For example, :TRIGger:EDGe:SOURce CHANnel1 / * Set the trigger source to CH1 * / :TRIGger:EDGe:SOURce? / * The query returns CHAN1 * / :TRIGger:EDGe: SLOPe For example, :TRIGger:EDGe:SLOPe NEGative /*Set the edge type to falling edge*/ :TRIGger:EDGe:SLOPe? /*The query returns NEG*/ : TRIGger: EDGe: LEVel For example, :TRIGger:EDGe:LEVel 0.16 /*Set the trigger level to 160mV*/ :TRIGger:EDGe:LEVel? /*The query returns 1.600000e-01*/ :TRIGger:PULSe :TRIGger:PULSe:SOURce 69 / 136 CHANnel1|CHANnel2|CHANnel3|CHANnel4} Description When the digital channel is used as the trigger source channel, the digital probe must be connected to the oscilloscope.
Return format The query returns D10, D11, D12, D13, D20, D21, D22, D23, D30, D31, D32, D33, D40, D41, D42, D43, CHAN1, CHAN2, CHAN3, CHAN4. Command format :TRIGger:EDGe:SLOPe :TRIGger:EDGe:SLOPe? Function description Set or query the edge type of edge trigger. Parameter Name Type Range Default Discrete RISIng Description POSitive: rising edge NEGative: falling edge EITHer: rising or falling edge Return format The query returns POS, NEG or RFAL Command format :TRIGger:EDGe:LEVel :TRIGger:EDGe:LEVel? Function description Set or query the trigger level when the edge triggers. The unit is the same as the current amplitude unit of the selected source.
Parameter Name Type Range Default Integer (-5×VerticalScale-OFFSet) to (5× VerticalScale-OFFSet) 0 Description This setting command is valid only when the selected source is an analog channel. Return format The query returns the trigger level value in scientific notation. Command format :TRIGger:PULSe:SOURce :TRIGger:PULSe:SOURce?
