Huntron® Trackers® utilize the power off testing methodology of Tracker Signature Analysis. The development of the Huntron ProTrack® I has taken power off troubleshooting to a new level.Huntron® Tracker® Signature AnalysisA current-limited AC signal is applied across two points of an electronic component or circuit. The resulting current/voltage waveform is displayed on a CRT using vertical deflection for current and horizontal deflection for voltage giving a unique signature that represents the overall “health” of the DUT (device under test).Basic Tracker SignaturesTracker signatures can be categorized into four basic types based on four basic component types. These signatures are resistive, capacitive, inductive and semiconductive signatures. All signatures will exhibit at least one of these characteristics but more often include combinations that are referred to as composite signatures. Resistive signatures have a linear response with the angle of the trace determined by the value of resistance. Capacitive signatures have an elliptical response with the width of the trace determined by the value of capacitance. Inductive signatures have an elliptical response. The trace width is determined by the value and the angle by component resistance. Inductors often exhibit a distorted shape. Semiconductive signatures show the conducting and nonconducting states. Approximate breakover voltages can be determined using the horizontal graticule. Getting Down to BasicsComparing Tracker signatures can be accomplished manually or with the aid of a computer for signature storage using the Huntron Workstation for Windows® software. All Huntron Trackers utilize dual channel interfaces for easy side-by-side comparison of good versus suspect circuit boards. Using this comparison method, suspect components can be quickly identified.Looking for DifferencesTroubleshooting with Tracker signatures is possible without the use of documentation or known good circuit boards. This is accomplished by searching for patterns in the signatures that are displayed on like pins of a component or bus.An example would be to compare all of the input pins on an inverter IC with each other and compare all of the output pins of the inverter with each other looking for variances in the signature patterns. The input and output pins should compare favorably with similar pins. Any deviations in the pattern could indicate a real problem. This same technique can be applied to address and data bus lines and circuit boards that have duplicated circuitry such as multi-channel boards.The Huntron ProTrack IThe ProTrack I Model 20 enables the user to set the applied voltage, frequency and source resistance to best match the circuit characteristics and display the optimum Tracker signature. Connecting to a personal computer will allow for creation of complete test routines and signature storage.The Value of Variable Test Ranges (V + R + F)Three variables make up a Tracker test range: voltage (V), internal Tracker resistance (R) and AC sinewave frequency (F). By adjusting any of these three variables, either individually or in combination, characteristics of the Tracker signature can changed. The examples below show a simple circuit made up of a diode, resistor and capacitor in parallel. Note how the Tracker range parameters are varied to bring different aspects of the signature into focus.Using the Huntron ProTrack Pulse GeneratorThe Huntron ProTrack I has a built-in pulse generator for triggering gate-fired devices such as SCRs (silicon controlled rectifiers), TRIACs, optocouplers and relays. By driving the control input of the device under test while using the ProTrack I to monitor the signature of the outputs, a dynamic test of the component can be performed. Gate-fired components can effectively be turned on and off to check their functionality.The gate output of the pulse generator is connected to the gate of the device. The device output terminals are connected to the ProTrack I test and common leads. The pulse generator voltage is then increased until the device turns on. The example below shows the off and on state of a common SCR.The pulse generator can apply either a DC voltage or a pulsed square wave to the gate-fired device. The amplitude is variable and can be controlled manually or using the Huntron Workstation for Windows software.Specifications: Electrical Open Circuit Voltage (Vs: 24 selections of peak voltage): 200mV, 400mV, 600mV, 800mV 1V to 20V in 1V steps including 10V (Low), 15V (Med 1), 20V (Med 2) Source Resistance (Rs: 16 selections of resistance): 10Ω, 20Ω, 50Ω, 100Ω, 200Ω, 500Ω, 1kΩ, 2kΩ, 5kΩ, 10kΩ, 20kΩ, 50kΩ, 100kΩ, 54Ω (Low), 1.2kΩ (Med 1), 26.7kΩ (Med 2) Maximum Current: 200 mApk (Vs/Rs; short circuit current) Frequency (Fs: 36 selections of frequency): 20Hz to 190Hz in 10Hz steps 200Hz to 1.9kHz in 100Hz steps 2kHz to 5kHz in 1kHz steps Channels Number 2 Display modes A, B, Alt, A+B Overvoltage Protection Circuit breaker Pulse Generator Level 0 to ±10V Width (pulse mode) 2% to 50% duty cycle Source resistance 100Ω Short circuit current 100mA max Displays CRT monochrome, 2.8" (7cm) diagonal LCD full graphic, 128 x 64 pixels Power Requirements Line Voltage/Freq. 90VAC to 250VAC / 47Hz to 63Hz Power 30W Dimensions 11.6” W x 4.5” H x 15” D (30cm W x 11.5cm H x 38cm D) Weight 10 lbs.
