Table 6- 2: Cal Debug Messages and Meanings (Cont.)
Message Meaning
“ERROR in FM DAC SENS: Cannot count beat frequency (3)” The beat frequency could not be counted 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 determined.
“ERROR in FREQUENCY ACCY: Out of range (1)” The result was outside of acceptable limits.
“ERROR in FREQUENCY ACCY: Out of range (2)” The result was outside of acceptable limits.
“SPANS: range X” This is an indicator 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, t he effective screen frequency could 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 this test was outside reasonable limits.
“ERROR in GAIN AND ATTEN: Cannot span down on (1)” On the first attempt, the calibrator could 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 sensitivity” Lin m ode sensitivity figures were outside reasonable mode limits.
“ERROR in GAIN AND ATTEN: Attenuation result out of range” One of t he attenuator steps measured outside reasonable limits.
“ERROR in GAIN AND ATTEN: Gain step result out of range” One of the gain steps measured outside reasonable limits.
“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 mode sensitivity f igures 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 FILTER AMPLTD: Cannot measure lin mode
sensitivity”
Lin mode sensitivity figures were outside reasonable limits.
“ERROR in VR FILTER AMPLTD: Cannot set filter to full screen” The RF attenuators could not reduce the signal below full screen.
“ERROR in VR FILTER AMPLTD: Result out of range” The calculated result for this test was outside reasonable limits.
“ERROR in VR LOG FLTR AMPLTD: Cannot set filter to full
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 FLTR AMPLTD: Result out of range” The calculated result for this test was outside reasonable limits.
