Each Buffer Entry is controlled by a "buffer gate" that defines the start and end of the entry time interval. The gate signal may be internally or externally generated in several different ways.
Set the units for entering the pulse distal, mesial, and proximal levels. Many pulse measurements call for 10% to 90% voltage (which equates to 1% to 81% power) for rise time and falltime measurements, and measure pulse widths from the half-power (?3dB, 50% power, or 71% voltage) points.
Channel units. Voltage is calculated with reference to the sensor input impedance. Note that for ratiometric results, logarithmic units will always return dBr (dB relative) while linear units return percent.
