Ultra-Fast I-V Module
IntroductIon
Ultra-fast I-V sourcing and measurement have become increasingly important
capabilities for many technologies, including compound semiconductors,
medium power devices, non-volatile memory, MEMs (micro-electro-mechanical
devices), nanodevices, solar cells, and CMOS devices. Using pulsed I-V signals to
characterize devices rather than DC signals makes it possible to study or reduce
What Is Ultra-Fast I-V? the effects of self-heating (joule heating) or to minimize current drift or
degradation in measurements due to trapped charge. Transient I-V
measurements allow scientists and engineers to capture ultra high speed
current or voltage waveforms in the time domain or to study dynamic test Key Features and Specifications

Integrated HIgH Speed SourcIng and MeaSureMent
Each module has two independent channels. Each channel can measure
both voltage and current simultaneously with parallel 14-bit A/D converters
with deep memory allowing up to one million samples at 5ns per sample.
These high speed measurement and storage capabilities support a wide
range of high speed applications, such as characterizing isothermal pulsed
I-V and transient effects of trapped charges on a device. Each channel can
output high accuracy voltage pulses as short as 60ns with a rise time as
short as 20ns. When the instrument's Segment ARB
