Item dBm mW

Mesial value 10.0 10.0

Sample n 8.0 6.3

Sample n+1 11.0 12.6

The interpolated crossing time, tx, is calculated from:

where P is in watts and n is the number of the sampling interval, referenced to

the trigger event. For this example

11. The processor computes the rise and/or falltimes of waveforms that meet the

following conditions:

a) The waveform must have at least one usable edge (Types 2 through 7).

b) The signal peak must be at least 13 dB greater than the minimum sample

value.

The risetime is defined as the time between the proximal and distal crossings

( +).

The falltime is defined as the time between the distal and proximal crossings

(+ ).

If no samples lie between the proximal and distal values for either edge (rise or

fall), the risetime for that edge is set to 0 seconds
