X: Linear interpolation, the simplest way of interpolation, connects two original points • with a straight line. Sinc: Sin(x)/x interpolation, the original point is interpolated according to the • Nyquist reconstruction formula, which has a good time-domain recovery effect for sine wave. But for step signals/fast rise times, it will introduce false overshoot due to the Gibbs phenomenon. -
Page 48: Roll Mode
Peak mode Normal mode 14.2.3 Roll Mode Press the Roll button on the front panel to enter roll mode. In this mode, the waveform moves across the screen from right to left, similar to a strip chart recorder. The horizontal delay control of the waveform will be disabled when roll mode is active. It only operates at timebase values of 50 ms/div and above. - Page 49 The T3DSO2000A can achieve a minimum 2μs trigger interval in Sequence mode, corresponding to a waveform update rate of 500,000 wfm/s. After the acquisition is finished, the oscilloscope will map all the segments together to the screen. If you need to view and analyze each frame separately, history mode will help (see the section "...
- Page 50 In normal mode, 5 pulses can be obtained on the screen with the sample rate of 1 GSa/s at the maximum memory depth. Set the trigger mode to "Single", the timebase to 50 ns/div. Turn on the Sequence mode, and set the segments to maximum (5,000 in this example, up to 90,000 depending on the number of samples at the current time base).

Page 51: History
In the example, 5000 pulses can be obtained with the sample rate of 2 GSa/s at the maximum memory depth. 14.3 History Press the History button on the front panel or touch Analysis>History to recall history dialog box. A. Turn on or off history mode B. - Page 52 The oscilloscope automatically stores acquired frames. It can stores up to 90,000 frames but the number varies due to the channel memory depth and timebase settings. Turn on history mode, then the stored frames can be recalled and measured. Continuing with the example in the section above. In Sequence mode, all waveforms that satisfy the trigger conditions are mapped to the display.

Page 55: Trigger
15 Trigger 15.1 Overview The oscilloscope only acquires waveforms of interest (i.e. the ones that satisfy the trigger condition) and aligns all trigger events at the trigger position to form a stable waveform display. The trigger is one of the most important features of an oscilloscope since we can only analyze a signal that we are able to trigger in a reliable and stable manner. - Page 56 A. Touch the level region and rotate the Level knob on the front panel to adjust trigger level; touch the region again and the virtual keypad will be available B. ▲ to increase and ▼ to decrease the trigger level C.

The oscilloscope judges whether a waveform satisfies the trigger condition when it crosses the trigger level, shown in the example as a yellow dashed horizontal line. -
Page 58: Trigger Mode
15.4 Trigger Mode The trigger mode determines how the oscilloscope acquires waveforms. ：An internal timer triggers the sweep after a preset timeout period if no trigger has Auto been found, so that the oscilloscope continuously updates the display whether a trigger happens or not. -
Page 59: Edge Trigger
Window--Trigger when the signal leaves the widow region. Interval--Trigger on the second edge when the time between the edges is inside or outside a selected time range Dropout--Trigger when the signal disappears for longer than the Dropout value. Runt--Trigger when a pulse crosses the 1st threshold but not the 2nd before re-crossing the 1 threshold again Pattern-- Trigger when pattern condition transitions from false to true. -
Page 60: Slope Trigger
15.5.3 Slope Trigger The slope trigger looks for a rising or falling transition from one level to another level in the specified time range. For example, positive slope time is defined as the time difference between the two crossing points of trigger level lines A and B with the positive edge as shown in the figure below. -
Page 61: Pulse Trigger
Great than a time value（≥）-- Trigger when the positive or negative slope time of the input signal is greater than the specified time value. Within a range of time value（[--,--]）-- Trigger when the positive or negative slope time of the input signal is greater than the specified lower limit of time and lower than the specified upper limit of time value. -

Holdoff, coupling, and noise reject can be set in the dropout trigger, see the sections "Holdoff", "... - Page 70 Logic (AND, OR, NAND, NOR), source, limit range, and time value can be set in the trigger dialog box.

Page 71: Trigger Source
15.6 Trigger Source The trigger sources supported by each trigger type are different. See the table below for details: 15.7 Holdoff Holdoff is an additional condition for triggers and can be used to stabilize the triggering of complex waveforms (such as a pulse series). It can be set to a time or number of events. -
Page 72: Trigger Coupling
For example, to achieve a stable trigger on the repetitive pulses shown in the figure below set the holdoff time (t) to 200 ns < t < 600 ns. Holdoff by Event The holdoff event is the number of events that the oscilloscope counts before re-arming the trigger circuitry. -
Page 73: Noise Reject
• HFR: Signals are DC coupled to the trigger circuit and a low-pass filter network attenuates high frequencies (used for triggering on low frequencies). See the datasheet for details of the cut-off frequency. • LFR: The signal is coupled through a capacitive high-pass filter network, DC is rejected and low frequencies are attenuated. -
Page 74: Zone Trigger
Noise Reject On 15.10 Zone Trigger The T3DSO2000A includes a zone trigger to help isolate elusive glitches. There are two user-defined areas: Zone1 and Zone2. Users can set the property of each zone as “intersect” or “not intersect” as an additional condition to further isolate the interesting event quickly. - Page 75 Gesture When the zone trigger is turned on, touch-and-hold on any position within the waveform area and draw a rectangular box, as shown in the following figure: When the users finger moves off the screen, a menu pops up for selecting the zone and setting the zone properties.
