Transport

VIs for scripting and performing transport measurments.

Installation

• Transport VIs are developed and published in LabVIEW 2019
• Please install using the VI Package Manager

Usage

Configure (Control Experiment.lvclass)

Control Experiment.vi is an entry point for the following tasks:

• record information about your sample & device
• record how the lockin is connected to your device
• configure the Krohn Hite amplifier
• sets the base path for saving data.

Control Experiment.lvclass also contains:

• Share configuration with Transport VIs or FLEX
• It also provides methods for saving ITX, TDMS, and DAT (TSV) filetypes.

Transport (Transport.lvclass)

Basic transport measurements:

• Lockin Sweep (Lockin_sweep.vi)
• Lockin vs Time (Lockin_time.vi)
• Lockin vs TimeDelay (THz_TimeDelay.vi)

(new!) Transport Server

Basics:

Start, Stop, Get Status:

Sequence Experiments (SweepControl.lvclass)

• Sweep Control.vi: Sequencer for stepping multiple parameters. Calls VIs in Transport.lvclass
• Continuous B sweep.vi: Continusouly sweep B while asynchronously calling VIs in Transport.lvclass
• note: Development on these sequencers is being phased out and will be replaced by FLEX

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
