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.
Suggestions:
Clear the table first and then change the Limit mode.
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. Or the lower limit value
is larger than the upper limit value.
Suggestions:
Set the lower limit value to less than the upper limit value. Or set the upper
limit value to larger than the lower limit value.
Incompatible state file
The setting file recalled from a USB memory device has been saved using an
E4980A/AL with a different firmware version or different options. There may be
some parameters set up incorrectly. This message may appear when the
connection status of the 42841A is different from the one when it has been
saved.
Suggestions:
Check the firmware revision and options of the setting file.
S
Signal source overload
The test signal current exceeds a value shown in Table 11-6. The measurement
data is not guaranteed to be valid. The measurement result data status of the
measurement result output is set to 3.
Suggestions:
Reduce the test signal level so that the test signal current doesn’t exceed a
value shown in Table 11-6.
