Multidevice synchronization
Lock-in amplifiers and arbitrary waveform generators can now be synchronized using the multidevice synchronization (MDS) function from Zurich Instruments. Multiple instruments can be connected and controlled from one user-friendly interface. MDS synchronizes both the 10 MHz clock and the sampling rate of each instrument and allows measurements to be taken simultaneously on multiple devices. Data points are labeled with corresponding time stamps, which allows for clear waveform digitization and analysis. The company’s LabOne software has integrated tools for signal analysis that reduce the complexity of setups involving such instruments as sweepers, oscilloscopes, and digitizers. Existing Zurich Instruments users can add MDS functionality free of charge by updating LabOne to version 17.12. Applications include quantum computing setups, quantum transport, and synchrotron beam-position monitoring. Zurich Instruments AG, Technoparkstrasse 1, 8005 Zürich, Switzerland, www.zhinst.com
Magnetic measurement instruments
Lake Shore Cryotronics offers its F41 single-axis and F71 multiaxis teslameters, compatible FP series Hall probes, and 2Dex Hall sensors for precise, convenient measurement in challenging applications. They have TruZero technology that minimizes misalignment voltages and eliminates the need to rezero a probe. The Hall sensors feature high sensitivity and linearity over a wide field range. A small, ultrathin active area on the sensors ensures accurate field readings and all but eliminates planar Hall effect errors that can cause measurement offsets in current-generation three-axis probes. The instruments work equally well on a benchtop or in a rack. Probe swapping is simplified by a compact, quick-release connector with integrated calibration data that are used for all probes.

Fast-sampling digitizer cards
Spectrum Instrumentation has extended the performance range of its general-purpose M2p.59xx series of PCIe 16-bit digitizer cards by adding five models that increase the maximum sampling rate from 80 MS/s to 125 MS/s. Because they can capture a wide range of electronic signals, they are suitable for use in applications in which signals in the DC to 50 MHz frequency range need to be acquired and analyzed fast and accurately. The series includes models that provide one, two, four, or eight input channels. Multichannel models each have their own analog-to-digital converter and signal conditioning circuitry to allow fully synchronous acquisitions on all the inputs. Applications include big physics experiments, lidar, lasers, and medical science. Spectrum Instrumentation Corp, 15 Warren St, Ste 25, Hackensack, NJ 07601, https://spectrum-instrumentation.com
Recirculating cryocooler
Janis’s model RGC4 recirculating cryocooler eliminates the need for costly liquid helium in “wet” cryogenic probe station systems and instead delivers a stream of 4 K helium to the probe station. After cooling the sample and thermal shields, helium gas exits the probe station, is recooled by the cryocooler, and reenters the probe station at 4 K in continuous closed-loop circulation. Physically decoupling the cryocooler from the probe station reduces the vibration displacement at the sample location by more than an order of magnitude. The model RGC4 can be used with other continuous-flow cryostats, such as the Janis ST-500 microscopy cryostat. The combination provides positional stability to less than 10 nm and is suitable for microphotoluminescence, micro-Raman, and other vibration-sensitive techniques.

Interferometric atomic displacement sensor
Oxford Instruments Asylum Research has developed an interferometric displacement sensor (IDS) that directly measures the displacement of atomic force microscope (AFM) cantilevers. The IDS interfaces the optical system of Asylum’s Cypher AFM with an external laser Doppler vibrometer. It provides a complementary method of detecting true tip displacement rather than replacing the standard laser and detector. The module can be used as a secondary channel of information during regular AFM measurements, or it can replace an optical-beam deflection (OBD) channel for any dynamic imaging mode. According to Asylum, its IDS option can provide more accurate electromechanical measurements than is possible with the traditional OBD or “beam bounce” technique in piezoelectric and ferroelectric materials research.
