Ref level
The setting defines the "Data ref level" for setup and hold measurements, and for time-
interval error measurements (option R&S
RTO6-K12). It selects the reference level of
the data signal on which the time is measured. The intersection of slope and reference
level defines the time point for measurements.
For clock jitter measurements (option R&S RTO6-K12), it sets the "Reference level" for
the time measurement.

Pulse count
Sets the number N of positive pulses for the "Pulse train" measurement. This measure-
ment measures the duration of N positive pulses from the rising edge of the first pulse
to the falling edge of the N-th pulse.
Remote command:
MEASurement<m>:AMPTime:PTCount

Edges slope
Sets the edge direction to be considered. The setting is relevant for edge count mea-
surement and delay measurement on digital channels.
"Positive" Positive edges are considered.
"Negative" Negative edges are considered.
"Either"
Both positive and negative edges are counted (edge count). Delay is
measured either between rising edges or between falling edges. The
first edge is taken for the measurement.

Delay to trigger measurement settings
Delay to trigger measures the time between the trigger point and the following slope of
a waveform. The delay between the trigger and the slope can be high compared to the
accuracy of the acquisition, and the trigger point can even be outside of the current
acquisition.
