Table 8-5. Status Messages (5 of 11)
Generating theoretical loop suppression... The system is fitting the theoretical response
generated from the calibration data and entered parameters to the measured response of the
loop suppression.
HP11848A INTERNAL ADJUSTMENTS... Indicates which adjustment is under test.
Action: Follow operation prompts, which appear in the display.
Illegal X,Y ranges specified... The graph parameters defined in the Define Graph display
are out of sequence.
Action: Redefine the values such that X-min < X-max and Y-min < Y-max.
Initializing. One moment please... Indicates that the HP 3048 is setting up the instruments
for the measurement.
LAG/LEAD... Indicates which Lag/Lead number is currently switched in during the functional
check.
Loading 11848A calibration data... CALDATALO and CALDATAHI are being retrieved from
the mass storage media.
Manipulating FFT data... The system is removing the spurs and processing the data from
the selected Result Files.
Manipulating RF data... The system is removing the spurs and processing the data from the
selected Result Files.
Marker not within defined measurement span... The Marker position for the currently
defined span in Noise Monitor Mode is outside of the Plotted Range specified in the Segment
Table.
Action: Move the Marker or select the appropriate span and press TAKE SWEEP. If the
appropriate SPAN is not available in the Segment Table, the table must be modified to include
the desired Plotted Range.
Measuring PLL suppression... When Verification of the Loop Suppression is selected, the
system locks the phase lock loop, injects noise into the loop, and then measures the response
of the loop.
