Executing measurement to compensate errors

You can compensate for errors in the measurement caused by disturbances
such as stray admittance and residual impedance of the test fixture and cable.
Corrections should be performed before actually connecting the DUT to the
test fixture.
Measuring data for OPEN correction
The OPEN correction is provided to remove stray admittance parallel to the
DUT. The procedure to measure the data for OPEN correction is described
below.
Step 1. Press the [Meas Setup] key.
Step 2. Press the CORRECTION softkey. The CORRECTION display page as shown in
Figure 3-8

Step 3. Use the cursor keys to select the OPEN field.
Step 4. Connect the UNKNOWN terminal and the test fixture with no DUT connected.
Step 5. Press the MEAS OPEN softkey. The data for the OPEN correction is then
measured.

During the measurement, an "OPEN measurement in progress" message is
shown on the display.
When the measurement has finished, the "OPEN measurement in progress"
message disappears.
During the measurement, the ABORT softkey is shown. Use this key when
you want to abort open correction.
