HWP Picoscope Agent
The HWP picoscope agent interfaces with Picoscope 3403D MSO to operate the LC sensors which remotely measures the 3 dimentional position and temperature of hwp. This agent biases the LC sensors and measures the 4 channels of analog input and 8 channels of digital input.
usage: python3 agent.py [-h]
Dependencies
The Picoscope 3403 MSO requires some drivers to be compiled for your machine. To install the drivers wget the picotech library and clone the picosdk-python-wrappers repository and build the drivers:
$ wget https://labs.picotech.com/debian/pool/main/libp/libpicoipp/libpicoipp_1.3.0-4r21_amd64.deb &&\
$ wget https://labs.picotech.com/debian/pool/main/libp/libps3000a/libps3000a_2.1.0-6r570_amd64.deb &&\
$ dpkg -i *deb
$ git clone https://github.com/picotech/picosdk-python-wrappers.git
$ cd picosdk-python-wrappers
$ git switch -c 89003868b5bc52511ee57419f0afbfade25f1882
$ python3 setup.py install
Configuration File Examples
Below are useful configurations examples for the relevant OCS files and for running the agent in a docker container.
ocs-config
To configure the HWP picoscope agent we need to add a HWPPicoscopeAgent block to our ocs configuration file. Here is an example configuration block using all of the available arguments:
{'agent-class': 'HWPPicoscopeAgent',
'instance-id': 'picoscope',
'arguments': []}
Docker
Warning
This agent is only confirmed to work with the privileged flag, which disables the features that isolate a container from the host system. It is recommended that you instead run this Agent directly on the host via the Host Manager Agent.
If you want to run in a container you will need to build the image
yourself. A Dockerfile is provided in socs/docker/hwp_picoscope/
.
The HWP picoscope agent can be run via a Docker container. The following is an example of what to insert into your institution’s docker-compose file:
picoscope:
image: ocs-hwp-picoscope-agent:latest
hostname: ocs-docker
privileged: true
environment:
- INSTANCE_ID=picoscope
volumes:
- ${OCS_CONFIG_DIR}:/config:ro
- /dev:/dev
