Stanford Research Systems SR830 DSP Lock-In Amplifier

This repository contains the driver code and Midas frontend for Stanford Research Systems SR830 DSP Lock-In Amplifier.

Optional LAN / GPIB support can be enabled via the compilation flag GPIB_SUPPORT, more on that below.

Requirements

Requires a Midas installation with the environment variable MIDASSYS pointing to the built Midas artifacts and headers.

Build

Clone this repository, enter the cloned directory, and then build via CMake.

cmake -S "$(pwd)" -B <build-directory> -DBUILD_FRONTENDS=ON
cmake --build <build-directory> --clean-first -- -j8

Run

# Uses no flag
<build-directory>/srs_sr830_fe -e flame

# Uses flag GPIB_SUPPORT
<build-directory>/srs_sr830_gpib_fe -e flame

Including in Custom Frontend

To include this driver in a custom frontend, you should ensure the environment variable MIDASSYS points to your system install. The compilation flag GPIB_SUPPORT can be enabled by including the flag in target_compile_definitions and linking to the corresponding support target srs_sr830_gpib, as shown below. Remove these parts if LAN / GPIB support is not needed.

TODO:

# If the path to the srs_sr830 repository is outside of the frontend
# repository, you also need to provide a location for the srs_sr830
# artifacts as a second argument to `add_subdirectory`
# e.g. `./device/srs_sr830`
add_subdirectory(
    <path-to-srs_sr830-repository>
