The Nanometrics/Accent Optical Technologies DiVA D225 is a dual-channel synchronous pulse source measurement unit for dynamic and static characterization of semiconductor devices. It performs pulsed I(V) measurements from a quiescent bias point with pulse widths as short as 100 ns, alongside conventional DC I(V) analysis. The instrument supports Bipolar, HBT (NPN), FET, HEMT, and diode characterization in a compact single-box configuration with Windows-based control.
