Page 56: 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. 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...
Page 57: Sample Rate
Sample Rate The maximum sample rate of the T3DSO2000 is 2GSa/s. The actual sample rate of the oscilloscope is determined by the horizontal scale and acquisition depth. Turn the Horizontal Scale Knob to adjust the sample rate. The current sample rate is displayed in the information area at the upper-right corner of the screen.
Page 58: 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 59: To Specify Memory Depth
To Specify Memory Depth Memory depth refers to the number of waveform points that the oscilloscope can store in a single trigger acquisition and it reflects the storage ability of the sample memory. The T3DSO2000 provides up to 140 Mpts memory depth. Press the Acquire button on the front panel;...
Page 60: To Select Waveform Interpolation Method
To Select Waveform Interpolation Method Under real-time sampling, the oscilloscope acquires the discrete sample values of the waveform being displayed. In general, a waveform comprised of a singular dot per sample point 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 62: To Select Acquisition Mode
To Select Acquisition Mode The acquisition mode is used to control how to generate waveform points from sampled points. The T3DSO2000 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.
Page 63: 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 aliasing can be prevented but the noise displayed would be larger.
Page 64: Average
Average In this mode, the oscilloscope averages the waveforms from multiple acquisitions to reduce the random (uncorrelated) noise of the input signal and improve the vertical resolution. The greater the number of averages, the lower the noise will be and the higher the vertical resolution will be, but the slower will be the response of the displayed waveform to waveform changes.
Page 65: Eres (Enhanced Resolution)
Figure 18: With Random Noise, Average Mode Eres (Enhanced Resolution) This mode uses a digital filter to reduce the random noise on the input signal and generate much smoother waveforms on the screen. Eres can be used on both single-shot and repetitive signals and it does not slow down waveform update.
Page 66: To Change The Horizontal Format
To Change the Horizontal Format Press the Acquire button on the front panel; then press the XY softkey to set the XY (On) or YT (Off) mode. The default setup is YT. It is the normal / default viewing mode for the oscilloscope. It’s a signal (Y axis) amplitude verses time (T, X axis) display.
Page 67: Use Sequence Mode
Use Sequence Mode The Sequence Mode does not display the waveform during the sampling process. This improves the waveform capture rate by focusing the instrument resources on sampling. This increases the waveform capture rate to about 500,000 wfm/s. The Sequence Mode increases the ability to capture events with small probability effectively.

Page 69: To Trigger The Oscilloscope
Oscilloscope Triggering To observe and measure elements of an input waveform, it is most useful to have a stable and reproducible image of that waveform. To accomplish this, many oscilloscopes feature a trigger model that enables you to specify certain conditions for the input signal (only trigger on the rising edge, for example).
Page 70 The contents of this chapter: � Trigger Source � Trigger Mode � Trigger Level � Trigger Coupling � Trigger Holdoff � Noise Rejection � Trigger Type � Edge Trigger � Slope Trigger � Pulse Trigger � Video Trigger � Window Trigger �...
Page 71: Trigger Source
Trigger Source T3DSO2000 trigger sources include analog channels (CH1, CH2, CH3, CH4), as well as external trigger inputs EXT, EXT/5 and 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.
Page 72: Trigger Mode
Trigger Mode T3DSO2000 trigger modes include Auto, Normal and Single. The trigger mode affects the way in which the oscilloscope searches for the trigger. After the oscilloscope begins to capture data, 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 73: Trigger Level
Trigger Level Trigger level and slope define the trigger point, Positive Slope Negative Slope Trigger Level Trigger Point Trigger Point Input Signal The trigger level can be adjusted for a selected analog channel by turning the Trigger Level Knob. Push the Trigger Level Knob to set the level to the middle of the waveform. If AC coupling is used, pushing the Trigger Level knob sets the trigger level to approximately 0 V.
Page 74: 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. T3DSO2000 provides 4 trigger coupling modes: �...
Page 75: Trigger Holdoff
Trigger Holdoff Trigger holdoff can be used to stabilize the triggering of complex waveforms (such as a 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 76: 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 77 If the signal you are probing is noisy, you can setup 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 78: Trigger Type

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.
Page 83 �� [--,--](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 time value. For example, for a positive pulse, if you set t (pulse real width) >100ns and t<300ns, the waveform will trigger.
Page 84: 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 T3DSO2000 supports standard video signals for NTSC (National Television Standards Committee), PAL (Phase Alternating Line) HDTV (High Definition Television) and custom video signal triggers.
