5 electronic measurement pitfalls you’ve probably forgotten about…

Kevin Carmichael, of Lake Shore Cryotronics, has authored a paper outlining common errors that can be made during precision electronic measurements. Whether you are new to electronic device measurements or a pro, you’ll want to avoid these pitfalls to prevent:

  • Voltage errors
  • Current leakage
  • Ground loops
  • Field-induced interference
  • Source-related noise

About the Author

Kevin Carmichael is Senior Marketing Product Manager for Lake Shore Cryotronics responsible for material characterisation systems and instrumentation. This includes the company’s new line of high-performance, simple-to-use MeasureReady™ I/V sources for engineers and scientists requiring a very precise, low-noise source of current or voltage in the lab.


Lake Shore’s 7400 Vibrating Sample Magnetometer is the most sensitive available today

VSM_SQLake Shore’s Vibrating Sample Magnetometer systems (VSM) can measure all types of magnetic materials in bulk, powder, thin film, single crystal, and liquid form, and the latest 7400 series Vibrating Sample Magnetometer is the most sensitive VSM available today.

This VSM features a noise floor of 1 x 10-7 emu at 10 seconds/point sampling, 4 x 10-7 emu at 1 second per point and 7.5 x 10-7 emu at 0.1 seconds per point. In addition to providing the lowest noise floor, the 7400’s patented technology leads to a stability of 0.05% per day which surpasses the stability of any other commercial VSM.

Under full software automation it can measure and record hysteresis M(H) loops, torque curves, isothermal and DC demagnetisation remanence curves, and temperature dependent magnetic properties.

Models based on variable gap 4″, 7″ and 10″ electromagnets are available, providing field strengths to above 3 T. While variable gap magnets allow for easy reconfiguration of the magnet gap to accommodate large samples of up to 1″.

Materials science: New MicroMag™ catalogue from Lake Shore

PMC_Catalogue_CoverLake Shore’s range of materials characterisation systems were complemented earlier this year by the company’s acquisition of Princeton Measurements Corporation and its range of MicroMag™ magnetometers.

Consequently, a new Lake Shore MicroMag™  catalogue has just been released to add to the two existing publications covering products for advanced materials research. The three downloadable catalogues now encompass:

NewCataloguesLake Shore has grown to become a leading provider of the sensors, instruments, and systems that materials researchers increasingly rely upon for exploring and developing new magnetic, electronic, electro-optic, and related materials.

Lake Shore launch CVT Probe Tips

CVT_tipContinuously Variable Temperature (CVT) probe tips are a new design from Lake Shore Cryotronics that enable uninterrupted or unattended variable temperature measurements without the need to raise the DC/RF probe off the sample between major temperature excursions.

Fully compatible with current and previous models of Lake Shore Cryogenic Probe Stations, the integrated flexible section compensates for the thermal expansion that occurs in the probe arm when the sample stage temperature is changed. With non-CVT tips, this can result in a probe movement of approximately 500 µm between room temperature and 4 K; with CVT probe tips, this movement is eliminated.

The CVT probe tips are currently available in tungsten – with tip radius options of 10 µm and 25 µm, and beryllium copper – with a tip radius of 25 µm.
