EPICS IOC for the Keithley 3390 Signal Generator

This is a quick'n dirty IOC based on the experimental magic-IOC application escpi, part of the EMMI ecosystem.

Essentially, here we're just bundling a Dockerfile, configuration, and some documentation for the IOC.

Versioning follows roughly the versioning of escpi.

Quick Start

The easiest way is to run the keith3390-ioc directly from its official Podman container:

$ podman run -ti --rm registry.gitlab.com/kmc3-xpp/keith3390-ioc --prefix KEITH:

Enviroment Variables and Parameters

Being essentially just a deployment of escpi, Keith-3390 responds to the same environment variables and parameters:

• --prefix the EPICS prefix to use
• --resource-manager the PyVISA resource manager to use (defaults to "@py")
• --device the PyVISA device to connect to

EPICS Process Variables

Exports the following EPICS PVs ({prefix} is as specified in the command line parameters):

• {prefix}:func the waveform to generate, must be one of "SIN", "DC", "NOISE", "SQUA", "RAMP", "USER".
• {prefix}:func_RBV the currently used wave form
• {prefix}:freq the frequency with which to generate the waveform, in Hz
• {prefix}:freq_RBV read back value of the current frequency
• {prefix}:ampl the amplitude to apply to the signal
• {prefix}:ampl_RBV read back value of the amplitude
• {prefix}:offs the signal offset (i.e. base voltage value)
• {prefix}:offs_RBV read back value of the offset
• {prefix}:onoff if a 1 is written here, the Keithley's output is turned ON (i.e. the function is being provided). If this is set to 0, the output is muted.
