(5) Probe Compensation
When the probe is connected to any input channel for the first time, this step might be required in order to match the probe
and the input channel. Please follow the following steps:
Set the attenuation coefficient in the probe menu and the switch on the probe to “10x”, and connect the probe to
CH1. Make sure the probe’s hook is properly connected with the oscilloscope. Connect the probe to the probe
compensation signal connector and connect the probe’s ground alligator clip to the ground terminal respectively.
Open CH1 and press the AUTO button.

Excessive Compensation Correct Compensation Insufficient Compensation
Picture 1-2 Probe compensation calibration
If the displayed waveform does not look like the above “correct compensation” waveform, use a non-metallic
screwdriver to adjust the probe’s variable capacitance until the display matches the "correct compensation"
waveform.
Warning: To avoid electric shock when measuring high voltage using the probe, please ensure that the
probe insulation is in good condition and avoid physical contact with any metallic part of the probe.

a. Open: Press any of 1 , 2 , 3 , 4 under close state to open corresponding channel.
b. Close: No waveform displays on the corresponding channel. .For any opened and activated channel, pressing its
channel button can close that channel.
c. Activated: Only one channel in opened state will be activated when multiple channels are opened at the same time.
In the active state, the vertical menu and the vertical control knobs (POSITION, SCALE) are for changing activated
channel setting. Any of the channels that have been opened but not activated could be activated by the corresponding
channel keys, and displays the menu.

2.4 VOLTS/DIV
Press 1 → VOLTS/DIV → coarse tuning/fine tuning. Or press the SCALE knob to quickly switch between coarse
tuning/fine tuning.
In the coarse tuning, the VOLTS/DIV range is 1mV/div～20V/div by 1－2－5 steps.
For example: 10mV→20mV→50mV→100mV
In fine tuning, it adjusts in 1% of the current vertical scale.
For example：10.00mV→10.10mV→10.20mV→10.30mV
Note: div indicates the display area square, and one div represents one grid
2.5 Probe
In order to match the attenuation coefficient setting of the probe, the probe coefficient needs to be set up in the channel
operation menu. If the probe attenuation coefficient is 10:1, the probe coefficient should then be set to 10X to ensure
correct voltage reading.
Press 1 → probe to select 0.001X, 0.01X, 0.1X, 1X, 10X, 100X, and 1000X.
2.6 RP (Reverse Phase)
Press 1 →RP to turn on reverse phase. The waveform voltage value will be reversed, and the icon will appear in the
vertical bar.
Picture 2-1 RP Closed Picture 2-2 RP Open
2.7 Bias
When the DC component amplitude in the signal is relatively large, waveform observation could be very inconvenient.
Using the bias function and the superposition of a -1V bias voltage can eliminate the DC component so the AC signal can
be clearly observed, and at the same time user can know the DC component volume. As shown in picture 2-4,
press 1 →PgDn →Bias to turn on bias and rotate the Multipurpose knob countclockwise to adjust the value to -10V.
Picture 2-3 Bias off Picture 2-4 -1V bias on
Note: Press the Multipurpose knob to return the bias to zero.
2.8 Unit
Select the amplitude unit for the current channel. Press 1 → PgDn → Unit and adjust the Multipurpose knob to select
the unit of “V”, “A”,”W” or “U”, the default unit is V. User can also switch the channel units by consecutively pressing the unit
key, then press the Multipurpose knob to confirm, the correspoinding unit will appear on the channel status bar.

3.1 Horizontal scale
Horizontal scale, also the horizontal time base, is the time value represented by each scale in the horizontal direction,
which is usually expressed as s/div. With the SCALE knob in the horizontal control area, user can adjust the horizontal
scale in 1 – 2 – 5 steps, i.e. 5ns/div, 10ns/div, 20ns/div, 50ns/div……50s/div. Turn clockwise to decrease the scale and
turn counterclockwise to increase, the scale information on the upper left corner of the screen (as shown below) changes
in real time.
Chapter 3 Horizontal System Settings
When changing the horizontal time base, the waveform will expand or compress according to the trigger point position.
3.2 ROLL mode
When the trigger mode is auto, adjust SCALE knob in the horizontal control area to change the horizontal scale to be
slower than 50ms/div, and the oscilloscope will be in ROLL mode and will continuously plot the waveform voltage-time
trend chart on the screen. The earliest waveform first appears on the right end of the screen, and then gradually moves
to the left, as shown below:
Use the slow sweep mode to observe low frequency signal, and setting “channel coupling” method to “DC” is recommended.
Note: “Horizontal displacement”, “extended window”, “protocol decoding”, “pass/fail”, “parameter measurement”,
“waveform recording” and “independent time base” are not available in ROLL mode.

3.3 Extended Window
The extended window can be used to magnify a waveform horizontally to view the waveform details.
Press the HORI MENU button on the horizontal control area, then press the type key can turn on the extended window.
Or simply press the SCALE knob to directly enter the extended window, the screen will be divided into two display areas,
as shown below:
Waveform before magnification:
The upper part of the screen displays the original waveform, which can be moved left and right through rotating the
horizontal POSITION knob, or zoom in and out the selected area by rotating the horizontal SCALE knob.
Waveform before magnification:
The lower part of the screen displays the horizontally extended waveform, and the extended window enhances the
resolution relative to the main time base.
Note: The extended window function is only available when the horizontal time base is between 20ms/div~5us/div.
3.4 Independent Time Base
In independent time base, CH1~CH4 can be set as different time base scales so that signals of different frequencies can
be observed by multiple channels. Press HORI MENU →Time base setting to enter the independent time base
As shown below, CH1 is a 10Hz sine wave, CH2 is a 1kHz square wave, CH3 10kHz triangular wave, CH4 100kHz pulse
wave, so signals with great frequency difference can be observed simultaneously by independent time base. Press the
CH1 button to activate CH1, then user can change the CH1 time base scale by adjusting the horizontal SCALE knob, and
adjustment method for other channels are similar to this.

3.5 Trigger Hold-off
Trigger hold-off can observe the complex waveforms (such as pulse train). Hold-off time is the amount of time
the oscilloscope waits before re-enabling the trigger circuit. During the hold-off period, the oscilloscope will not
trigger until the hold-off time is over. For example, a set of pulse train, which is required to trigger on the first
pulse, the hold-off time can be set to the pulse train width.
Press the HORI MENU on the horizontal control area and then adjust the Multipurpose knob to set the trigger
hold-off time. Input a combined waveform to CH1, and adjust the trigger hold-off time until the waveform can be
triggered steadily, as shown below:

4.1 Sampling Rate
(1) Sampling and Sampling Rate
Sampling means that the oscilloscope samples the input analog signal, converts the sample to digital data, and
then the digital data will be collected into waveform records stored in the acquisition memory.
Sampling rate refers to the time interval between two sampling points. The maximum sampling rate of the UPO2000E
series is 1 GS/s.
The sampling rate will be affected by the time base scale and the memory depth. UPO2000E oscilloscopes displays the
sampling rate in real time at the top status bar, user can change the horizontal time base by adjusting the horizontal
SCALE knob or change the memory depth to change the sampling rate.
Analog Singal Sampling Points
(2) Low Sampling Rate Effect
a.W aveform Distortion: Due to low sampling rate, the details of the waveform might be missing, which makes a
great difference between sampling waveform and actual signal.
b. Wave Mixing: When the sampling rate is 2 times lower than the actual signal frequency (Nyquist frequency),
the frequency of the reconstructed signal will be less than the actual signal frequency.
