pressing Trigger Level and turning the Universal Knob. You can push the Universal Knob to set the level to the waveform's 50% value immediately. If AC coupling is used, pushing the Universal Knob sets the trigger level to about 0 V.
Page 70: Trigger Coupling
Trigger Coupling Press Trigger Setup on the front panel to enter the TRIGGER function menu. Then, press the Coupling F key and turn the Universal Knob or press the Coupling F key repeatedly 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 71: Trigger Holdoff
Trigger Holdoff Trigger holdoff can be used to stably trigger complex waveforms (such as pulse series). The 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 repetitive waveforms with multiple edges (or other events) between waveform repetitions.
Page 72: 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. Press Trigger Setup on the front panel, and then press the Noise Reject F key repeatedly to set the option to On or Off to turn on or off the noise rejection function.
Page 73 Figure 26 Turn on the Noise Reject 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.
Page 74: Trigger Types

Page 75: Edge Trigger
Edge Trigger Edge triggering distinguishes the trigger points by seeking the specified edge (rising, falling, alternating) and trigger level. Press Trigger Setup on the front panel to enter the TRIGGER system function menu. Press the Type F key; turn the Universal Knob to set select Edge and then push the knob to confirm.
Page 76: Slope Trigger
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.
Page 77 Figure 28 Slope Trigger Press the Limit Range F key; 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 input signal's positive or negative slope time is lower than the specified time value.
Page 78: Pulse Trigger
Pulse Trigger Trigger on the positive or negative pulse with a specified width. Press Trigger Setup on the front panel to enter the TRIGGER function menu. Press the Type F key; turn the Universal Knob to select Pulse and then push the knob to confirm. Press the Source F key;...
Page 79 --][-- (outside a range of time value): trigger when the input signal's positive or negative pulse time is greater than the specified upper limit of time and lower than the specified lower limit of time. Figure 29 Pulse Trigger Coupling and noise rejection can be set in pulse trigger mode. See the sections "Trigger Coupling" and "Noise Rejection"...
Page 80: Video Trigger
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 trigger.

Page 82 Figure 30 Video Trigger To Use Custom Video Trigger Custom video trigger supports frame rate of 25Hz, 30Hz, 50Hz and 60Hz, and the line range is available from 300 to 2000. The steps below show how to set custom trigger. Press Trigger Setup on the front panel to enter the TRIGGER function menu.
Page 83: Window Trigger
Window Trigger The window trigger mode has a high trigger level and a low trigger level. The instrument triggers when the input signal passes through either trigger level. There are two kinds of window types: Absolute and Relative. They have different trigger level adjustment methods.
Page 84 Figure 31 Absolute Window Trigger To set relative window triggers: Press Trigger Setup on the front panel to enter the TRIGGER system function menu. Press the Type F key; then use the Universal Knob to select Window and push down the knob to confirm.
Page 85 Figure 32 Relative Window Trigger Coupling and noise rejection can be set in Window trigger mode. See the sections "Trigger Coupling" and "Noise Rejection" for details.
Page 86: Interval Trigger
Interval Trigger Trigger when the time difference between neighboring rising/falling edges meets the specified criteria (<=, >=, [--,--], --][--). To set an interval trigger: Press Trigger Setup on the front panel to enter the TRIGGER system function menu. Press the Type F key; then use the Universal Knob to select Interval and push down the knob to confirm.
Page 87 Figure 33 Interval Trigger Coupling and noise rejection can be set in interval trigger mode. See the sections "Trigger Coupling" and "Noise Rejection" for details.
Page 88: Dropout Trigger
Dropout Trigger Dropout trigger mode has two types: Edge and State. Edge Trigger when the time interval △T - from when the rising edge (or falling edge) of the input signal passes through the trigger level to when the next rising or falling edge passes through the trigger level - is greater than the timeout time set, as shown in the figure below.
Page 89 Figure 34 Edge Dropout Trigger To set state Dropout trigger: Press Trigger Setup to enter the TRIGGER system function menu. Press the Type F key; then turn the Universal Knob to select Dropout and push down the knob to confirm. Press the Source F key;...
Page 90 Figure 35 State Dropout Trigger Coupling and noise reject can also be set in dropout trigger mode. See the sections "Trigger Coupling" and "Noise Rejection" for details.
Page 91: Runt Trigger
Runt Trigger Runt trigger mode has two trigger levels, high and low. It looks for pulses that cross one threshold but not the other, as shown below. A positive runt pulse across through a lower threshold but not an upper threshold. A negative runt pulse across through an upper threshold but not a lower threshold.
Page 92 Figure 36 Runt Trigger Coupling and noise rejection can be set in runt trigger mode. See the sections "Trigger Coupling" and "Noise Rejection" for details.
Page 93: Pattern Trigger
Pattern Trigger Pattern trigger mode identifies a trigger condition by looking for a specified pattern. The pattern trigger can be expanded to incorporate delays, similar to other triggers. Pattern durations are evaluated using a timer. The timer starts on the last edge that makes the pattern “true”. Potential triggers occur on the first edge that makes the pattern false, provided that the time qualifier criterion has been met.
Page 94 Press the Holdoff Close F key to turn on the Holdoff function; then turn the Universal Knob to select the desired value. Figure 37 Pattern Trigger Holdoff mode can be set using patterns. See the section "Trigger Holdoff" for details.
