More about the MeasureReady 155 precision current voltage source

For applications where noise matters

The 155 precision voltage source and current source is designed for demanding scientific and engineering applications, where a high-quality, ultra low noise current source or low noise voltage reference is required, such as:

• Precision DC I-V and C-V curve measurements of novel materials and early-stage devices
• AC impedance measurements
• Accurate resistance, magneto-resistance, and resistivity measurements
• Low-noise bias voltages/currents for characterizing new heterostructures
• High-accuracy device testing
• Very low power excitation of sensitive materials like organics
• Controlled characterization of low resistance and superconducting materials
• Low-noise excitation of sensors for improved measurement accuracy
• Hall effect measurements to determine carrier concentrations/mobilities
• Variable temperature device/material characterization using a cryogenic probe station
• Sensitive electrochemical experiments

Full connectivity

USB and LAN connectivity provide convenient integration with systems using LabVIEW™, IVI.NET, and other software. Interfacing is straightforward using IVI-class drivers and industry-standard SCPI commands.

Options

GPIB-LAN-CONVERT GPIB to LAN converter
For applications requiring IEEE-488 communications, this converter plugs into the instrument’s LAN port and creates a GPIB-compatible interface. Note that network timing may be affected when using parallel to serial converters. Delays vary with the amount of data transferred and the converter’s activity as messages are received.

Be future-ready with

With free online software updates, your instrument can always have the most current capabilities. And as Lake Shore introduces new options in the future, you can purchase and download them to your instrument. This allows the 155 to grow as your measurement needs evolve.

A perfect pair

Combined with a quality digital meter such as the Keysight 34420A, the 155 I/V source provides greater measurement flexibility and performance when compared to some traditional all-in-one source-measure units (SMUs):

• The ability to select the meter performance best suited to experiment needs
• The ability to measure at contact points independent of the source contacts
• Well-suited to cryogenic probing, using standard or quasi-Kelvin probes
• Simple triggering link available between the 155 and meter
