Sampling Oscillator (355)
This error indicates an unlocked sampling oscillator
during the local oscillator (LO) alignment routine. This
error only applies to the hardware in an 8560 E-series
or EC-series spectrum analyzer.
355 SMP CAL Sampler unlock condition during calibration routine.
This error remains until a successful recalibration is
performed.
Span Accuracy Calibration Errors (356 to 361)
These errors are generated when the span accuracy
calibration fails. The span accuracy calibration is done
during "power up", IF calibration (every 5 minutes),
and LO IF realignment routines. Span accuracy
calibration sweeps occur during the retrace (dead time)
of the main sweep ramp. The firmware then detects any
span accuracy calibration errors. These errors only
apply to firmware revisions 931216 and later.
356 SPAC CAL Sweep data problem finding "bucket 1" of the span
accuracy calibration sweep. This error indicates a
possible failure of the sweep generator, span
attenuator, or main/FM coil sweep switches on the A14
frequency control assembly. Refer to
"Synthesizer Section."
357 SPAC CAL Cannot find the "x" intersection for "bucket 1" of the
span accuracy calibration sweep. This error indicates a
possible failure of the sweep generator, span
attenuator, or main/FM coil sweep switches on the A14
frequency control assembly. Refer to
"Synthesizer Section."
358 SPAC CAL Sweep data problem finding "bucket 2" of the span
accuracy calibration sweep. This error indicates a
possible failure of the sweep generator, span
attenuator, or main/FM coil sweep switches on the A14
frequency control assembly. Refer to
"Synthesizer Section."
359 SPAC CAL Cannot find "x" intersection for "bucket 2" of the span
accuracy calibration sweep. This error indicates a
possible failure of the sweep generator, span
attenuator, or main/FM coil sweep switches on the A14
frequency control assembly. Refer to
"Synthesizer Section."
