M81-SSM synchronous source measure system
An innovative architecture for coordinating low-level measurements from DC to 100 kHz
The Lake Shore MeasureReady™ M81-SSM (Synchronous Source and Measure) system provides a confident and straightforward approach for advanced measurement applications. The M81-SSM is designed to eliminate the complexity of multiple function-specific instrumentation setups, combining the convenience of DC and AC sourcing with DC and AC measurement, including a lock‑in’s sensitivity and measurement performance.
This extremely low-noise simultaneous source and measure system ensures inherently synchronized measurements from 1 to 3 source channels and from 1 to 3 measure channels per half-rack instrument — while also being highly adaptable for a range of material and device research applications. M81-SSM product overview...
Unique real-time sampling architecture for synchronous sourcing and measuring
- MeasureSync™ technology for simultaneous source module update and measure module sampling timing across all channels
- DC/AC amplitude and phase detection is user-selectable on all measure channels
- Common DAC/ADC sampling clock ensures highly precise and consistent source/measure timing coordination between 3 sources and 3 measures
Designed for scientific-grade low-level measurement applications
- Linear module power supply architecture for lowest possible source/measure noise
- Fully analog signal paths between data converters, modules, and the device under test (DUT)
- Remote modules for the shortest possible signal path to the DUT, which separates sensitive analog circuits from digital circuits and unwanted sources of interference typical of traditional single-enclosure instrument designs
The absolute precision of DC plus the detection sensitivity performance of AC instrumentation
- All source and measure channels are capable of DC and AC to 100 kHz signals
- Optimized for fundamental, harmonic, and phase AC plus DC biased measurements
- Modularity allows for flexible, user-configured modules to suit a specific application
Unique, flexible instrument/distributed module architecture
- Remote-mountable amplifier modules are interchangeable between instruments
- Modules are dynamically recognized when the system is reconfigured
- Uses a clean, simple UI and a common programming API for fast setup and a shorter learning curve
