keith3390-ioc 0.5.1

Description:

keith3390ioc 0.5.1

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.
