SA (Spectrum Analyzer) Mode
SA Mode Settings
When All Alignment is enabled (by default) the FieldFox performs an
alignment process using the internal RF source. Although some sweeps are
delayed, measurement results are never disturbed.
If the Independent Source (tracking generator) is enabled for your
measurement, it will be borrowed to perform the alignment. Again, the
measurement results are not disturbed. Learn about the Independent Source in
“Independent Source/Tracking Generator ” on page 163.
The alignment process can be disabled. You may want to do this, for example,
if you are analyzing the amplitude stability of a signal.
SA and all modes built on its infrastructure require three types of alignments:
— InstAlign Amplitude Alignment
— RF Burst Amplitude Alignment
— Channel Equalization
These are referred to as Individual Align
.
All three or a subset of the individual alignments are required for each specific
mode, depending on the type of measurement supported by it:
SA:
— InstAlign Amplitude Alignment
— RF Burst Amplitude Alignment
RTSA:
— InstAlign Amplitude Alignment
— RF Burst Amplitude Alignment
— Channel Equalization
Channel Scanner:
— InstAlign Amplitude Alignment
ERTA:
— InstAlign Amplitude Alignment
IQA:
— InstAlign Amplitude Alignment
— RF Burst Amplitude Alignment
— Channel Equalization
Built-in Power meter
— InstAlign Amplitude Alignment
