In-circuit
Functional Tester with TTL and CMOS Logic
for PCB Repair and Troubleshooting Applications
Qmax
QT100X 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 seek 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 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 unknown
- DEF 0053/1 compliance for the safe operating limits on backdriving

QSM
QSM is a propritary test technique developed
by Qmax, to effectively debug boards
with no information about the devices being used
- User selectable voltages: 2.5V / 8V /
19V / 32V
- User selectable frequencies: 40 Hz / 312 Hz /
2500 Hz
- User selectable current limit
