Function description Set or query the pattern of each channel when the pattern is triggered. Parameter Name Type Range Default _ Discrete {H|L|X|} X _ Discrete {H|L|X|} X _ Discrete {H|L|X|} X _ Discrete {H|L|X|} X _ Discrete {H|L|X|} C … … … … _ Discrete {H|L|X|} C Description Parameters to set the pattern of the analog channels CH1 _ _ to CH4, and parameters to set the pattern of the digital _ _ channel. The user can send 20 parameters to set the pattern of all channels, or omit some parameters to set the pattern of some channels (the channel is omitted, the pattern status remains the same), but at least one parameter needs to be sent (the parameter sets CH1 Pattern).
When less than 20 parameters are sent, the instrument defaults to set CH1 to CH4 and D10 to D43 in turn. In the parameter value range, H means high level (above the threshold level of the channel), L means low level (below the threshold level of the channel), X means ignore this channel (this channel is not part of the pattern, when all channels are set to X, the oscilloscope will not trigger). Return format The query returns the pattern currently set for 4 analog channels or all channels. Multiple channels are separated by commas.
