Scientific measurement library for instruments, experiments, and live-plotting

Last update: Jan 04, 2023

Overview

PyMeasure scientific package

PyMeasure makes scientific measurements easy to set up and run. The package contains a repository of instrument classes and a system for running experiment procedures, which provides graphical interfaces for graphing live data and managing queues of experiments. Both parts of the package are independent, and when combined provide all the necessary requirements for advanced measurements with only limited coding.

PyMeasure is currently under active development, so please report any issues you experience to our Issues page.

PyMeasure runs on Python 3.7-3.10, and is tested with continous-integration on Linux, macOS, and Windows.

Quick start

Check out the documentation for the quick start guide, that covers the installation of Python and PyMeasure.

There are a number of examples in the examples directory that can help you get up and running.

Comments

Harmonise instrument name definition pattern, consistently name the instrument connection argument "adapter"
Fixes #658 and adjustes the documentation accordingly.

[x] Verify that the whole adding_instruments documentation is up to date.

[x] Create a follow up Issue for changing all instruments. (correct the super invocation in Keysight N7776, LakeShore421), maybe together with the change to a "SCPI" mixin.

Channel implementation added.
Fixes #616 which complains about missing Channel implementation.

I'm done with the basic implementation:

Creation of some Base class (name is open for suggestions), which contains properties and methods which work inside the class itself (values, ask...).

Instrument is based on this Base and calls the adapter.

The Channel (maybe a different name, I made it similar to Instrument) calls the instrument's methods (instead of adapter) and write uses str.format to replace '{ch}' in a command with the channel name. I figured, this is the most common use case for a channel. If the command does not contain that variable, it is used 'as is'.

Documentation (docstring, and documentation proper, including example) and tests are not yet done.

ToDos after the implementation itself is done:

[x] Write proper documentation (including protected "channels"). Example how to add "special" channels, how to always prepend Channel name... You can use Channel.control etc.

[x] You should use the default prefix and "collection" name, unless you have several different ones. Always use asd_child

[x] Add a remark in changelog about protected "channels" and "ch_{ch}"

[x] Reorder the tests according to the split file.

[x] ensure everything from #364 is done

[x] add remove_child

[x] put the formatting in its own method

[x] add channel descriptors in order to define the children at class level.

[x] protect auto created children.

[x] Adjust the AWG to the code.

[x] Tests for setup methods (if they remain)

[x] create an issue to change instruments to this new implementation.

Closes #364

[discussion] InstrumentKit

Hello pymeasure devs,

I just wanted to take the time to bring a similar project to your attention, InstrumentKit, which I started several years ago with similar goals. Our code architecture actually looks surprisingly similar, so IK shouldn't be too foreign.

A few things that you will notice that IK has are handling of unitful quantities, extensive test coverage, and additional connection interfaces one can use.

I hope that we can learn from each other so that we can continue to help the instrumentation community.

Adapter rework
Reworking the instrument/adapter. This pull request just focuses on the official adapters, Instrument class and keeping the code base in a working condition.

Fixes #567, fixes #512, fixes #409, fixes #219.

Roadmap of different parts (PRs)

Preliminary tests of instruments/adapters in the current state #665

This pull request with changes to the official adapters and minimum changes to the instruments to use these

A test code generator.

Pull requests for changes in individual instruments (removing custom adapters, where applicable)

Open questions

[x] move read/write binary_values to adapter or instrument?

[x] query_delay in instrument.ask or should the instrument replace ask adding its own delay method if necessary?

[x] remove FakeAdapter or is there any use for it, having implemented the Protocol adapter?

[x] Deprecate the vxi11 adapter in favour of pyvisa?

[x] make SerialAdapter similar to pyvisa: timeout in ms? Or both in s?

Adapter rework

General

[x] Write tests for instruments to be changed. (tests using devices are called test_instrument_with_device.py : add appropriate comment into documentation)

[x] Harmonise ask being write+read (i.e., remove from VISAAdapter), use protocol tests to confirm it works correctly

[x] Implement waiting in Instrument.ask. time.sleep(0) takes 0.5 µs.

