Basic Data Obtained on Zaolla Cables

These are the facts; the fundamental electrical expressions that we can extract with the test equipment.

The Microphone Cable
 
 
 

Frequency Response: The following graph is the Frequency Response of 3 meters of the cable swept from 5 Hertz to 5 megahertz at a 2.84 Volt P-P signal for a 0 dB Reference Level. The source impedance is 50 Ohms and the load impedance is 10,000 Ohms. (Remember, the range is 0.1 dB per division or 1 "cenibel," which would clearly show the smallest deviations.) 

Phase Response: The following graph shows the Phase Response of 3 meters of the cable swept from 5 Hertz to 5 megahertz at a 2.84 Volt P-P signal. The source impedance is 50 ohms and the load impedance is 10,000 ohms. The range is 1 degree per division. 

In neither case does the cable display any reactive characteristics over the 11-octave audio range of 20 to 20,000 Hertz.  As a final verification of the lack of reactive qualities in the audio pass band, note the following Smith Chart. Throughout the sweep, the signal remains at the pure simple resistance point, displaying neither capacitive nor inductive qualities, thus noting the non-reactive character of the cable as an element in a network.
