Power Supply

gallia has support for controlling power supplies either directly via builtin drivers. Power supplies are mostly used for power cycling the current device under test. There is no limit in accessing power supplies, e.g. voltage or current settings can be controlled as well.

Own drivers can be included by implementing the opennetzteil.netzteil.BaseNetzteil interface[1]. On the commandline there is the --power-supply argument to specify a relevant power supply. Further, there is --power-cycle to automatically power-cycle the device under test. There is an experimental cli tool opennetzteil included in gallia. This cli tool can be used to control all supported power supplies via the cli.

The argument for --power-supply is a URI of the following form:

SCHEME://HOST:PORT/PATH?channel=CHANNEL?product_id=PRODUCT_ID

Some schemes might take additional arguments in the query string.

SCHEME

The used protocol scheme; could be tcp, http, …

HOST:PORT

For e.g. tcp or https this is the relevant host and port.

PATH

If the power supply is exposed as a local file, this might be the path.

channel

The relevant channel where the device is connected; the master channel is 0.

product_id

The product_id of the used power supply.

Supported Power Supplies

Power supplies are chosen depending on the product_id setting in the URI. The following power supplies are supported.

R&S®HMC804x

product_id

hmc804

scheme

tcp

HOST

IP address

PORT

TCP port, the device most likely uses 5025

Example:

tcp://192.0.2.5:5025?product_id=hmc804

HTTP

This is a client to the opennetzteil API which can expose power supplies over HTTP.

product_id

http

scheme

http or https

HOST

IP address

PORT

TCP port, most likely 8000 or the http defaults 80, or 443
