ESG Series Signal Generator Instrument-Specific Error Messages
514 Reference Oven cold
Indicates that the reference oven is not at the required operating
temperature. This is normal if the instrument has been powered
down for a while. If the error persists, the instrument may
require service.
515
Reference board: 10 Mhz reference signal bad or
missing
Indicates that the instrument’s reference is unlocked. If an
external reference is connected, check the frequency and
power. It is possible for this to occur during a poor
connection/disconnection of an external reference. If this error
reoccurs when no external reference is connected, the
instrument may require service.
517
Calibration failure;DCFM DC overrange
Indicates that the instrument was unable to perform a DCFM or
DC
ΦM calibration due to the input signal being outside of the
offset range that can be calibrated for.
Calibration failure;Upgrade calibration
failed. Data not stored.
Indicates that the calibration stage of the instrument upgrade
was not executed successfully. The calibration data has not
been stored. The upgrade is not functional. Contact the nearest
HP Sales and Service office.
600
RPP has tripped.
Indicates that the reverse power protection circuit has been
triggered. Repeated tripping of this circuit can cause damage to
the instrument.
601
Power search failed.
Indicates that, while executing power search, the level meter
circuit failed to return a meaningful value. This event indicates
that the power is in a range that the leveling loop cannot
properly level. The power will be set to the last properly leveled
power.
