Message Meaning
“ERROR in FM DAC SENS: Cannot count beat frequency (3)”Thebeat frequency could not be count ed when the FM DAC was
set to 4095.
“ERROR in FM DAC SENS: Result out of range”The calculated result for this test was outside reasonable limits.
“ERROR in FREQUENCY ACCY:Cannot count YIG (1)”The 1st LO frequency could not be determi ned.
“ERROR in FREQUENCY ACCY:Out of range (1)”The result was outsideof acceptable limits.
“ERROR in FREQUENCY ACCY:Out of range (2)”The result was outsideof acceptable limits.
“SPANS:range X”This is an indi cator to show which span range is being tested. This
is not an error message.
“ERROR in SPANS:Cannot count at center screen, DAC low”For this span range, the effective screen frequency could not be
determined when the span DAC was set to 30 and the sweep was
parked at center screen.
“ERROR in SPANS:Cannot count at center screen, DAC high”For this span range, the effective screen frequency could not be
determined when the span DAC was set to 4095 and the sweep
was parked at center screen.
“ERROR in SPANS:Cannot count at right screen, DAC low”For this span range, the effective screen frequency could not be
determined when the span DAC was set to 30 and the sweep was
parked at right screen.
“ERROR in SPANS:Cannot count at right screen,DAC high”For this span range, the effecti ve screenf requencycoul d not be
determined when the span DAC was set to 4095 and the sweep
was parked at right screen.
“ERROR in SPANS:Span out of range”The calculated result for thi s test was outside reasonable limits.
“ERROR in GAIN AND ATTEN:Cannot span down on (1)”On the first attempt, the cali bratorcoul d not be centered calibrator
sufficiently to go to zero span without losing the signal.
“ERROR in GAIN AND ATTEN:Cannot span down on
calibrator(2)”
On the second attempt, the calibrator could not be centered
sufficiently to go to zero span without losing the signal.
“ERROR in GAIN AND ATTEN:Cannot calculate lin sensitivi ty”Lin mode sensitivity figures were outside reasonable mode limits.
“ERROR in GAIN AND ATTEN:Attenuation result out of range”One of the at tenuator steps measured outside reasonable limits.
“ERROR in GAIN AND ATTEN:Gain step result out of range”One of the gain steps measured outsi de reasonablelimits.
“ERROR in VR FINE GAIN: Cannot span down on calibrator”On the second attempt, the calibrator could not be centered
sufficiently to go to zero span without losing the signal.
“ERROR in VR FINE GAIN: Cannot calculate lin mode sensitivity”Lin m ode sensitivity figures were outside reasonable limits.
“ERROR in VR FINE GAIN: Result out of range”The calculated result for this test was outside reasonable limits.
“ERROR in VR FILTERAMPLTD: Cannot measure lin mode
sensitivity”
Lin mode sensitivity figures were outside reasonable limits.
“ERROR in VR FILTERAMPLTD: Cannot set filt ert o full screen”The RF attenuators could not reduce the signal below full screen.
“ERROR in VR FILTERAMPLTD: Result out of range”The calculated result for this test was outsi de reasonablelimits.
“ERROR in VR LOG FLTRAMPLTD: Cannot set filter to f ull
screen”
The RF attenuation, VR gain, and VR fine gain together could not
set the filter being tested to full screen.
“ERROR in VR LOG FLTRAMPLTD: Result out of range”The calculated result for this test was outside reasonable limits.
