Transport

VIs for scripting and performing transport measurments.

Installation

• LabVIEW 2016 32 bit is required.
• Please install using the VI Package Manager

Usage

[Control Experiment.lvclass] Control Experiment.vi provides a uniform way to:

• record information about your sample & device
• records how the lockin is connected to your device
• configures the Krohn Hite amplifier
• configures the Pickering switch if you have one
• sets the base path for saving data. It also provides methods for saving ITX, TDMS, and DAT (TSV) filetypes.

[Transport.lvclass] Basic transport measurements.

• Lockin Sweep Mode (Lockin_sweep.vi )
• Lockin vs Vsg (Lockin_Vsg.vi (Lockin_sweep.vi is preferred)
• Lockin vs Time (Lockin_time.vi)
• IV curves (Lockin_sweep.vi IV.vi)

[SweepControl.lvclass]

• Sweep Control.vi: Sequencer for stepping multiple parameters. Calls VIs in Transport.lvclass
• Continuous B sweep.vi: For sweeping B continuously while asynchronously calling VIs in Transport.lvclass

Sandbox

A test environment can be set up by configuring the following

• Multichannel Lock-in
  • Install Multichannel Lock-In. Configure simulated PXIe devices in NI MAX (Described in the Multichannel Lock-In Readme)
• PPMS Cryostat
  • Install Quantum Design's Simulate PPMS MultiVu Software
  • Install Quantum Design's QD Instrument Server
  • Install PPMS Monitor and Control. Run in Simulation mode (PPMSim)
• Check out or clone this repository and try to communicate with the virtual instruments
