• During the measurement, the ABORT softkey is shown. Use this key when
you want to abort short correction.
Step 6. Press the ON key to enable short correction in successive measurements.
Description of the Softkeys
To enable/disable or otherwise control the behavior of short correction, use the
following softkeys:
The E4980A/AL do not have a functionality to check whether the SHORT
correction data is valid or not. Any SHORT correction data can be set, even
if work-related mistakes are made in measuring for the SHORT correction.
For example,
- improper SHORT is used.
- setting up the OPEN state and SHORT state inversely.
- the SHORT 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 SHORT correction data is invalid, it may cause inappropriate
measurements without showing warning message. Be careful about the
connection of appropriate SHORT state. You cannot check the measured
values for the SHORT correction.
If "E43 Measurement failed" error is displayed during the SHORT
correction, measure the SHORT state (disable SHORT correction[SHORT
OFF]) at some frequencies (100, 1k, 1MHz etc.) 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)
