either Factory Defaults, ESC+ON, or MASTER RESET, System+ON. Caution: Use of
MASTER RESET, System+ON, will erase all user saved setups and measurement traces and
return the unit to a fully Factory Default condition. If the error persists, then contact your
Anritsu Service Center.
Overall Status FAILED
One or more elements of the System or Application Self Test has failed. Refer to the other
pass fail tests listed below to determine which specific test failed.
Over Power FAILED
RF Power applied to the input connector is too high. Remove or reduce the input power or add
additional attenuation. Sometimes out of band frequencies may be present that can cause an
Over Power 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 of
available band pass filters from Anritsu. Out of band frequencies can often be detected by
increasing the Span to maximum in the peak detect mode of operation. Another resolution
may be to reset to factory defaults with either Factory Defaults, ESC+ON, or MASTER
RESET, System+ON. Caution: Use of MASTER RESET, System+ON, will erase all user
saved setups and measurement traces and return the unit to a fully Factory Default
condition. If the error persists, then contact your Anritsu Service Center.
Over Power Start FAILED
RF Power applied to the input connector is too high at turn on. See Over Power FAILED error
above.
