Fixture Compensation

Next, you need to eliminate errors produced between the test fixture and the Agilent
4294A. This process is called "fixture compensation." You can perform the process using
three compensation functions: OPEN, SHORT, and LOAD.
NOTE
All calibration settings, including those established through fixture compensation, are
applied to both Traces A and B. You can execute each compensation function without
specifying the active trace or checking the current state.

Perform Fixture Compensation for the Open Circuit State

Step 1. Press the
Step 2. Press the
Step 3. Make sure that the two test electrodes, HIGH and LOW, of the connected text fixture
(Agilent 16047E) are open. Be sure to fix the two electrodes in position by turning
clockwise the fixture's two electrode fastening screws.
Step 4. Press the
measuring the compensation data, a message "WAIT--MEASURING STANDARD" is
displayed in the Parameter Setting field in the upper-left area of the screen. Upon
completion of measurement, the
indicating that the OPEN compensation function is turned on.

Perform Fixture Compensation for the Short Circuit State

Step 1. Remove the short bar (a metal plate for SHORT compensation) from the upper part of the
Agilent 16047E by loosing the screws and then fit the short bar between the HIGH and
LOW terminals of the Agilent 16047E. Secure the short bar with the two electrode
fastening screws (Figure 2-3 on page 36).
