Next, you need to eliminate errors produced between the test fixture and
the E4990A. This process is called “fixture compensation.” You can perform
the process by using three compensation functions: OPEN, SHORT, and
LOAD.
All calibration settings, including those established
through fixture compensation, are applied to both Traces 1 and
2. You can execute each compensation function without
specifying the active trace or checking the current state.
Perform Fixture Compensation for the Open Circuit State
1. Press the Cal key to display the Cal Compen (Calibration
Compensation) menu.
2. Press the Fixture Compen softkey to display the Fixture Compen
(Fixture Compensation) menu.
3. Ensure that the two test electrodes, HIGH and LOW, of the connected
