## Overview
|
|
|
|
Stabilizer is a flexible tool designed for quantum physics experiments. Fundamentally, Stabilizer
|
|
samples up two two analog input signals, performs digital signal processing internally, and then
|
|
generates up to two output signals.
|
|
|
|
Stabilizer firmware supports run-time configuration of the internal signal processing algorithms,
|
|
which allows for a wide variety of experimental uses, such as digital filter design or
|
|
implementation of digital lockin schemes.
|
|
|
|
This documentation is intended to bring a user up to speed on using Stabilizer and the firmware
|
|
provided by QUARTIQ and contributors.
|
|
|
|
## Hardware
|
|
|
|
The Stabilizer hardware is managed via a [separate repository](https://github.com/sinara-hw/Stabilizer).
|
|
Some information about the hardware is gathered in the [Stabilizer wiki](https://github.com/sinara-hw/Stabilizer/wiki). More detailed data, measurements, discussions, and tests have been posted in the [Stabilizer issue tracker](https://github.com/sinara-hw/Stabilizer/issues?q=is%3Aissue).

|
|
|
|
Stabilizer can be extended and coupled with a mezzanine board. One such mezzanine is the DDS upconversion/downconversion frontend Pounder. The Pounder hardware is managed via a [separate repository](https://github.com/sinara-hw/Pounder), again with [wiki](https://github.com/sinara-hw/Pounder/wiki) and [issue tracker](https://github.com/sinara-hw/Pounder/issues?q=is%3Aissue).
|
|
## Applications
|
|
|
|
This firmware offers a library of hardware and software functionality targeting the use of the Stabilizer hardware in various digital signal processing applications commonly occurring in Quantum Technology.
|
|
It provides abstractions over the fast analog inputs and outputs, time stamping, Pounder DDS interfaces and a collection of tailored and optimized digital signal processing algorithms (IIR, FIR, Lockin, PLL, reciprocal PLL, Unwrapper, Lowpass, Cosine-Sine, Atan2) in the [DSP crate]({{site.baseurl}}/firmware/dsp/index.html).
|
|
An application, which is the compiled firmware running on the device, can compose and configure these hardware and software components to implement different use cases.
|
|
Several applications are provided by default.
|
|
|
|
The following documentation links contain the application-specific settings and telemetry
|
|
information.

### Library Documentation
|
|
The Stabilizer library docs contain documentation for common components used in all Stabilizer
|
|
applications.
|
|
|
|
The Stabilizer library documentation is available [here]({{site.baseurl}}/firmware/stabilizer/index.html).
