Tektronix TDS3054C oscilloscope (oscilloscope_dimserver)

Tektronix TDS3054C oscilloscope (oscilloscope_dimserver), adapted from trash-hold/oscilloscope_dimserver. It reads horizontal_increment; sets channel, channel_enabled, vertical_scale, vertical_position and 5 more; runs single_acquisition and stop_acquisition. single_acquisition: run one single-sequence acquisition and wait for it to finish (the native sample). A hardware driver: the market serves its fake backend, so no instrument is needed.

Install

Three ways to run this device. Each one serves its fake backend: no instrument, no simulator install and no upstream checkout.

OpenAI4S (one command)

shell
openai4s lab add labs/trash-hold__oscilloscope_dimserver

Installs the device into the OpenAI4S Lab on its fake backend and starts it. First time? See setup below.

Or, in the workbench, open the Lab tab → Market → Install.

Standalone MHS endpoint

shell
git clone --depth 1 https://github.com/PKU-YuanGroup/OpenMHS.git && cd OpenMHS
PYTHONPATH=MHS/sdk/src python3 -m mhs serve labs/trash-hold__oscilloscope_dimserver --port 7400
# in a second terminal, from the same directory:
PYTHONPATH=MHS/sdk/src python3 -m mhs describe --endpoint http://127.0.0.1:7400

Serves the device as an MHS endpoint on port 7400 from an OpenMHS clone (Python 3.10 or later, standard library only); describe prints what it offers.

Any MCP host (Claude Desktop, Cursor, …)

mcp configuration
{
  "mcpServers": {
    "oscilloscope-dimserver": {
      "command": "python3",
      "args": [
        "-m",
        "mhs",
        "serve",
        "labs/trash-hold__oscilloscope_dimserver",
        "--mcp"
      ],
      "env": {
        "PYTHONPATH": "/path/to/OpenMHS/MHS/sdk/src"
      }
    }
  }
}

Add this server to the host's MCP configuration and replace /path/to/OpenMHS with the path of your OpenMHS clone. The host starts the server and talks to it on stdin and stdout.

What it does

Measures

  • horizontal_increment

Adjusts

  • channel
  • channel_enabled
  • vertical_scale
  • vertical_position
  • horizontal_scale
  • horizontal_position
  • trigger_channel
  • trigger_level
  • trigger_slope

Actions

single_acquisition
Run one single-sequence acquisition and wait for it to finish (the native sample)
stop_acquisition
Stop the acquisition (ACQ:STATE STOP); this is the safe state and takes no input

Names as the driver declares them. Units, limits and the safety declaration are in the package's REFERENCE.md.

First-time setup

The OpenAI4S workbench with the OpenMHS lab, from a source checkout:

shell
# OpenAI4S workbench with the OpenMHS lab (source checkout)
git clone --recursive https://github.com/PKU-YuanGroup/OpenAI4S.git
cd OpenAI4S && ./setup.sh && source .venv/bin/activate
openai4s lab add labs/trash-hold__oscilloscope_dimserver
openai4s serve        # open the Lab tab

The standalone endpoint and the MCP server need only an OpenMHS clone and Python 3.10 or later. More in the market's getting-started guide and on the OpenAI4S host page.

The upstream repository asserts no licence (NOASSERTION); check it before you redistribute the upstream code.

The driver package MHS/drivers/labs/trash-hold__oscilloscope_dimserver wraps the upstream code at the pinned commit. Its REFERENCE.md documents the full contract: every value, action, unit, limit and the safety declaration.
