QT100X

Qmax QT100X
In-circuit Functional Tester with TTL and CMOS Logic for
PCB Repair and Trouble-shooting Applications :

Features

# Standard test library for TTL and CMOS logic families
# Power ON true digital and analog functional testing in-circuit and
out-circuit
# Automatic Pass / Fail analysis for the device under test (DUT)
# 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 in-built Short Circuit locator catering for 200 milliohms,
2 ohms and 20 ohms ranges
# Automatic BUT power control
# Powerful Waveform Display for comparision with the evaluation engine and the output
# Versatile Clipstatus 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 the Powerful IDDE Software limited to
digital devices
# 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

• 8192 deep by 8 bits behind each channel
• Selectable drive source impedance of 50 Ohm, 200 Ohm, 1K Ohm,
  10K Ohm and 100K Ohm
• ± 10 milliamps per channel maximum
• 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 / 19V / 32V
• User selectable frequency 40Hz / 312Hz / 2500Hz
• User selectable current limit

Applications

• in PCB maintenace departments & repair centres
• for board recovery personnel in loaded PCB production
• for In-coming Q/C personnel for components and loaded PCBs.
• TV / Video / Audio repair centres
• Third party repair shops
