Understanding Modulation Analysis
What the Modulation Analysis Measurement Personality and Hardware Does
The ESA spectrum analyzer with modulation analysis measurement personality is
capable of making the following measurements:
Peak and RMS EVM
•
Peak and RMS magnitude error
•
Peak and RMS phase error
•
Frequency Error
•
• Phase error/symbol display
Magnitude error versus symbol display
•
Polar vector display
•
Polar constellation display
•
I and Q eye display
•
I/Q Offset
•
Amplitude Droop error
•
In addition to the measurements listed above, the modulation analysis personality
provides or uses the following supplemental functions:
Wideband Calibration which allows the user to effectively perform a
•
factory calibration on the analyzer's front end.
Automatic signal level detection and analyzer setup.
•
External reference configuration and control.
•
Save and recall mode state (Mode is the operation mode of the
•
instrument
. For example: SA = Spectrum Analyzer or MAN = Modulation
Analysis Measurement personality
Storing/printing of results internally or directly to a floppy disk in
•
spreadsheet (.csv) format.
