The Nanometrics/Accent Optical Technologies DiVA D265EP is a Dynamic I(V) Analyzer designed for advanced semiconductor device characterization through dynamic current-voltage measurements. This instrument delivers pulsed I-V analysis with pulse widths down to 200 nanoseconds, enabling measurement from a quiescent bias point while mitigating self-heating and charge trapping effects critical to RF and high-frequency device behavior. Unlike static I-V approaches, the DiVA D265EP captures transient response and real-world operational conditions essential for accurate device modeling.
