QT8200

Qmax QT8200 - 8 MHz Mixed Signal In-Circuit Functional Tester

High Speed Mixed Signal In-Circuit Functional Tester to test all types of Digital, Analog & Mixed devices like TTL, CMOS, ECL, PECL, EIA and the latest 3.3V Logic devices.

Qmax’s QT8200 is setting the standards in In-Circuit Functional PCB Test and Diagnostic systems. It comes with a complete range of functions that are required for improved faults coverage of almost any type of boards. Its powerful digital and analog in-circuit power on functional test is most useful in troubleshooting faulty PCBs that are populated with mixed signal devices. It can test devices such as Op-amps, ADCs, DACs, Comparators etc., functionally under power-on condition by driving the inputs with a complete test pattern and calculating the expected outputs using its powerful evalution engine. In-Circuit Device Under Test (DUT) pin interconnects are automatically taken care of by the software. Users need only to key in the number of the DUT and QT8200 will automatically test and provide a clear PASS or FAIL result. It provides a complete waveform display for failure confirmation.
QT8200 provides the user with a Learn/Compare function that allows the user to learn the DUT interconnect and test status. This information is used during Test Comparison to enable the user to detect illegal open, shorts or wrong impedance on the DUT. This is most helpful since circuit diagrams are not usually available while testing the faulty PCBs. The powerful Graphical Test Program Generation function allows the user to generate functional tests for PALS, ROM and many unknown LSI / VLSI ICs. Circuit Tracer Function allows the user to trace the circuit of a PCB and use a CAD software to generate the schematic for documentation purpose or for reverse engineering.
QT8200 also comes with the QSM or Super V-I Technique. It is a very innovative signature method that is developed by Qmax and can be used as a general or universal test method. It is very effective on boards populated with ASICs and unknown VLSI ICs and can be used as a QA tool. QSM can detect DUT shorts, opens between any pins and functional failures up to a very high degree using its unique signature method and without the need to write complicated test program. QSM provides more fault coverage than simple in-circuit component value measurement or the fixed reference VI.
