Measurement Accuracy

The measurement accuracy includes stability, temperature coefﬁcient, linearity,

repeatability, and calibration interpolation error. The measurement accuracy is speciﬁed

when all of the following conditions are satisﬁed:

–

Warm-up time: ≥ 30 minutes

Test cable length: 0 m, 1 m (Keysight 16048A), or 2 m (Keysight 16048D). For the 1 m

or 2 m cable length operation (with Keysight 16048A/D), CABLE CORRECTION has

been performed

–

OPEN and SHORT corrections have been performed.

The optimum measurement range is selected by matching the DUT’s impedance to the

effective measuring range shown in Figure 1-1 and Figure 1-2. (For example, if the

DUT’s impedance is 3 kΩ and oscillator level is less than or equal to 1 V, the optimum

range is the 500 Ω range.)

–

Measurement accuracy is speciﬁed at the following reference planes:

– Test frequency ≤ 1 MHz

At the UNKNOWN terminals on the Keysight 4285A front panel or at the end of the

standard test leads (Keysight 16048A/D).

– Test frequency ≥ 1.001 MHz

At the 1-port terminal of the Keysight 16085B Terminal Adapter, which should be

connected to the UNKNOWN terminals of the Keysight 4285A or to the end of the

standard test leads (Keysight 16048A/D).

|Z|, |Y|, L, C, R, X, G, and B accuracy

|Z|, |Y|, L, C, R, X, G, and B accuracy A_eis given as

A_e= ±(A_n+ A_c) K_t[%]

where:

A_n= Basic accuracy equation given from the A₁to A₁₆shown in Table 1-1. The applicable

frequency range and impedance range of equations A₁to A₁₆are shown in

Figure 1-3 and Figure 1-4. (Refer to Basic Accuracy Equations on page 7.)

A_c= Cable length factor (Refer to Cable Length Factor on page 10.)

K_t= Temperature factor (Refer to Temperature Factor on page 10.)

L, C, X, and B accuracies apply when D_x(measured D value) ≤ 0.1.

When D_x> 0.1, multiply A_eby 1 + D²_xfor L, C, X, and B accuracies.

R and G accuracies apply when Q_x(measured Q value) ≤ 0.1.

When Q_x> 0.1, multiply Ae by 1 + Q²_xfor R and G accuracies. G accuracy given by the

equation above applies to the G-B combination only.
