pseudo random binary sequence (PRBS)
Semiconductors; Test equipment
A set of sequences,which consists of a stream of numbers that appear random but follow a predictable mathematical pattern, repeated at a random rate; used to create random noise ...
programmable read-only memory (PROM)
Semiconductors; Test equipment
A programmable logic device in which the OR array is programmable but the AND array is pre-defined. Usually considered to be a memory device whose contents can be electrically ...
pseudo random pattern generator (PRPG)
Semiconductors; Test equipment
PRPGs are LFSRs that are sometimes used on the front end of BIST engines to generate pseudo-random patterns to be presented to a circuit under test.
pseudo-random word stream (PRWS)
Semiconductors; Test equipment
A word stream that defines how multiple pseudorandom bit streams are presented across all of the signal generator’s parallel outputs, often used when testing serializers or ...
phase-shift keying (PSK)
Semiconductors; Test equipment
Digital modulation where the carrier switches between two phase settings. In PSK, a “0” is imparted by sending a signal of the same phase as the previous signal, while a “1” bit ...
plated through hole (PTH)
Semiconductors; Test equipment
(1) A hole in a double-sided or multilayer board that is used to accommodate a through-hole component lead and is plated with copper. (2) An alternative name for the lead ...
precision time protocol (PTP)
Semiconductors; Test equipment
The name used in the IEEE-1588 standard for the protocol.
