• During the measurement, the ABORT softkey is shown. Use this key when
you want to abort load correction
Step 15. Repeat
Step 3 to Step 14 until you have specified all of your desired
measurement points.
Step 16. Move the cursor into the LOAD field.
Step 17. Press the ON key to enable the load correction feature.
The E4980A/AL do not have a functionality to check whether the LOAD
correction data is valid or not. Any LOAD correction data can be set, even if
work-related mistakes are made in measuring for the LOAD correction.
For example,
- improper LOAD is used.
- setting up the OPEN/SHORT state and LOAD state inversely.
- the LOAD is connected incompletely.
- fixture or cable is connected incompletely.
- previous correction data is used.
- after correction, different length cable/different fixture is connected or
settings of frequency/level is changed.
If LOAD correction data is invalid, it may cause inappropriate
measurements without showing warning message. Be careful about the
connection of appropriate LOAD state. LOAD A and LOAD B are measured
values when the LOAD correction is performed. You can check the
measured values.
If "E43 Measurement failed" error is displayed during the LOAD correction,
measure the LOAD state (disable LOAD correction[LOAD OFF]) at
frequency you select and check if the following conditions happen. If one
of them happens, try its suggestion.
"ALC unable to regulate" warning message is displayed (suggestion: turn
off ALC)
"Signal source overload" warning message is displayed (suggestion:
reduce test signal)
"Overload" is displayed (Measurement result becomes overload)
(suggestion: check cabling/fixturing)
