UPO2000CS series User Manual
48
The Trigger Coupling can be set: DC, AC, low frequency, high frequency suppression, and noise suppression. Press the
RETURN to return to first level menu.
If you need more detailed communication analysis, you can use UPO2000CS protocol decoding function. The
oscilloscope will capture the continuous communication data. The communication content can be displayed by the
screen or the event list.
Bus Setting: Press PRESS SETTING to enter the decoding bus setting.
Bus Status: Press the button BUS STATUS, and the bus control selection list pops up. The decoding function can be open or closed. The
knob can also
Multipurpose set it.
Display Format: Press the button DISPLAY FORMAT, and then there are four kinds of display methods to switch: hexadecimal, decimal,
and binary and ASCII. The knob
Multipurpose can also set it after the list pops up.
Event List: Press the button EVENT LIST, and the decoding events can be open or closed. The knob Multipurpose can also set it after
the list pops up.
Pseudo Square Wave: Select this option and the pseudo square wave function can be open and closed. The knob Multipurpose
can also set it after the list pops up. The pseudo square wave displays 0/1 collected by oscilloscope. The function can display logic 0 and
logic 1 on the screen under the condition that the input waveform is severely distorted.
Press the NEXT PAGE to enter the following settings.
Vertical Position: Press the button and rotate the knob Multipurpose, which can adjust the position of decoding data
on the screen. It is convenient for you to observe the waveform and decoding data.
Event List Check: When the oscilloscope is in the state of decoding, RUN/STOP is green. At the moment when
pressing RUN/STOP, RUN/STOP is red. The oscilloscope will stop refreshing waveform and the collected data will be
stored in the oscilloscope. The menu will display decoding data selection. The button displays the times of captured
transmission signal and the corresponding number of the present selected data. The selected decoding data will be
highlighted in green. The Multipurpose knob can select any collected data. This function can find the content of
captured multiple transmission communication and help to debug the system conveniently.
Input the signal as shown in the following picture. Set the oscilloscope according to the following.
CS source is CH1. The CS polarity is negative. SCLK source is CH2. The SCLK edge is rising edge. MOSI source is CH3. The
MOSI polarity is positive. MISO source is OFF. The condition is CS. The bit order is MSB in the condition setting. Data
setting and idle time do not need to be set.
The bus state is open in the bus setting. The display format is ASCII. The event list is open, and the result is as shown in
the following picture.
