[:SENSe]:EVENt[12]:SLOPe POSitive NEGative

Sets or queries which edge of the input signal will be considered an event for Frequency, Period, Frequency Ratio, Time Interval, Totalize, and Phase measurements.

With the POSitive slope selected, a signal going from one voltage level to a more positive level, regardless of polarity, will define the event at the upper hysteresis limit. With the NEGative slope selected,

the negative going edge of the signal will define an event at the lower hysteresis limit.

Query Response A sequence of ASCII-encoded bytes: POS or NEG

Comments ∙ *RST: POSitive

The slopes used for Rise/Fall Time, Pulse Width, and Duty Cycle measurements are independent of this setting.
