TRIGger:PULSe:POLarity For example, :TRIGger: PULSe: POLarity POSItive /*Set positive pulse trigger*/ :TRIGger: PULSe: POLarity? /*The query returns POSItive*/ :TRIGger:PULSe:WHEN For example, 70 / 136 Function description Set or query the trigger source of the pulse width trigger. Parameter Name Type Range Default Discrete {D10|D11|D12|D13|D20|D21|D22|D23|D 30|D31|D32|D33|D40|D41|D42|D43| CHANnel1|CHANnel2|CHANnel3|CHANnel 4} CHANnel1 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:PULSe:POLarity :TRIGger:PULSe:POLarity? Function description Set or query the trigger polarity of pulse width trigger Parameter Name Type Range Default Discrete POSItive Description POSItive: Positive pulse trigger NEGAtive: negative pulse trigger Return format The query returns POSItive, NEGAtive Command format :TRIGger:PULSe:WHEN :TRIGger:PULSe:WHEN? Function description Set or query the trigger conditions for pulse width trigger.
Parameter Name Type Range Default Discrete { EQUAl| NEQUal| GREAt| LESS } EQUAl Description EQUAl = (equal to time value): Only when the positive or negative pulse width of the input signal is equal to the set pulse width can it trigger. [Pulse width error is 5%] NEQUal! = (Not equal to time value): Only when the positive or negative pulse width of the input signal is not equal to the set pulse width, can the [pulse width error be 5%] be triggered. GREAt ＞ (greater than the time value): Only when the positive or negative pulse width of the input signal is greater than the set pulse width can it trigger [pulse width error is 5%]. LESS Return format The query returns EQUAl, NEQUal, GRAt, LESS
