make a check on the instrument according to the following steps:
1. Check whether there is any damage caused by transportation.
If it is found that the packaging carton or the foamed plastic protection cushion has
suffered serious damage, do not throw it away first till the complete device and its
accessories succeed in the electrical and mechanical property tests.
2. Check the Accessories
The supplied accessories have been already described in the Appendix B
“Accessories” of this Manual. You can check whether there is any loss of accessories
with reference to this description. If it is found that there is any accessory lost or
damaged, please get in touch with the distributor of LILLIPUT responsible for this
service or the LILLIPUT’s local offices.
3. Check the Complete Instrument
If it is found that there is damage to the appearance of the instrument, or the
instrument can not work normally, or fails in the performance test, please get in touch
with the LILLIPUT’s distributor responsible for this business or the LILLIPUT’s
local offices. If there is damage to the instrument caused by the transportation, please
keep the package. With the transportation department or the LILLIPUT’s distributor
responsible for this business informed about it, a repairing or replacement of the

How to Implement the Probe Compensation
When connect the probe with any input channel for the first time, make this
adjustment to match the probe with the input channel. The probe which is not
compensated or presents a compensation deviation will result in the measuring error
or mistake. For adjusting the probe compensation, please carry out the following
steps:
1. Set the attenuation coefficient of the probe in the menu as 10X and that of the
switch in the probe as 10X, and connect the oscilloscope probe with the CH1
channel. If a probe hook tip is used, ensure that it keeps in close touch with the
probe. Connect the probe tip with the signal connector of the probe compensator
and connect the reference wire clamp with the ground wire connector of the
probe connector, and then press the button “7(AUTOSET)”.
2. Check the displayed wave forms and regulate the probe till a correct
compensation is achieved (see Fig. 5 and Fig. 6).

Fig. 5 Displayed Wave Forms of the Probe Compensation
3. Repeat the steps mentioned if necessary.
Fig. 6 Adjust Probe
How to Set the Probe Attenuation Coefficient
The probe has several attenuation coefficients, which will influence the vertical scale
factor of the oscilloscope.
If it is required to change (check) the set value of the probe attenuation coefficient,
press the function menu button of the channels used, then push down the selection
button corresponding to the probe till the correct set value is shown.
This setting will be valid all the time before it is changed again.
Note: The attenuation coefficient of the probe in the menu is preset to 10X when
the oscilloscope is delivered from the factory.
Make sure that the set value of the attenuation switch in the T5100 probe is the same
as the menu selection of the probe in the oscilloscope.
The set values of the probe switch are 1X and 10X (see Fig. 7).
18
User’s Manual of OWON Color Mixed Signal Digital Storage Oscilloscope
Fig. 7 Attenuation Switch
Note: When the attenuation switch is set to 1X, the T5100 probe will limit the
bandwidth of the oscilloscope in 5MHz. If it is needed to use the whole bandwidth
of the oscilloscope, the switch must be set to 10X.
How to Use the Probe Safely
The safety guard ring around the probe body protects your finger against the electric
shock, shown as Fig. 8.
Fig. 8 Finger Guard
Warning: In order to avoid suffering from the electric shock, please keep your
finger behind the safety guard ring of the probe body during the operation.
In order to protect you from suffering from the electric shock during your using the
probe, do not touch the metal part of the probe tip when the probe is connected to
the power supply.
Before making any measurements, please connect the probe to the instrument and
connect the ground terminal to the earth.
How to Implement Auto-calibration
The auto-calibration application can make the oscilloscope reach the optimum
condition rapidly to obtain the most accurate measurement value. You can carry out
this application program at any time, but when the range of variation of the ambient
temperature is up to or over 5℃, this program must be executed.
For the performing of the self-calibration, all probes or wires should be disconnected
with the input connector first. Then, press the “8(UTILITY)” button to call out the
FUNCTION menu; push down the F3 menu selection button to choose the option
19

“ Do Self Cal”; finally, run the program after confirming that everything is ready now.
Introduction to the Vertical System
Shown as Fig.9, there are a series of buttons and knobs in VERTICAL CONTROLS.
The following practices will gradually direct you to be familiar with the using of the
vertical setting.
Fig. 9 Vertical Control Zone
1. Use the button “VERTICAL POSITION” knob to show the signal in the center
of the waveform window. The “VERTICAL POSITION” knob functions the
regulating of the vertical display position of the signal. Thus, when the
“VERTICAL POSITION” knob is rotated, the pointer of the earth datum point
of the channel is directed to move up and down following the wave form.
Measuring Skill
If the channel is under the DC coupling mode, you can rapidly measure the DC
component of the signal through the observation of the difference between the wave
form and the signal ground.
If the channel is under the AC mode, the DC component will be removed by filtration.
This mode helps you display the AC component of the signal with a higher
sensitivity.
2. Change the Vertical Setting and Observe the Consequent State Information
Change.
With the information displayed in the status bar at the bottom of the waveform
window, you can determine any changes in the channel vertical scale factor.

