ESG-D Series Signal Generator Instrument-Specific Error Messages

513 Het VCO unlocked

Indicates that the VCO used to generate output frequencies below 250 MHz is unlocked.

The instrument may require service.

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.

516

Baseband Generator unlocked; refer to manual.

Indicates that the digital modulation board is unlocked. If this error occurs and the status

indicator on the front panel is not on, the board is operational. There are legitimate

reasons for the front panel indicator to be on: if External Data mode was selected and no

clock was provided for the data clock input, or if there was an incorrect setting selected

for data clock/symbol clock.

517

Calibration failure;DCFM DC overrange

Indicates that the instrument was unable to perform a DCFM or DCM 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.

Calibration failure;Cal aborted by user.

Indicates that, while executing the internal I/Q calibration, the user sent a DCAS over

the HP-IB or pressed the

Abort key on the front panel.

Calibration failure;I/Q cal failed to allocate memory.

Indicates that, while executing the internal I/Q calibration, the attempt to allocate

memory for the calibration failed.
