Warning Message
A warning message is dispalyed in the instrument status display area in the
lower-left part of the display. Pressing any of the front panel keys or executing
the :DISP:CCL command clears the message.
This message simply appears on the display since it is not known to remote
environments such as GPIB. This message is not displayed when another error
message has been already displayed in the instrument message/warning area.
The warning messages for this instrument are as follows.

2 I bias units

ALC unable to regulate
The voltage level setting is inappropriate for using the ALC function. The ALC
function does not work and the operation will be the same as when the ALC
function is turned off. The measurement data status is set to 4. Refer to
E4980A/ E4980AL User's Guide.
C
Clear the table first
This error occurs when the value of MODE has been changed when the LIMIT
TABLE SETUP screen is moved to another screen or the sweep parameter on
the LIST SWEEP SETUP screen is changed even though a sweep list for
another measurement parameter exists. Clear the table first.
Correction, not effective
The correction function does not work because the MULTI correction mode is
used but the test frequency is not equal to the spot frequency.
I
Improper high/low limits
The upper limit value is less than the lower limit value. Set the lower limit value
to less than the upper limit value.
