Parker EME Setting up Compax3192-120114 N5 C3I22T11 June 2008 1674.3.2.3 Example: Setting the OscilloscopeSINGLE measurement with 2 channels and logic trigger on digital in-putsThe order of the steps is not mandatory, but provides a help for better understan-ding.As a rule, all settings can be changed during a measurement. This will lead to anautomatic interruption of the current measurement and to a re-start of the measu-rement with the new settings:Assumption: A test movement in the commissioning mode is active.1.) Select OSCI operating mode2.) Select Time basis XDIV3.) Select channel 1 signal source digital inputs 120.2 from status tree withthe aid of Drag & Drop4.) Select channel 2 (filtered actual speed) via "Drag and drop" from the sta-tus tree5.) Set trigger to channel 1 and DG.Input of the mask in HEXTriggering a rising edge to input I1.BIT 0 (value 1) = I0BIT 1 (value 2) = I1BIT 2 (value 4) = I2 etc.Trigger to input I0 I1 I2 I3 I4 I5 I6 I7Trigger mask in hex 1 2 4 8 10 20 40 80The masks can also be combined so that the trigger is only active, if several inputsare active. Example: Triggering to I2 and I5 and I6 -> 4h + 20h + 40h = 64hThe mask for input I1 is in this case 2.select rising edge.Note: If the trigger mask DG (digital) is selected for a channel, the display mode ofthe trigger channel is automatically set to DIG display.6.) Start measurement7.) Set pretrigger in the OSCI windowNote: There is no level for the DIG trigger The the event lomit determines the maskIf a trigger event occurs, the measurement values are captured until the measure-ment is completed.Afterwards, the measurement values are read from the Compax3 and displayed.The display mask of trigger channel 1 was not yet limited, therefore it shows all 16bit tracks (b0...b15). In order to limit it to 8 bit tracks, you must call up the menu forchannel 1 via [CH1] and select "change logic of display mask [H].Limit the display mask to 8 bit tracks with Mask FFh.In the display the bit tracks b0 to b7 are now shown:
