Product number: TH1992A
Description
The Tonghui TH1991/TH1992 series is a precise source measurement unit (SMU) with a 7″ capacitive touchscreen, Linux OS and four-quadrant voltage and current output. Single or dual-channel operation, integrated I/V curve sweep and sampling rates of up to 1,000,000 dots/s enable fast, independent tests without a PC connection.Features
- Four-quadrant source & measurement: DC and AC operation for voltage and current
- Arbitrary waveform & list scan: Generation of arbitrary waveforms with 1 µs interval
- I/V curve sweep: Automatic characteristic curve test for diodes, transistors and IGBTs
- High resolution: 6½-digit measurement with minimum 10 fA/100 nV
- Automation interfaces: RS232, USB host/device, LAN, handler I/O, SCPI
Applications
