data can be set to equal, greater, or less than the set data.
Press RETURN option key to return to the previous menu.
Trigger Setting: Set the trigger selection.
Use this option to enter the trigger setting menu. The trigger mode can be set to auto or normal. The trigger coupling can be set to: DC, AC,
low frequency, high frequency suppression, and noise suppression. Press the RETURN to return to the previous menu.
If a more detailed communication analysis is needed, the UPO 2000CS protocol decoding function can be used. The oscilloscope will
capture the continuous communication data. The communication data can be displayed directly by the screen or in event list to make
communication analysis quicker, more accurate, and more convenient.
Bus Setting: Use this option to enter decode bus settings:
Bus Status: Use this function to enable bus control selection list, to open or close the decoding function. You can also operate using the
Multipurpose
knob after the selection list pops up.
Display Format: Use this feature and the display format can be switched between hexadecimal, decimal, and binary. The
Multipurpose knob can also be used after the selection list pops up.
Event List: The event list can be open or closed using this feature. We can also operate through the Multipurpose knob.
The event list contains the decoded data for continuous collection which can be directly displayed on the screen,
which contains data capture time, data content, and parity status
Pseudo Square Wave: The pseudo wave function can be open or closed using this feature. The Multipurpose knob
can also be used after opening the function list. The waveform is displayed using the 0/1 collected by the oscilloscope.
This feature is useful when the input wave is severely distorted.
Press the NEXT PAGE option key to enter the following settings:
Vertical Position: Use this feature and rotate the Multipurpose knob to adjust the position of decoded data on the
screen.
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 decoded 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 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 the figure below. The oscilloscope is set up as follows. SCL selection is CH1. SDA selection
is CH2. The condition is Addr. The set address is 7bits, 0x48 and the direction is writing. The data do not need to be set
because data trigger is used.
The bus status is open during setting the bus. The displayed format is ASCII. Open the event selection and the
