6.1 Error Messages 

FRA5022 

6-2 

6.1 

   

Error Messages 

Self-diagnosis is performed when the power is turned on. If an error is detected, an error 
message is displayed in the lower part of the start screen. Similarly, when improper 
values are being set via the remote control interface, an error message is displayed. Error 
messages are also displayed when your operation via the front panel has some 
restrictions. 
Error messages and their causes are described below, together with required actions. 
Some other messages may be displayed depending on the situation. 

 

6.1.1  Errors at Power-On 

Error messages 

Cause 

Required action 

ROM ERROR 

Internal ROM error 

Turn the power off, wait for at 
least 3 seconds and turn the 
power on again. If the error 
message persists after turning 
the power on several times, it 
will be necessary to make 
repairs. Contact NF 
Corporation or one of our 
representatives. 

SDRAM ERROR 

Internal SDRAM error 

BACKUP MEMORY 
  ERROR 

Battery backup contents are 
broken. 

・

Backup battery is empty 

・

Backup memory fault 

・

Temporary internal data error 
due to power-off, etc. while 
operating on the memory 

ANALYZER ERROR

 

Analyzer malfunction 

CALIBLATION 
ERROR

 

Self calibration error 
Problem with the signal 
measurement system in the 
oscillator or the analyzer. 

 

When an error message is displayed, check 

“Installation Conditions”

 in 

“2.2 Installation”

 and 

verify that all the operation conditions are met. 
When ROM or SDRAM error is detected, further operation is not possible. 
When battery backup contents are broken, the device starts after settings and 
measurement data memory are initialized. When that happens, the line after the above 
error message indicates which memory category has been initialized. 
 

STn: 

Settings memory n = 0..9

 

NS: 

Settings not indicated on the left

 

SA: 

Data memory A for sweep measurements

  SB: 

Data memory B for sweep measurements

 

PA: 

Data memory A for spot measurements

 

PB: 

Data memory B for spot measurements

 

 
When signal system error during analyzer self check or self calibration is found, error 
messages are displayed and further operation is not possible.
