3-1. INTRODUCTION

This section provides the information necessary to use the 41941A/B.
and Notes are given throughout, and they should be followed to insure operator
TIONS,
safety and servicaebility of the unit.
For detailed information on 4194A operation, refer to the
Manual .

has two compensation methods, calibration and offset. Calibration compensates

for measurement errors caused by the measurement instrument and the probe. Offset com­
pensates for measurement errors caused by residual impedance and stray admittance be­
tween the calibration plane and the

3-2-1. Calibration

Calibration is required to compensate for measurement errors due to the frequency charac­
teristics of the probe. When the probe is calibrated using the supplied calibration standards,
the calibration plane of the probe extends to the fringe of the pin's top plane as shown in
Figure 3-1. The calibration plane is the point at which impedance can be correctly
measured.
