Impedance Box
-
An impedance box is necessary for measuring the impedance of a loudspeaker. Listen Inc.’s impedance box contains a 0.25Ω resistance. This value is suitable for most loudspeakers, but may be easily swapped out for a different value by the user if speakers with a particularly high or low impedance are being tested. It is available with either XLR or 1/4″ balanced connectors. Please specify type of connectors when ordering.

12C
-
A high speed, high input impedance active probe for measuring the internal node voltage of integrated circuits. The input is 1 megohm shunted by 0.1 pf and the rise/fall times are 0.8 ns. This instrument has full dc capability and can be used with any oscilloscope. The Model 12C was specially designed so that when used in conjunction with a high input impedance oscilloscope, signal attenuation is 10:1 and with a 50 Ohm input, signal attenuation is 20:1.

Localized Electrochemical Impedance Spectroscopy
VS-LEIS
-
The VersaSTAT 3F applies an AC voltage to the sample emerged in electrolyte. This "global" voltage generates AC current to flow at the electrode / electrolyte interface. A dual-element probe is positioned in solution close to the surface of the sample. The electrometer measures a differential voltage measure between the two measurement elements as a measure of local voltage-drop in solution. This voltage-drop exists in solution because of current flow from local reactions at the sample, the resistance of the electrolyte and the spatial separation of the dual measurement elements.
