The Keysight PD1550A is an Advanced Dynamic Power Device Analyzer and Double-Pulse Tester engineered for dynamic characterization of wide-bandgap (SiC, GaN) power semiconductor discrete devices and modules. It delivers repeatable measurement of turn-on, turn-off, switching, dynamic on-resistance, gate charge, reverse recovery, and dynamic voltage/current parameters up to 1500 V and 3000 A. The system combines isolated probe technology, solderless contact methods, and advanced measurement techniques—including probe compensation, offset adjustment, de-skewing, and common-mode noise rejection—to simplify complex power semiconductor testing. Built-in AutoCal semi-automated calibration and parasitic de-embedding address system gain, offset, and inductive errors. Safety features include an interlock-equipped enclosure and modular architecture for expandability.
