Performing OPEN
Correction
To perform an OPEN correction data measurement, set up an OPEN
condition, nothing is connected to the test xture. When the OPEN
measurement is being performed, don't touchormoveyour hands
near the test xture.
Performing SHORT
Correction
To perform a SHORT correction data measurement, set up a SHORT
condition, using a shorting bar to short b etween high terminal and
low terminal of the
UNKNOWN
terminals.
Figure 6-15 shows a sample shorting bar (HP Part Number
5000-4226) for the HP 16047A/C/D test xtures.
Figure 6-15. Sample Shorting Plate
The shorting bar should havevery low residual imp edance, so a high
conductivity metal plate that is not easily corro ded, is recommended
for the shorting plate. (It must b e clean.)
