M9111A -
Keysight Technologies
The M9111A is a 1-slot, 2-quadrant PXIe module that provides stable, glitch-free sourcing and sinking, and high accuracy measurements. It offers high-throughput and measurement quality for design validation and production test of RF power amplifiers. With industry-leading output stability under extreme, dynamic load conditions and unmatched transient performance to dramatically reduce voltage droop due to pulse loading, the M9111A SMU speeds test time. The high-speed M9111A can change its output voltage, stabilize that voltage, and accurately measure current from Amps down to micro-Amps all in less than 1 ms so that you can move on to the next test as quickly as possible.

QE system provides electronics and software designed for fully automated measurement of external quantum efficiency of solar cells. All systems include probes and a fixed plate sample stage for samples up to 150 mm x 150 mm. The main system components include: custom designed software, measurement electronics, and computer system (Windows 8 operating system). The measurement involves focusing monochromatic light to a spot on the device under test, then accurately measuring the photon flux and current from the test cell. The system utilizes a dual beam configuration with lock-in detection, providing an absolute accuracy of ±3%. The QE system uses a grating monochrometer with silicon/InGaAs/Ge detectors. The system includes automatic order sorting filters and two light sources for monochromatic illumination (a Xenon- arc lamp and a halogen lamp). A single lock-in amplifier is used to measure both the reference detector and test device. The main system comes with all the hardware needed to measure quantum efficiency, a fixed plate sample stage and probes.
