ARM[:STARt]:SLOPe[<n >]

∙When POSitive and NEGative voltage levels are specified, the levels must be separated by an amount defined by:

(50 mV / 1.0235V) * measurement range

This accounts for offset errors in the levels specified, and enables arms at those levels to be accepted.

∙Related Commands: ARM:STARt:SOURce<n>, ARM:STARt:SLOPe<n>

∙*RST Condition: ARM:STARt:LEVel<n >:POS 1.022418

Example Setup to arm when the signal on channel 1 goes outside of a the window bounded by 0.5V and 0V.

ARM:SOUR1 INT1	Set arming source 1 to be channel 1 level(s).
ARM:LEV1:POS 0.50
ARM:LEV1:NEG 0
ARM:SLOP1 EITH	Specify that both ARM:LEVel1:POS and
	ARM:LEVel1:NEG will be used to form a
	window. If the signal rises above the 0.5
	volt level (the POSitive slope level
	specified), or falls below the 0 volt level (the
	NEGative slope level specified), arming will
	occur and the measurement will proceed.

[:STARt]:SLOPe[<n >]

ARM[:STARt]:SLOPe[<n >] <edge > selects which edge - POSitive, NEGative, or EITHer on arming source <n > will cause the arm event to occur. ARM:STARt:SLOPe is only active when either of the two arm sources is set to EXTernal1, INTernal1, or INTernal2. The "EITHer" setting may be used only when the corresponding ARM:STARt:SOURce is set to INTernal<n >. The "EITHer" setting causes the window specified by ARM:STARt:LEVel<chan>:POSitive and ARM:STARt:LEVel<chan>:NEGative to be in effect.
