VS-10 voltage source module

This module provides programmable voltages from ±1 nV to ±10 V with a maximum of 100 mA compliance from DC to 100 kHz sinusoidal output. The VS-10 is useful for gate biasing, voltage sweep I-V curve profiling, and applications that require highly stable voltages in combination with current, resistance/conductance, and other material or electronic device measurements.

Patent-pending circuitry enables separate ranges and amplitude settings for DC and AC signal components. This allows for simultaneous DC biasing and sweeping as well as combined AC signals to be superimposed for sample and device stimulus and selective measurement by corresponding and synchronized VM-10 modules. This hybrid DC+AC signal capability can reduce or eliminate the need and complexity for dedicated DC and AC sources while providing enhanced characterization capabilities and richer measurement data and sample insights.
