Gp Digital Modulation; Overview - Tektronix SPECMON3 Manual

GP Digital Modulation

Overview

The displays in the General Purpose (GP) Digital Modulation folder (Displays > Folders > GP Digital
Modulation) are:
Constellation
Demod I & Q vs Time
EVM vs Time
Eye Diagram
Frequency Deviation vs Time
Magnitude Error vs Time
Phase Error vs Time
Signal Quality
Symbol Table
Trellis Diagram
The General Purpose Digital Modulation Analysis (Option 21) provides vector signal analyzer
functionality. A wide variety of modulation types are supported, allowing you to view your signals in
Constellation, Eye and Trellis diagrams, measure the quality of the modulation, display time-domain
waveforms for demodulated I & Q signals, EVM, Phase Error, Magnitude Error, and more.
Modulation Measurements
NOTE. A maximum of approximately 80,000 samples can be analyzed by the General Purpose Digital
Modulation measurements (the actual value varies with modulation type).
