Page 51: Overview Of Sampling
Overview of Sampling To understand the oscilloscope's sampling and acquisition modes, it is helpful to understand sampling theory, sample rate and 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...
Page 52: Sample Rate
Sample Rate The maximum sample rate of the oscilloscope is 2GSa/s. The actual sample rate of the oscilloscope is determined by the horizontal scale. Turn the Horizontal Scale Knob to adjust the sample rate. The actual sample rate is displayed in the information area at the upper- right corner of the screen.
Page 53: Oscilloscope Bandwidth And Sample Rate
Oscilloscope 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 rate is f = 2f However, the theory assumes there are no frequency components above f in this...
Page 54: Select Memory Depth
Select 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 14 Mpts memory depth. Press the Acquire button on the front panel;...
Page 55: Select Sampling Mode
Select 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 1GSa/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.
Page 56: Select Waveform Interpolation Method
Select Waveform 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 the interpolation method to display a waveform.
Page 58: Select Acquisition Mode
Select 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 High Resolution. 1. Press the Acquire button on the front panel to enter the ACQUIRE function menu; 2.
Page 59: 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 envelope of the signal or the narrow pulse of the signal that might be lost. In this mode, signal confusion can be prevented but the noise displayed would be larger.
Page 60: 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 The available range of averages is from 4 to 1024 and the default is 16.
Page 61: High Resolution
Figure 18 With Random Noise, Average Mode High Resolution This mode uses a kind of ultra-sample technique 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 62: Change The Horizontal Format
Change the 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. It 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.
Page 63: Use Sequence Mode
Use Sequence Mode Sequence is also a kind of acquisition mode, which does not display waveform during sampling process. It improves the waveform capture rate, and the maximal capture rate is more than 300,000 wfs/s. So it can capture the small probability event effectively. The oscilloscope runs and fills a memory segment for each trigger event.
Page 64 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.
Page 65: To Trigger The Oscilloscope
To Trigger the Oscilloscope For trigger, you set certain trigger condition according to the requirement and when a waveform in the waveform stream meets this condition, the oscilloscope captures this waveform as well as the neighboring part and displays them on the screen. For digital oscilloscope, it displays waveform continuously no matter whether it is stably triggered, but only stable trigger can ensures stable display.

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.
Page 68: Trigger Mode
Trigger Mode The oscilloscope’s trigger mode includes auto, normal and single. 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 69: Trigger Level
Trigger Level Trigger level and slope define the trigger point, Positive Slope Negative Slope Trigger Level Trigger Point Trigger Point Input Signal You can adjust the trigger level for a selected analog channel by turning the Trigger Level Knob.

Page 70: 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: ...
Page 71: Trigger Holdoff
Trigger Holdoff Trigger holdoff can be used to stably trigger the complex waveforms (such as pulse series). 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.
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.
Page 73 Figure 22 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. Second, reduce the noise on the displayed waveform.
