T e s t s & M e a s u r e m e n t s

Over twenty five years of manufacturing, research and engineering have led KIMBER KABLE

to explore in great detail the physical and electrical properties that influence signals and the

correlation to sensory quality. Through our OSCaR™ (objective Subjective, Correlation and

Results) engineering process KIMBER KABLE has developed many new proprietary proce-

dures for testing, engineering, manufacturing and evaluating cable. This process has allowed

us to make the vital link between scientific measurements and listening impressions.

The following precision laboratory test instruments are owned and operated in-house by KIMBER KABLE:

Yokogawa PZ4000 Power Analyzer

Klippel Analyzer System w/all modules and Laser Displacement meter

JTF Analysis System (Similar to HP 3587 except with higher 96/24 resolution)

Agilent 54624A 2 Mb Memory Mega Zoom Oscilloscope

CLIO Electro-Acoustic Analyzer

PC 80 Phase Checker, Sencore PR 57, Sencore LC53, Leader LCR-740, Morrell MI-10, Meiji EMZ-TR Microscope.

For production testing and quality assurance we use the following basic parameters:

Rdc: (resistance) basic dc resistance.

X:(reactance) ac resistance due to the capacitance and inductance of the cable; a frequency dependent property.

Xc: capacitive reactance.

Xl: inductive reactance.

Z:(impedance) total electrical opposition due to both ac reactance and dc resistance; a frequency dependent property.

Cp:

C:ability to store energy in electrostatic fields. Cp: parallel aspect of capacitance.

Ls:

L:ability to store energy in magnetic fields. Ls: series inductance.

Gain / Phase testing:

Gain (the increase or loss of signal) and Phase test for the cables variances caused by the C, L, R and other numerous properties of the cable system.

Crosstalk testing:

Conductors were separated at the amplifier end.

These test parameters are used for production testing and in-house comparisons. Other extensive tests such as: RF broad band tests, T/R gain/phase, R/T-GAMA, R/T-THETA, S-PARAMETERS, etc. are used in research diagnostics. Our research diagnostics further includes listening evaluation. Correlations between sensory and electrical measurements are proprietary.
