Obtaining Cable Correction Data

Obtaining Cable Correction Data
The procedure to obtain cable correction is described below.
Step 1. Press [System].
Step 2. Press the CABLE CORR softkey.
In Option 002, the CABLE CORR softkey is not available on the SYSTEM
INFO page.
Step 3. Use the cursor keys to select from cable length of 1m or 2m.
Step 4. Connect a 100 pF capacitor (16383A) or 1 kΩ resistor (42037A) to the
UNKNOWN terminals.
Step 5. Press the MEAS REF softkey. The data for the reference correction is then
measured.

Step 6. Remove the standard capacitor/resistor from UNKNOWN terminals. Connect
the cable length of 1 m or 2 m.
Step 7. Connect the OPEN termination 42090A at the end of cable.
Step 8. Press the MEAS OPEN softkey. The data for the OPEN correction is then
measured.

Step 9. Remove the OPEN termination and connect LOAD standard 16383A (100 pF)
or 42037A (1 kΩ) to the end terminal of the cable.
Step 10. Press the MEAS LOAD softkey. The data for the LOAD correction is then
measured.
