• During the measurement, the ABORT softkey is shown. Use this key when
you want to abort open correction
Step 10. Repeat
Step 3 to Step 9 until you have specified all of your desired
measurement points.
Step 11. Move the cursor into the OPEN field.
Step 12. Press the ON key to enable the open correction feature.
The E4980A/AL do not have a functionality to check whether the OPEN
correction data is valid or not. Any OPEN correction data can be set, even
if work-related mistakes are made in measuring for the OPEN correction.
For example,
- improper OPEN is used.
- setting up the OPEN state and SHORT state inversely.
- the OPEN 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 OPEN correction data is invalid, it may cause inappropriate
measurements without showing warning message. Be careful about the
connection of appropriate OPEN state. OPEN A and OPEN B are measured
values when the OPEN correction is performed. You can check the
measured values.
If "E43 Measurement failed" error is displayed during the OPEN correction,
measure the OPEN state (disable OPEN correction[OPEN 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)
