Never mind, found the answer I was looking for. A: Institutional Revolutionary Party
Background: PRI = Pulse Rate Interval. PRI is a term used in Radio Frequency (RF) systems. Specifically, Pulse mode RF systems, as apposed to continuous wave (CW) systems. Each pulse has an on period, pulse width (PW), and an off period. PRI is the time from the start of one pulse to the start of the next pulse. For example, if a pulse on time is 10 microseconds (uSec) and the off time is 90 uSec then the PRI is 100 uSec. Answer: A staggered PRI does not have a constant on and off time. The off time varies.
Partido Revolucionario Institucional - Institutional Revolutionary Party. It is a center-right party that surprisingly, does not have an actual political platform.
