Keysight B 2902 A Precision Source Measure is a two-channel precision source measure instrument. Keysight B 2902 A Precision Source Measure belongs to the B2900A Series Precision Source/Measure Unit line. Keysight B 2902 A Precision Source Measure supports dual-channel operation.[1][2]
The Keysight B2900A Series are bench-top source/measure units with the capability to source and measure both voltage and current. The B2902A is the dual-channel member of the B2900A Series. The B2902A possesses 100 fA and 100 nV measurement resolution and 1 pA and 1 μV sourcing resolution. The B2900A Series supports 4-wire measurement capability, high capacitance measurement mode, integrated sweep capability, high speed sampling measurement, conventional and default SCPI command sets, and USB2.0, LAN, GPIB, and digital I/O interfaces. The B2901A and B2902A support a 20 μs sampling rate at 50,000 points per second.[2]
A source measure unit sits in electrical test and characterization rather than in a wafer fabrication process chamber. A source measure unit is typically used after a device, structure, or material sample is available for contact by probes or fixtures. A source measure unit commonly supports engineering evaluation, parametric checks, failure analysis work, and automated electrical test development.
Source measure units are used wherever controlled electrical stimulus and precise electrical readback are needed from the same instrument. Source measure units are common for current voltage characterization of components, materials, and small electronic structures. Source measure units are also used to study leakage, conduction, threshold behavior, contact effects, and transient response.
