Figure 4-11. OPEN/SHORT Correction Using The Interpolation Method
Front Panel Operation for the Open Correction
There are two pro cedures: OPEN correction using the interpolation
metho d, and OPEN correction at the frequency poin
ts you sp ecify.
Perform the following steps to execute the OPEN correction at all
frequency points using the interpolation metho d. When you wantto
execute the OPEN correction at a single frequency p oin
t, refer to
\LOAD Correction".
1. Move the cursor to the OPEN eld. The following softkeys will b e
displayed.

2. Connect your test xture to the UNKNOWN Terminals without
connecting the device under test.

MEAS OPEN . The HP 4284A will measure the OPEN
admittance (capacitance, and inductance) at the preset frequency
points. The time required to measure the op en correction data is
approximately 90 s. During the OPEN correction measurement,
the following softkey is available.
NNNNNNNNNNNNNNNNN
ABORT
This softkey is used to stop an OPEN correction data
measurement. The previous OPEN correction data will still b e
stored.
