RF Burst Amplitude Alignment
RF Burst alignment calibrates the circuitry to provide accurate external RF Burst
triggering. Learn more about RF Burst triggering on page 100.
When 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 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 on page 94.
The alignment process can be disabled. You may want to do this, for example, if
you are analyzing the amplitude stability of a signal.
