Peak tuning range exceeds Hz. The maximum Peak Tuning Range is 500 kHz (or 200 MHz when
using a configured RF Analyzer).
Action: Reduce the Peak Tuning Range by reducing the Tuning Voltage or Tuning Constant value
defined for the VCO source in the Instrument Parameters display.
Plot range is not within span range. A Plotted Range has been defined that is not within the
Measurement Range specified in the segment tables.
Action: Define each of the Plotted Ranges in the Segment Table so they are each within the
Measurement Ranges defined in the table.
Range limits must be in ascending order. A segment has been defined with a lower limit greater
than the upper limit.
Action: Redefine the segment range so that the upper limit is greater than the lower limit.
Source specification is invalid and must be corrected. The system has detected an error
in the Source Controf definition.
Action: Check the Source Control Diagram for accuracy and compatibility with other parameters
defined for the measurement.
The currently defined measurement has not been properly calibrated. Select 'New
Msrmnt' or 'New Noise Monitor' to calibrate. The Phase Detector Constant or VCO Tuning
Constant has not been calibrated.
Action: Check that the appropriate calibration method has been defined in the Calibration Process
display. Select
New Msrmnt
or a
New Noise Monitor
to initiate calibration.
The frequency of the Internal 400 MHz Osc. cannot be tuned. The system cannot obtain
quadrature since the HP 11848A internal 400 MHz oscillator cannot be tuned.
Action: Use a tunable source or manually adjust quadrature using a phase shifter or line stretcher.
Tune line improperly connected. The Tune Line is connected to a non-tunable source in the
Source Control Diagram. A VCO source is required for Phase Lock Loop Measurements.
Action: Connect the Tune Line to a VCO source in the Source Control Diagram.
