B-3 Operation Error Messages Error Messages
B-2 PN: 10580-00207 Rev. E BTS Master UG
Over Power Start FAILED
RF Power applied to the input connector is too high at turn on. See Over Power FAILED error
above.
Mixer Saturation: Increase Attenuation
or
Mixer Overdrive FAILED
Too much power applied with too little Attenuation. Increase attenuation. Sometimes even
out of band frequencies may be present that would cause a Mixer Overdrive Error. In highly
rich RF environments it may be necessary to add an external band pass filter to reduce
unwanted interference. See the accessories section for a list available band pass filters from
Anritsu. Out of band frequencies can often be detected by increasing the SPAN to maximum
in peak detect mode of operation. Another resolution may be to Reset to factory defaults with
either Factory Defaults, ESC+ON, or MASTER RESET, ON. Caution: Use of
MASTER RESET, ON, will erase all user saved setups and measurement traces and
return the unit to a fully Factory Default condition. If the error persists, contact your Anritsu
Service Center.
B-3 Operation Error Messages
ADC Over range: Increase Reference Level
Input signal is too large for the Analog to Digital converter to process. Increase the internal or
external attenuation or, if using Auto attenuation, increasing the Reference Level should
resolve the error. See also the Mixer Overdrive error above for information on Out of band RF
power.
Calibrator Reading Error
Calibration reference source is not providing quality signal. Insure that the battery level is
adequate for operation or that temperature is within acceptable limits. Reset to factory
defaults with either Factory Defaults, ESC+ON, or MASTER RESET, ON. Caution:
Use of MASTER RESET, ON, will erase all user saved setups and measurement
traces and return the unit to a fully Factory Default condition. If the error persists, contact
your Anritsu Service Center.
Fatal Error
Usually caused by a failure to communicate with one section or another. Sometimes resolved
by restarting the unit or by Factory Defaults, ESC+ON, resetting of the unit. Under extreme
cases the use of MASTER RESET, ON, may resolve the issue. Caution: Use of
MASTER RESET, ON, will erase all user saved setups and measurement traces and
return the unit to a fully Factory Default condition. If the error persists, contact your Anritsu
Service Center.
Trace not saved. Please wait for complete sweep and try again.
Attempted to save a measurement trace before the sweep had completed at least once. Wait
for at least one complete sweep and try to save again.
Measurement not valid in Zero Span
Attempt was made to make an automated measurement that requires more than ZERO
SPAN to accomplish. An example would be Occupied Bandwidth measurement.
