Phase 12B Thermal Analyzer
The Phase 12B is a subset of the Phase 12 Thermal Analyzer family. The primary difference between the standard Phase 12 Thermal Analyzer and the Phase 12B is that the Phase 12B has an internal 100A Power Booster. The high current port on the Phase 12B exists in a single 100A range with a maximum voltage of 20V. The remainder of the Phase 12B specifications are otherwise the same as those of the Phase 12, and can be found here.
The Phase 12B is intended to be paired with the Keysight GPIB controlled power supply, which is included as part of the Phase 12B Discount Accessory Package.
