QT4810A Transistor Curve Tracer
A bench instrument that displays the characteristic curves of transistors, FETs, and diodes on screen so you can see how a device behaves instead of relying on a single-point measurement. Step sources, a wide collector sweep, and dual-cluster display make it suitable for both detailed analysis and quick comparison.
Use it for: incoming inspection of semiconductors, device matching and selection, failure analysis, R&D labs, repair benches, and electronics teaching labs.
You can:
Display clear characteristic curves for bipolar transistors, FETs, and diodes
Compare two devices at once with the dual-cluster display
Test parallel FETs with the conjugation function
Measure collector current from 20 µA/div to 1 A/div, and collector voltage from 0.05 V/div to 500 V/div
Check diode reverse leakage with sensitive ranges from 2 µA/div
Drive the base with step current (1 µA to 0.1 A per stage) or step voltage (0.05 V to 2 V per stage)
Set 4 to 10 steps per cluster, positive or negative polarity, and continuous or single-cluster stepping
Collector sweep supply:
Range Max current
0 to 5 V 10 A
0 to 20 V 2.5 A
0 to 100 V 0.5 A
0 to 500 V 0.1 A
Other specs: dissipation (limiting) resistance selectable from 0.5 Ω up to 500 kΩ, step rate 200 steps/s (at 50 Hz), typical scale accuracy ±3%, 220 V ±10% (50 Hz), 240 × 330 × 480 mm, 13.5 kg.
The QT4810 Series Transistor Curve Tracer provides clear and precise visualization of transistor characteristics, enabling engineers to analyze current amplification, base voltage, and collector sweep behavior. With step signals adjustable up to 2V per stage and collector sweep supplies ranging from 5V to 500V, it supports comprehensive transistor and FET testing. Compact yet powerful, the QT4810A offers dual-cluster display circuits, conjugation functions, and robust measurement accuracy, making it ideal for semiconductor labs, device characterization, and advanced R&D.
