The Tracker has the ability to vary the output AC voltage level. Listed below are th available settings. the ilbl tti Tracker Voltage ranges (24 selections of peak voltage): 200mV-800mV in 200mV steps, 1V-20V in 1V steps
Page 5
Tracker Frequency (Fs) Ranges (36 selections): 20Hz.-190Hz. in 10Hz. steps, 200Hz.-1.9KHz. in 100Hz. steps, 2KHz-5KHz in 1KHz. Steps

Tracker Resistance (Rs) Ranges (16 selections of resistance): 54 ohms (low), 1.2 Kohms (Med 1), 24 Kohms (Med 2), 74 Kohms (high),10 ohms, 20 ohms, 50 ohms, 100 ohms, 200 ohms, 500 ohms, 1Kohm, 2Kohms, 5Kohms, 10Kohms, 20Kohms, 50Kohms, 100Kohms

There are only four basic electronic properties that the Tracker displays: resistance, capacitance, i d t i t it inductance and semi-conductance. E hof these d i d t Each f th behaves differently as the sine wave is applied, so each shows a different signature on the display. Because of the uniqueness of the display, created by each of the different electronic properties, these displays are referred to as signatures. Circuits that have more than one type of component in them, have signatures that are composites of the elements in that circuit.All signatures will be one of the four or a composite made up of two or more of the four For example a circuit with both resistance and capacitance will four. example, have a signature that mixes the characteristic signatures of resistance and capacitance. Resistance is always indicated by an angle. Capacitance will be a circle or ellipse pattern. Inductance will also be a circle or ellipse,probably distorted by internal resistance or inductive action. Last, there is the diode junction that forms an angle or “knee”.

Theshape of inductive signatures can be somewhat distorted depending on the th construction of th d i t ti f the device. C Core t type such as solid or layered (l i t d) h lid l d (laminated) will affect the amount of distortion observed in the signature.

Zener diode signatures are sometimes referred to as “chair” signatures because of th i shape. b f their h The zener signature is the most common style of signature observed when testing digital electronic circuits. This is mainly due the protection circuitry built intodigital Ics.
