General knowledge of users’ interface
2.8 General knowledge of users’ interface
This section does a simple introduction and description to oscilloscope users’ interface.
After reading this section, you can familiar with the oscilloscope display interface in a short
time. For the specific settings and adjustments, users can refer Chapter Three. The screen
items shown in the following picture may not appear on the same screen simultaneously, the
users’ interface is shown in figure 2-8.

General knowledge of users’ interface
Picture 2-8 users’ interface
25
General knowledge of users’ interface
Users’ interface:
1. There are five kinds of wave capturing mode indicator
Auto: in auto mode, according the input signal to automatically adjust the vertical scale, the
horizontal time scale, and the trigger mode to make the waveform displays as the best.
Run: sampling waveform data
Stop: stop sampling waveform data
Waiting trigger: a transient state just before trigger event occur
Rolling: sampling waveform data when scroll the touch screen
2. The probe calibration related square wave output indicator
3. The trigger position icon indicates the waveform trigger position
4. The cursor can be divided into vertical cursor and horizontal cursor, used for measuring
cursor
5. The extension position icon, the center point of the time base zooming out
6. Waveform position indicator, indicate the position of waveform on current screen between
the total sampling data.
7. Memory Depth, the display value 120K at the right side, which means the current channel
memory depth.
8. Refresh rate, actual wfrms/s at the left side

Understand touch screen
2. Five operating areas on the touch screen
Frames of the waveform display divide the touch screen into five areas, only the function
menu turned off, can operate these areas. See figure 2-10.
Touchable area description:
1. Horizontal drag area: From the upper waveform window to screen, top. You can move
waveform horizontally in this area.
2. Vertical drag and the current channel selection area: where the waveform displays from
the left frame to the right frame. Press the channel icon switch to the current channel,
vertical drag only applies to the current channel.
3. Current channel switch area: press the frame corner at Ch1, Ch2, Math, or Ref and users
can switch one of them to the current channel.
4. Waveform zoom area: the whole waveform display area can be used as waveform zoom
in/out area.
5. Trigger level and drag the cursor area: the area between waveform window's right edge
and screen’s right edge where users can move the trigger level or drag the cursor.

Probe compensation
2.11 Probe compensation
Before connecting to any channels, users should make a probe compensation to insure
the probe match to the input channel. The probe without compensation will lead to larger
errors or mistakes, and probe compensation optimizes the signal path and makes the
measurement more precise. If the temperature is 10 degree or above, this progress must be
done to insure the accuracy of the measurement. See picture2-12
Picture 2-12 probe compensation menu
Procedures of probe compensation as follow
1) Connect the oscilloscope probe to Ch1. If you are using a hook head, users should
ensure the good connection with the probe.

Channel selection
3.1 Channel selection
Current channel: oscilloscope can display multiple waveforms simultaneously, but there is
only one waveform can display on the top, which is called the current channel. The current
channel arrow is solid, otherwise the arrow is hollow, and the differences are shown in figure
3-1.

2. Average: waveform does average processing from multiple sampling. You can use the
average functions to reject random or uncorrelated noise in the waveform without loss of
bandwidth. Press or roll the wheel to set the waveform average number, selectable
average number is 2, 4, 8, 16, 32, 64, 128, 256, and the waveform is shown in figure 3-6.

Bandwidth selection
3.4 Bandwidth selection
Press and to set the required bandwidth limit , the 20MHz bandwidth can
only keep low frequency component under 20MHz, and high frequency component above
20MHz can attenuation effectively. The difference between full bandwidth and 20MHz can
be expressed by waveform. Full bandwidth is shown in picture 3-9; 20MHz bandwidth is
shown in picture 3-10.
Picture 3-9 Full Bandwidth picture 3-10 20 MHz Bandwidth
In picture 3-10, the arrow point indicates bandwidth(20MHz).
Use delay
51
3.5 Use delay
You can begin to capture the waveform for some time after the trigger point has been
detected. When delay is on, the trigger can be removed from the screen, and the horizontal
extension point locates in the middle of the screen, and adjusts the horizontal time scale can
observe more details of the waveform.
Sometimes the measured value is not stable while measuring pulse width. This is called
pulse width jitter. In this case, turn on delay function and extend the time base; and delay
sampling after rising trigger to observe the falling waveform jitter. For example,
1) Press then then to choose delay on
2) Move the waveform to the left, making the falling edge of waveform in the middle of
the screen, as shown in figure 3-11,

Note: when the delay on, adjust the time scale, and zoom the waveform on the center point of
the screen. When Delay off, adjust the time scale, and zoom the waveform on the trigger
position
3.6 Set channel polarity
The waveform polarity is relative to the zero level (ground), if the actual signal is positive
however in the instrument is negative, which called negative polarity or phase invert. By
setting the Ch1 and Ch2 channel’s polarity users can make the two channels work
respectively in a phase invert or normal state. Follow the examples to set channel polarity.
Ch1 and Ch2 connect to the same rectangular pulse signal simultaneously and make the

3.7 Set channel attenuation ratio
To coincide with actual use probe attenuation radio, it is necessary to adjust channel
attenuation factor under the channel menu. Such as probe attenuation radio of 1:1,
corresponding to the input channel attenuation factor set as 1 x.
When probe attenuation factor is changed, users need to enter this menu to set the
corresponding attenuation factor, only the set matches, can display waveform’s amplitude
rightly. Probe attenuation radios and attenuation factors are shown in the table below,
Press then then and to open channel attenuation factor

Capture single pulse signal
5.2 Capture single pulse signal
Capturing the pulse, burr and non-periodic signal are the advantage of digital oscilloscope.
If you capture a single signal, require some knowledge of signal and then you can correctly
set trigger level and trigger. For instance, pulse is a TTL level logic signal, trigger level
should be set to 2v, and the trigger mode is set as rising trigger. If you are not sure about the
signal, you can identify the trigger level and trigger through the automatic mode.
Capturing single pulse signal should follow these steps.
1) connect Ch1 to signal
2) successively press , then select sampling mode as peak
3) press to open the trigger menu
4) press to select the trigger type as the edge trigger
5) Press to select signal source as Ch1
