Hardware Support

Support for heterogeneous sensor hardware is a central design component of SCOS Sensor. Different signal analyzers and networked sensor components interface with SCOS Sensor through SCOS plugins. This page catalogs the current stock of plugins and the hardware for which they provide SCOS compatibility.

Instructions for getting started using either Tektronix® or Ettus signal analyzers are provided in Tutorial 2.

Signal Analyzers

These plugins implement signal analyzer interfaces which expose the functionality of a given signal analyzer to SCOS Sensor. The repositories containing these plugins may also provide other files, such as Docker base images, which are required to use the supported hardware. Additional drivers may be required which are not contained within these repositories for licensing reasons. To configure SCOS Sensor a given signal analyzer, review the instructions in the plugin repository. The following plugins exist to provide support for signal analyzers:

SCOS Plugin	Supports Devices	Notes
scos-keysight	Keysight N6841A	Outdated, not currently maintained
scos-tekrsa	Tektronix RSA3xx, RSA5xx, and RSA6xx	Requires additional drivers from Tektronix
scos-usrp	Ettus Research USRP Bus Series (B2xx)

For more information on writing plugins to support new new hardware, see the SCOS Actions documentation.

Preselectors

NTIA/ITS has created a general software API to control RF preselectors, regardless of their components and control mechanisms. Read more about the preselector API and the supported components in the NTIA/Preselector repository. Additionally, read about setup of preselectors in SCOS Sensor at the Preselector Support page.

Relays

SCOS Sensor can be configured with zero or more network controlled relays. Relay support is provided by the NTIA/ITS Preselector API package. Each relay is configured by its own JSON file in the relay configuration directory, which is configs/switches by default. An instance of ControlByWebWebRelay will be created for each relay configuration file placed in this directory, and all instances will be added to a switches dictionary in scos-actions.hardware. In addition, each relay is registered to provide status through the SCOS Sensor status endpoint as specified in the relay configuration file (see the Preselector API documentation for additional details).
