RFA300A Measurement Set 8VSB
Glossary- 3
Phase Error
An error typically caused by variation of an amplifier’s phase changing
because of signal amplitude. The measurement set plots the signals
instantaneous phase error as a function of amplitude.
Phase Noise
A noise typically added to the digital modulation by the transmitter’s
frequency synthesizer system. The measurement set measures the pilot’s
phase noise.
Result
The outcome of a measurement in numeric, pass/fail, and graphic forms.
Results Database
A file where results from a measurement are held for later recall, exporting,
or reporting. Data in these files can also be used for further study or analysis
by external applications. The files are in Microsoft Access format.
Signal to Noise
The power ratio between the ideal received signal and the difference between
the ideal and actual received signal along the real axis.
Session
A collection of any results saved by the Signal Monitor during the time
between the Run and Stop events. A session can include a few results or the
results from many iterations through a set of measurements.
Setup
A collection of instrument control settings that includes measurement,
monitoring, and viewing parameters. Setups do not include any option
settings or system frequency selection.
