QT200

 
QT-200 Mixed Signal Functional Test System is a proven model being used by thousands of users world over for varied Test & Reapplications. QT-200 can effectively test Digital, Analog and Mixed Signal Devices in Out of Circuit and In-Circuit in as wired condition and gives clear PASS-FAIL results. It covers all logic families within +/-12v logic levels including ECL, EIA, 3.3V etc. Hybrids, ASICs and unknown devices can be checked using QSM signature method. Optional IDDE software makes new device test program generation easy with graphical user interface. Edge Functional Test with Guided probe back tracking is supported for up to 96 Test pins. QSM VI channels are available from 48 channels to 256 maximum.

QT200 is a Desk-Top Entry Level In-Circuit Functional Tester for Test & Repair of populated PCBs. It is capable of testing any 5V Logic device functionally in as wired in-circuit condition using vast Qmax device library. No matter, what in-circuit configuration of the device under test is, Qmaxs innovative auto compensation technique modifies the test vector to suit the device configuration on the fly. QT200 uses the back-driving or node-forcing technique to functionally test devices in-circuit. The in-built Auto Guarding Guide helps user to isolate those bus devices that could potentially interfere with the Bus Device Under Test. This is also extended to OC / OE devices with wired-OR function.

QT200 also offers QSM VI (Qmax Signature Method - VI) technique to test custom devices on board that cannot be functionally tested due to lack of information on the functionality. QSM VI helps to detect ESD induced failures and also enhances fault coverage using Moving Reference technique.

The Board Learn mode is used to learn the devices functionality and clip status / link information from a Known Good Board (KGB) and is stored for future reference. A faulty board of identical type can be compared with the learnt board under Board Test.

QT200 provides the facility to create a visual board layout on the screen.

QT200 can be interfaced to any PC with Windows-XP (or higher version) Operating System using USB 2.0.
