Phase Settling Time
Phase Settling Time
The time measured from a reference point to when the signal of interest settles to within user-de
fi
ned
tolerance.
PM
Acronym for Phase Modulation.
Primary Marker
The marker displayed in the Single Marker mode whose frequency and/or position is changed when
tuning with the general purpose knob.
PSK
Acronym for Phase Shift Keying. The process, or result of a process, in which the carrier phase is varied
discretely in accordance with a digital code.
QAM
Acronym for Quadrature Amplitude Modulation. The process, or result of a process, in which the amplitude
and phase of the carrier are varied concurrently by synthesizing two orthogonal ASK waves (see ASK).
Real-Time Analysis
Measurement technique based on triggering on an RF signal, seamlessly capturing it into memory, and
analyzing it in the frequency, time, and modulation domains.
Real-Time Bandwidth
The frequency span over which real-time seamless capture can be performed, which is a function of the
digitizer and the IF bandwidth of a Real-Time Spectrum Analyzer.
