ROM 2 check error
7010
FFS is unlocked
Fractional-frequency-source is unlocked
Cause: The frequency synthesizer is not able to acquire phase lock. If an external frequency
reference is being used, verify that the frequency is accurate. If not, it is likely that the LO
hardware has failed.
Cure: Correct external frequency reference accuracy or return to Hewlett-Packard for
servicing.
7011
125 KZ to FFS
125 kHz to fractional frequency source error
Cause:
The
internal
125
kHz
reference
signal is not at the correct power level on the Fractional
Frequency Synthesizer assembly. This error will only occur on power up of the system, or
when the TEST command is invoked, either from the front panel or remotely.
Cure: Return to Hewlett-Packard for servicing.
7012
Cannot lock YTO
Cannot
lock
YIG-tuned
oscillator
Cause:
The
Local
Oscillator
cannot
acquire
phase
lock.
If
an
external
frequency reference is
being used, verify that the frequency is accurate. If not, it is likely that the LO hardware has
failed or is in need of calibration.
Cure: Verify the external reference frequency is operating correctly.Ifitis, return the LO
module
to
Hewlett-Packard for servicing.
7013
Can't finetune YTO
Cannot ne-tune YIG-tuned oscillator
Cause: The Local Oscillator cannot be adjusted for proper operation. Module service or
calibration is required.
Cure: Return to Hewlett-Packard for servicing.
