YTO Loop Settling Errors (351 to 354)
These errors are generated when the YTO loop error voltage will not
stabilize at an acceptable value during the YTO loop locking routines.
These errors only apply to the hardware in an HP 8560 E-Series
spectrum analyzer.
351 SETL FLD
YTO error voltage is not settling.
352 TWID FLD
Unable to bring YTO error voltage DAC’s to quiescent point.
353 SRCH FLD
No acceptable YTO DAC value found.
354 LK ITERS
Cannot lock. Lock iteration routine terminated.
Sampling Oscillator (355)
This error indicates an unlocked sampling oscillator during the local
oscillator (LO) 1 ga i nment routine. This error only applies to the
hardware in an HP 8560 E-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.

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
Al4 frequency control assembly. Refer to Chapter 11, “Synthesizer
Section.”
Cannot find the

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
Al4 frequency control assembly. Refer to Chapter 11, “Synthesizer
Section.”
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
Al4 frequency control assembly. Refer to Chapter 11, “Synthesizer
