12 /96
(1) Connecting to the Power Supply
AC power specification of UPO1000 series digital storage oscilloscope refers to Connecting Power
Supply section. Use the assembled power line or other power line that meets the local country
standards to connect the oscilloscope. The power soft indicator in the left bottom on front
panel is extinguished and this soft switch key is no-effect when the power switch on rear panel is not
opened. The power soft indicator in the left bottom on front panel is illuminated with red and
then press the soft switch key to enable the oscilloscope.
(2) Boot Check
Press the soft power key and the indicator should change from red to green. The oscilloscope
will show a boot animation, and then enter the normal interface.
(3) Connecting Probe
Use BNC of the port to connect to BNC of CH1 of the oscilloscope. Connecting the probe to the “probe
compensation signal connection clip” and connecting the ground alligator clip to the “ground terminal”
under the “probe compensation signal connection clip”. The output of probe compensation signal
connection clip is the amplitude about 3Vpp and the frequency defaults to 1 kHz.
Figure 4-1 Probe Compensation Signal Connection Clip and Ground Terminal
(4) Function Check
Press the AUTO key, a 3 Vpp, 1 kHz square wave should appear on the screen. Repeat step 3 to check all
channels.
(5) Probe Compensation
When the probe is connected to any input channel for the first time, this step might be adjusted to
match the probe and the input channel. Probes that are not compensated may lead to measurement
errors or mistake. Please follow the following steps.
Set the attenuation coefficient in the probe menu to 10x and the switch of the probe at 10x, and
connecting the probe of the oscilloscope to CH1. If use the probe’s hook head, make sure it stably
touch to the probe. Connecting the probe to the “probe compensation signal connection clip” and
connecting the ground alligator clip to the “ground terminal” under the “probe compensation signal
connection clip”. Open CH1 and press the AUTO key.
View the displayed waveform, as shown in Figure 4-2.

screen . The parameter can be changed by LEVEL (trigger control area) on front panel.
8.Operation menu: Display the current operation menu. Press the corresponding key to change the
operation menu. Press F1 ~ F6 can change the submenu.

11.CH1 vertical state label: Display the activation state, channel coupling, bandwidth limitation, vertical
scale, probe attenuation coefficient of CH1.
a. Activation state:
b. Bandwidth limitation: When the bandwidth limitation function is opened, a “B” icon will appear in
CH1 vertical state label.
c. Vertical scale: Display the vertical scale of CH1. When CH1 is activated, the vertical scale can be
changed by SCALE (vertical control area) on front panel. When the volts/div is changed, a popup
will display volts/div on the screen.
d. Probe attenuation coefficient: Display the probe attenuation coefficient of CH1, including 0.001X,
0.01X, 0.1X, 1X, 10X, 100X, 1000X, 2000X and user-defined.
e. Volts/div scale: When volts/div sets to fine tuning, a “ ” icon will appear in CH1 vertical state label.
12.Analog channel label and waveform: Display the channel icon and waveform of CH1~CH4, the channel
label is consistent with the waveform color.

Label
UPO1000 provides 4 analog input channels, which is CH1～CH4. The vertical system setup method
is exactly the same for each channel.
This chapter is take CH1 as an example to introduce the vertical channel setting.
5.1 Open/Activate/Close Analog Channel
CH1～CH4 analog channels includes three states open, close and activate.
Open: When the channel is closed, press any one of the channel 1, 2, 3 or 4 can open the
corresponding channel.
Close: Not display the channel’s waveform. The channel is opend but not activated, press the
corresponding channel key to close the channel.
Activate: When multiple channel are enabled, only one channel can be activated (should be in open
state). In the activation state, the vertical scale, vertical offset and channel setting can be adjusted.
Any one of the channel that have been opened but not activated could be activated by press the
corresponding channel key. When the channel is activated, the oscilloscope displays the channel’s
menu.
Activation state Open but not activated Close state
