Qmax QT200 - Best PCB Repair & Diagnostics System

In-Circuit Functional Tester with TTL, CMOS, ECL, EIA and 3.3V Logic for PCB

FEATURES

• Standard test library for TTL, CMOS, ECL, EIA, 3.3V, LSI, 12V Logic
  families and linear devices
• Power ON true digital and analog functional testing in-circuit and
  out-circuit
• Automatic Pass / Fail analysis for the device under test
• Unknown device idenification to findout unmarked devices
• Loop test to isolate intermittently failing devices
• In-circuit resistance and capacitance measurement
• Automatic pull-up and pull-down resistors for multi-block device testing
• Powerful Waveform Display for comparision with the evaluation engine and the output
• Versatile Clipstaus Display with voltage / dynamic impedance / label display
• Comprehensive Data Display on demand for the device under test
• Powerful board learning and testing for improved debugging of faulty boards
• Card Edge Testing with a powerful IDDE software
• Powerful QSM techniuqe for improved coverage when the function of
  the device is not known
• DEF 0053/1 compliance for the safe operating limits on backdriving

Analog

• 3 Analog channels can be connected to any channels
• 12 bit resolution in 2.5V, 5V, 8V and 13V ranges
• 8192 deep by 12 bits RAM behind each channel
• Selectable drive source impedance of 50 Ohm, 200 Ohm, 1K Ohm,
  10K Ohm and 100K Ohm
• ±250 milli amps per channel
• Choose the drive pattern from sine, cos, tan, square, triangular and
  ramp with programable amplitude, phase and frequency

QSM
QSM is a propritary test technique developed by Qmax to effectively debug boards
with no information about the devices being used, but with a known good board.

• User selectable voltage from 2.5V / 8V / 13V
• User selectable frequency 40Hz / 312Hz / 2500Hz
• User selectable current limit

Repair Trouble-shooting Applications :
