NEGAtive indicates that a pulse edge must traverse from the upper (most
positive) to lower (most negative) level for slew rate triggering to occur.
POSITIVe indicates that a pulse edge must traverse from the lower (most
negative) to higher (most positive) level for slew rate triggering to occur.
EITher indicates either NEGAtive or POSITIVe polarity.
TRIGGER:MAIN:PULSE:SLEwrate:POLARITY EITHER
specifies that the polarity of the slew rate can be either positive or negative.
TRIGger:MAIn:PULse:SLEwrate:SLEwrate? (Query Only)
TDS 684A & 7XXA Only
Returns the slew rate value. This is the
((Upper Threshold – Lower Threshold) / Delta Time)
The value is limited to the three most significant digits.
