Warning messages provide information but allow measurements to continue.
RF PLL Lock Error REF PLL Lock Error
These indicate a potential hardware failure that could compromise measurements. If the failure persists, please contact your Anritsu Service Center.
EMERGENCY Shut Down switch pressed!
PIM front panel EMERGENCY STOP button has been pressed. This will turn off the PIM RF. Measurement results may be invalid.
PIM AMP(S) Exceeding Normal Temperature Range
The PIM Master internal amplifiers have exceeded their normal temperature range.
PIM UNIT Exceeding Normal Temperature Range
The entire PIM Master unit is beyond the normal temperature range and degradation in measurement or signal dropout can occur.
PIM EEPROM Error
Can not access on‑board EEPROM. Measurement results may be invalid.
IM OVERLOAD
This is a warning message that the measured signal level is approaching the saturation limit of the instrument. The actual signal level may be higher than the reported signal level under this condition. IM Overload is displayed in PIM vs. Time and Swept PIM measurement modes if PIM values exceed this saturation limit.
