Agilent Technologies FieldFox N9913A - RF Burst Alignment

SA (Spectrum Analyzer) Mode 101
How to make Amplitude Alignment settings
These settings do NOT survive a Preset or Mode Preset.
 Press Cal 5
 Then Amptd Alignment
 Then choose from the following:
o Auto (Default setting) The alignment process is performed every 300
seconds or when the temperature has changed about 1 degree. It occurs only
at the beginning of a sweep and takes about 0.5 seconds to complete.
o OFF The alignment process is NOT performed. Only factory correction
values are used.
o Hold The alignment process is stopped, but the last alignment values are
applied to subsequent sweeps.
 Amptd Align Now An alignment is performed once and applied to subsequent
sweeps. If the FieldFox is not sweeping, a single sweep is triggered and
alignment is performed.
Amptd? is annotated in the lower left corner of the FieldFox screen when
amplitude alignment is questionable because this setting is in Hold or OFF.
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 94.
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 88.
The alignment process can be disabled. You may want to do this, for example, if
you are analyzing the amplitude stability of a signal.
How to make Burst Alignment settings
These settings do NOT survive a Preset or Mode Preset.
 Press Cal 5
 Then Burst Alignment
 Then choose from the following:
o Auto (Default setting) The alignment process is performed every 45 minutes
or when the temperature has changed about 3 degrees. It occurs only at the
beginning of a sweep and takes about 0.5 seconds to complete.
o OFF The alignment process is NOT performed. Only factory correction
values are used.
o Hold The alignment process is stopped, but the last alignment values are
applied to subsequent sweeps.
