DETAILED ACCURACY SPECIFICATION GUIDE
CONDITIONS
The following conditions must be met for the unit to meet its accuracy specifications
1) Warm up time: > 30 minutes
2) Temperature: 23 ± 5 °C
3) Fixture: Built in
4) Open & Short Circuit Calibration have been performed
5) D < 0.1 for Capacitance Measurements
Q < 0.1 for Resistance Measurements
Q > 10 for Inductance Measurements
ACCURACY EQUATIONS
The accuracy of a measurement is a function of the basic accuracy at that frequency, measurement rate, the
signal amplitude, and where the impedance of the DUT is within the measurement range. The basic accuracy
can be determined from the impedance graph or from the individual parametric graphs. Additional factors are
determined by the measurement conditions and the impedance of the DUT. From these, the accuracy of a
measurement in its optimal range can be calculated. See the following section for effects due to
measurements made out of an optimal range.
