Error Messages
An error message is displayed against a red background in the instrument message/warning
area in the lower-left part of the screen. Touching Entry Off key at the front panel or
executing the :DISPlay:MESSage:CLEar command clears the error message.
Moreover, about a specific error message, when a sweep is started again, the display of an
error message may disappear. Errors caused by operation of a front panel key simply
appear on the display; with a few exceptions, these are not stored in the error queue.
The log of an error message,a maximum of 100 pieces are recorded, and it can go back and
check from the newest error. The following procedures perform the procedure of
elimination of an error check and an error log. This operation can be performed only from
a front panel. It cannot be operated by the "SCPI" command.

An error with a positive error number is one uniquely defined for this instrument. On the
other hand, an error with a negative error number is basically one defined for common
GPIB devices in IEEE488.2

120 AFC Failed
This error message appears when the Automatic frequency control function could not
follow the fluctuation in the measurement condition or automatic frequency control
function was set on, however, the power or control voltage is not being applied to the DUT
For the corrective actions, refer to the error message “AFC out of loop” and the warning
message “DC output on required in AFC”.
330 AFC out of loop
The Automatic frequency control function could not follow the fluctuation in the
measurement condition, and did not converge on the target frequency. Possible problems
and corrective action are shown below.
• Press -
Auto Freq Control - Sensitivity to specify a proper tuning
sensitivity.
• Press -
Auto Freq Control - Max Iteration to specify a value larger than the
current setting.
• Press -
Auto Freq Control - Max Ctrl Voltage Limit to specify a maximum
value larger then the current setting. Be careful not to set a value that exceeds the
DUT’s maximum acceptable value.
• Press -
DC control Delay to specify a value larger than the current setting.
