ENT AN 105

spectrum analyser (CATV-A/E, p. 85)

IN ENT AN 110

syntagme nominal, sing.

DEF AN 115

An instrument generally used to display the power distribution of an incoming signal as a function of frequency. (IEEE-C/E)

CONT AN 120

RIN is the noise specification of the laser. It can be considered to be the noise floor, measurable with a spectrum analyser after light to current conversion with an optical detector. (CATV-A/E, p. 85)

NOTE AN 125

Spectrum analyzers are useful in analyzing the characteristics of electrical waveforms in general since, by repetitively sweeping through the frequency range of interest, they display all components of the signal. (IEEE-C/E)

ENT FR 205

analyseur de spectre (NENT-C; DELU-C/E/F)

IN ENT FR 210

syntagme nominal, m. sing.

DEF FR 215

Instrument servant généralement à indiquer la répartition de la puissance d'un signal incident en fonction de la fréquence. (T : IEEE-C/E)
