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. -
Page 20: Sampling Rate
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. Analog Singal Sampling Points Sampling rate refers to the time interval between two sampling points. -

Page 35: Chapter 6 Protocol Decoding
Chapter 6 Protocol Decoding UPO2000E decodes the input signals of the analog channels using common protocols, including parallel, RS232, I2C, SPI. Users can easily find errors, debug hardware, and speed up development progress by protocol decoding, which provides guarantees for completing projects with high speed and high quality. 6.1 RS232 Decoding RS232 interface is the standard asynchronous transmission interface established by Electronic Industries Association. - Page 36 Baud Rate: RS232 communication is an asynchronous transmission communication without clock signals during the data transmission process. In order to solve the data bit problems, the protocol specifies that both communication parties need to agree on the baud rate. Normally, the baud rate is defined as bits transmitted within 1 second. For example, 9600bps means that 9600 bits can be transmitted within 1 second.
