The CS-3000 Series Semiconductor Curve Tracers from IWATSU are designed as a direct, modern replacement for obsolete Tektronix Curve Tracers. Featuring a familiar user interface, users can migrate and operate the system confidently in as little as one hour, even the test adapters share the same pin out and therefore are interchangeable. The series supports both IV and CV characterisation with high accuracy and flexibility.
- Up to 3,000 V peak in High Voltage mode (5000V with CS-5000 Series)
- LEAKAGE mode with 1 pA resolution
- Multiple waveforms: Rectified SINE, DC ±, LEAKAGE ±, AC
- LAN for remote control and USB for data and screen capture
Ideal for testing IGBTs, MOSFETs, transistors, and diodes, the CS-3000 Series is the perfect upgrade for users of legacy Tektronix curve tracers, including the 370, 370A and 370B and the 371, 371A and 371B.

IWATSU Semiconductor Parameter Measurement Software CS-810
Automate measurement and improve efficiency. In the past, many items had to be set manually, meaning that measurements took a long time, but by adopting the , it is possible to easily automate measurements, and furthermore, the measurement details can be saved as evidence. In addition, automatic judgment is also possible by setting the threshold value in advance.
Advantages of adoption:
- Make accurate and reliable measurements according to the measurement procedure
- Measurement content is also saved as evidence
- Auto-judgment is also possible
- Control of optional products can also be automated (e.g. temperature control of hot plate)