How to acquire data
When you start to acquire LA begins sampling data from the probes. Then each time
clock occurs the data will be sampled.
Then sampled data is sent to trigger function block and store in main memory. The
trigger program checks specific events with the sampled data and take specific action. The
trigger program can check events as rising edge, data values, and data ranges etc. LA
module enables a post trigger delay counter when trigger reach specified value and to
allow post trigger portion of the acquisition memory to fill before data acquisition stops.
Press “F” to get into data acquisition mode after finish setting for trigger and
sampling. Then running status display as “RUN” and running status display “TRIG”
when detected trigger signal and display “STOP” when data acquisition finished. Then
you can start to analyze data. Data acquisition can be stopped by press “F” again during
the process.
Note:
When running status display as “RUN”、“TRIG” during data acquiring
process ,only "F" key for operate and other keys or knobs are idle. Only
till status display as "STOP" then others operation are working.
How to observe and analyze the data
Follow up below steps to observe and analyze the current data acquired:
1、Turn “Sec/Div” knob to adjust the time length for data display in each division (to
adjust the data resolution displayed).
2、Turn “Cursor” knob to observe more details for the data of current cursor position.
The data of binary value for current cursor position display in binary system
area and power on measure menu then bus value for current cursor position will
display in measurement window.
3、Turn “horizontal position” knob can move the current displayed data to left/right
position in storage area quickly.

We will use a simple measurement example to explain the primary setting for LA
measurement.
We need to measure a three lines SPI signal, three signal are enable, clock and data.
Clock is in effect when enable is low clock data, and clock frequency is 1M, data width is
32 digits, every clock corresponds to one data. Signal voltage is 3.3V.
Display systems
We need only three channels as what we measure is 3 signals. And other channel and
bus can be off. In this way the display resolution in using channel will be increased.
Display system mainly to set on/off for measure channel. We use CH00、CH01、
CH02 as measure channel correspond to signal enable, clock, data accordingly. Other
channel and bus is off.
1、Press “A（DISPLAY）” and display menu appears.
2. Press “F1” till signal sources display as“Channel”
3. Press “F2” or turn “CH1 Volts/Div” knob till channel No. display as “CH00”.
4. Press “F3” and set the signal sources as “ON”. Repeat operation of steps 3.4 and
set CH01, CH02 as “ON” and CH03-CHOF as “OFF”. Refer to fig. 13
5. Press “F1” till sources display as“ BUS”.
6. Press “F2” till Bus No. display as“BUS0”
7. Press “F3” and set signal sources as “OFF”. Repeat operation of steps 6.7 and
set BUS1、BUS2、BUS3 all as “OFF”. Ref to fig. 14
Now display panel only show CH00、CH01、CH02 and others channel and bus are all off.

Trigger system
LA is same as DSO and need to make trigger to synchronize data. The trigger system
mainly to set trigger sources, trigger mode and trigger position.
We make CH00 as trigger source and trigger mode as falling edge, trigger position in
50%. Trigger system setting steps as below
1. Press “Trig menu” and menu appears.
2. Press “F1” till trigger mode display as “Edge”.
3. Press “F2” or turn “CH1 Volts/Div” till trigger sources display as “CH00”.
4. Press “F3” till trigger type display as “Falling”.
5. Turn “Trigger adjust” knob or press “SET 50%”till “NEXT T POS” window
display as “50%”

Threshold voltage system
Threshold voltage system is to set high/low of the trigger voltage. The system already
fixed the setting for normal logic voltage as CMOS, LVMOS etc. And you can set any
trigger voltage using custom setting.
The signal voltage is 3.3V and we set threshold voltage as “LVCMO3.3/1.7V” as
below steps:
1. Press “1 (Threshold)” key and the menu appears.
2. Press “F1” key till Channel display as “CH00～CH03”
3. Press “F2” key till threshold display as “LVCMOS3.3/1.7V”.
Then the threshold setting is finished (ref to fig. 17).

Sampling system
The waveform accuracy reverts from sample data depend on sample rate for
measured signals. The waveform reverted in LA is referring to the sample signals storage

User’s Manual of OWON Color Mixed Signal Digital Storage Oscilloscope
in the memory. The recorded data will display in error if the sample rate is too lower.
Below figures explains how sample rate influence the waveform recorded in LA.
Figure 18
There is an importance compromise between recorded signal resolution and its
continuance (relate to time). The sample memory depth of LA is fixed and once adding
sample rate then resolution will get better accordingly. But it will decrease the
continuance for acquire signal. In a word, sample rate are quicker then the continuance for
recorded signal will get smaller but with better resolution.
Sampling system can set difference sample rate and storage depth.
We use 10 times sampling rate to measure the signal clock frequency of 1M. and
storage depth set as “Normal”. Sampling system setting steps as below:
1. Press “E(ACQUIRE)” and menu appears.
2. Press “F1” or turn “CH1 Volts/div” knob till sample rate setting display as“10M”.
3. Press “F2” till storage depth display as “General”.
Sampling system setting finished (ref to the fig.)
Then press “F” and start to sampling data. Display show as fig. 19 when sampling
finished.
