Press the Source soft key to display one of the menus shown below. The menu that is displayed varies depending on the specified trigger source. When the Trigger Source Is a Channel from CH1 to CH8 Set the trigger source (CH1 to CH8). Set the trigger coupling, HF rejection, and noise rejection. ► section 2.3 Set the level used to detect source states. When the Trigger Source Is LOGIC(L) or LOGIC(A|B) Set the trigger source (LOGIC(L) or LOGIC(A|B)).* Set the source bit (L0 to L7, A0 to A7, B0 to B7).* Set the level used to detect source ...

Note Using the CH8 terminal and LOGIC (L) Port If you perform an analysis or execute a search when using the LOGIC (L) port for input, you cannot specify CH8 as the source. Press the CH8 key in advance to enable input from the CH8 terminal. Press the Setup soft key to display the following menu. Manual Setup During Automatic Setup Executes auto setup Set the bit rate (4800 bps, 9600 bps, 19200 bps, User Define). Set counter error detection on or off. Configure the detection level and the hysteresis. Set T Sample. Set the bit rate and clock ...

Press the List soft key to display the following menu. Set the list size and the display position (Full Screen, Half(Upper), Half(Lower)). Lists the analysis results Analysis number Turns zoom linking on or off Set the analysis number. Data before the trigger position (on the left side of the waveform display) is assigned analysis numbers in descending order (-1, -2, and so on). Data after the trigger position (on the right side of the waveform display) is assigned analysis numbers in ascending order (0, 1, 2, and so on). 12.2 Analyzing and ...
