Pim Analyzer Warning Messages - Anritsu PIM Master MW82119A Maintenance Manual

3-3 PIM Analyzer Warning Messages

4. Main PCB has failed. Replace the Main PCB assembly.
Unit makes normal boot-up sounds, but the display has a problem:
1. If the display is dim, then check the brightness setting under the System Menu / System Options.
2. Replace the LCD assembly.
3. The Main PCB has failed. Replace the Main PCB assembly.
Boot-up Self Test fails:
1. Perform a Master Reset. Be advised that a Master Reset will delete all user saved setups, JPEG, and
measurement files. Ensure that you have backups of these before performing a Master Reset.
2. If the message relates to the RTC battery, then replace the Main PCB.
3. The Main PCB has failed. Replace the Main PCB assembly
3-3 PIM Analyzer Warning Messages
Instrument powers up, but displays a warning message:
1. Ref PLL Lock Error or RF PLL Lock Error
These indicate a potential hardware failure that could compromise measurements. If the failure persists,
then contact your Anritsu Service Center.
2. EMERGENCY Shut Down switch pressed
The PIM Master front panel EMERGENCY STOP button has been pressed. This will turn off the PIM
RF power output, and measurements may be invalid. If the condition persists, then contact your Anritsu
Service Center.
3. PIM AMP(S) Exceeding Normal Temperature Range
The internal PIM Master amplifiers have exceeded their normal operating temperature. This could
indicate a potential hardware failure that could compromise measurements. If the failure persists, then
contact your Anritsu Service Center.
4. PIM UNIT Exceeding Normal Temperature Range
The entire PIM Master instrument is beyond its normal operating temperature. This could lead to a
potential degradation in measurements, and signal dropout could occur. If the failure persists, then
contact your Anritsu Service Center.
5. PIM EEPROM Error
The PIM Master cannot access its on-board EEPROM. This could indicate a potential hardware failure
that could compromise measurements. If the failure persists, then contact your Anritsu Service Center.
6. 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.
This message is displayed in PIM vs Time and Swept PIM measurement modes if PIM values exceed this
saturation limit.
7. Receiver Amplitude Low
This message can occur if signal amplitude degrades within the instrument. It can have an impact on
overall measurement accuracy and should be an indicator to sent the unit to Anritsu Service Center for
repair.
