3.1 z Explore Waveform Zoom
Large data storage can realize long-time waveform capture while maintaining a high
sampling rate and the waveform is guaranteed not to be distorted. However, our
purpose is not only to obtain waveforms without any distortion, but also use an
oscilloscope to automatically and conveniently analyze the abnormality in waveforms,
enabling users to locate abnormal signals within millions of waveforms without any
effort.
Figure 3-1: zExplore Panel
3.1.1 Waveform Zoom
The waveform zoom function can display not only the whole waveform but also the
details of a waveform. ZDS2000B series oscilloscope can use high-speed parallel
processing capability of powerful multi-chip FPGA array to realize the zoom mode in
the case of real-time massive data response.
Press “Waveform Zoom”button to enter the waveform zoom interface, as shown in
Figure 3-2.

The display screen is divided into two parts. The upper half part is the normal display
view, also called main time base; and the lower half part is the zoom display view,
also called secondary time base, which is a magnified display of the specified area of
a waveform in the normal display view.
(1) Horizontal time-base adjustment of a waveform in the zoom mode
The waveform selected in the “blue”box is adjusted after entering the zoom mode. If
the normal view mode is selected, users can expand or compress the waveform in
the horizontal direction; if the zoom view mode is selected, users can adjust the size
of zoom window to view the waveform details.
Figure 3-3: Horizontal control area
(2) Waveform translation in the zoom mode
The large knob and time base offset knob are used to adjust the offset of main time
base waveform or secondary time base zoom window so that user can observe the
waveforms at different positions, as shown in Figure 3-4.
Figure 3-4: Waveform/zoom window translation
The large knob is used to quickly move main time base waveforms and secondary
time base zoom windows. The wider the range of the large knob is turned, the faster
the zoom window moves. The horizontal offset knob is used to slowly move main time
base waveforms and secondary time base zoom windows.
(3) Waveform play/pause
When the memory depth is large, much waveform data can be recorded, but the
whole waveform signal may not be observed completely. However, user can press

the “Waveform play/pause”button of ZDS2000B series oscilloscope to automatically
play and move the secondary time base waveform in the zoom mode, as shown
inFigure 3-5.
Turn the “large knob”to adjust the play speed of waveform. Faster and wider
range the large knob is turned, faster the waveform is played. The speed can
reach its maximum value.
Reversely turn the “large knob”to change the play direction of waveform. When
the zoom window moves to the left, the waveform passes through the window
from left to right, and users will observe the waveform moves to the right in the
secondary time base; on the contrary, the waveform moves to the left.
Press the navigation but ton with the same direction as the secondary time base
waveform play to increase the waveform play speed. The more times the button
is pressed, the faster the waveform is played. Press the backward navigation
button to decrease the waveform play speed. The more times the button is
pressed, the slower the waveform is played. When the speed is reduced to 0, the
waveform will be played in the opposite direction.
Press the “Waveform play/pause”button again to stop the movement of
waveform temporarily.
Figure 3-5: Waveform play/pause
3.1.2 Search and marking
The “search”function can quickly find the interested waveform signals and then mark
them automatically for user to view these signals later conveniently. It provides many
search conditions, including edge, pulse width, rising/falling time, cycle, frequency,
duty cycle, runt, etc.
The “marking”function divides into manual marking and automatic marking. It can
mark the position of interested waveform in the sampled waveforms and quickly
locate the abnormal signal.

When using the manual marking function, users can press [Mark/Clear] button at the
position of the interested waveform to mark it, and then press this button again to
delete the marking. Press the left or right navigation button to jump from one marking
position to the other.
3.2 Segmented storage funciton
The segmented storage is triggered several times in the process of acquisition, and
the sampled data for each trigger are stored in the individual segment of storage
space.
There is no waveform appearing in the signal for a long time, and then the waveform
appears along with interference, as shown in Figure 3-7. In order to facilitate analysis
and save storage space, the segmented storage is used to record each section of
waveform under triggering conditions. After the waveform is captured, users can use
the left and right navigation buttons to perform abnormality analysis and processing
for each section of waveform.
Figure 3-7: Segmented storage application
The total memory depth is divided into n segments, as shown in Figure 3-8. The first
segment is used for display, and the second segment begins to be used for storage,
that is, the sampled data is stored in the second segment when the first triggering
occurs; after the second segment is full, the first triggering ends and users should
wait for the arrival of the second triggering; and then the sampled data is stored into
the third segment when the second triggering occurs; and so on.

3.3 Waveform search
ZDS2000B series oscilloscope has powerful real-time hardware search function. It
provides many waveform search modes, including edge, pulse width, cycle,
frequency, rising/falling time, duty cycle and runt, and sets the measuring modes in
detail, such as greater than, less than, within the range and outside the range.
ZDS2000B is also able to quickly locate the interested signal, greatly improving the

Users can use the cursor measurement function to measure the X axis values (such
as time) and Y axis values (such as voltage) of selected waveforms. There are two
pairs of measurement cursors: X-type cursor or Y-type cursor. The X-type cursor is
generally used to measure time parameters and Y-type cursor is generally used to
measure voltage parameters, as shown in Figure 3-11.