[x] Remove all now-unnecessary ask() implementations, read and write implementations should have all (test this)

[x] Implement over-the-wire message-traffic logging here (protocol.py), first

[x] Check timing impact of non-firing logging messages: less then 0.5 µs

[x] Roll out message-traffic logging to all Adapters, try to DRY

[x] adjust tests if instruments got changed (especially those with their own adapter.

[x] check newly added instruments

[x] Include a test generator which generates tests out of device communication

[x] Adjust the documentation: All protocol quirks are in read/write. Timing issues in ask (defaults to write + wait + read). Remove the "custom adapters in init" examples from the "connecting.rst". It's better to adjust read than to write your own adapter. If you need a special adapter, check, whether an adapter had been handed over first (for example for protocol_tests).

[x] Document how Adapters work and why only the the private methods should be overridden.

[x] Add a remark in changes.rst

Official adapters

[x] prologix adapter: remove rw_delay

[x] Adapter: Add adapter.close

[x] Can pyvisa replace telnet or change to another option (telnetlib3...) as telnetlib is deprecated PEP 594

[x] Can Prologix be based on pyvisa?

[x] deprecate vxi11 in favour of pyvisa?

Instruments and special adapters

Special Adapters ensure, that they work with the modified adapters

[x] attocube and anc300

[x] danfysik and danfysik8500: should be removable, verify, that it works as expected.

[x] lakeshore: could be moved to pyvisa, I guess

Adapter and Instrument methods

As highlighted in https://github.com/pymeasure/pymeasure/pull/559#discussion_r780658782 by @CodingMarco, there could be some design issue in the way Instrument and Adapter class implement some methods. In particular, values and ask methods implemented in Adapter class are simply calling other methods or making text processing which has nothing to do with low level instrument access. This requires, in certain circumstances, to reimplement them at Instrument class level even though no changes are needed. A possible solution is to move the default implementation of these methods from Adapter to Instrument

Allow passing serial parameters to PyVISA through PyVisaAdapter?

I'm trying to control an instrument through PyMeasure which uses a rather unorthodox serial setup: 57600 baud, 7 data bits, 1 stop bit, odd parity. All these settings are kwargs for PyVisa's get_instrument / open_resource but are not permitted by safeKeywords in visa.py. I ended up hacking my local copy of the library to validate that adding them to safeKeywords works.

Is there any compelling reason not to allow these keyword args, since they make it possible to configure more instruments?

Forking/Pickling issue when worker.start() is called?!

Using the ManagedWindow class, I can add experiments to the queue. However, once they should "start" (i.e. the next() method is used) the whole .py file gets interpreted again instead.

In the debugger I traced it down to a new thread being started when the worker is started. When Manager.next._worker.start() is called). Due to the error message below my best guess is, that it has something to do with the forking/pickling issue(s). Since I have no clue about multi-threading, I hope someone can help me fix this.

Channel of Instrument does not use overwritten Instrument methods
I am implementing another device driver based on pymeasure's Instrument and run into an issue. The device uses messages based on binary code for communication. I have overwritten Instrument.read/write/values to work with binary messages. This all works great. For a set of properties, it seemed useful to use the Channel framework.

Using Channels, however, seems to not use all the overwritten methods. In particular my custom values method is not used. I have prepared a minimal working example where the test framework nicely illustrates the problem.

The Instrument code and test file can be found at https://gist.github.com/dkriegner/7af08dc78fdd1461125e079670675bcf

The test_prop succeeds as expected, while testing the same property via a channel fails because CommonBase.values seems to be used (the string conversion causes the problem).

def test_prop_channel(): """Verify the processing the load capacity property via Channel""" with expected_protocol( DKTest, [(b'A', b'\x01'), ], ) as inst: > assert inst.ch_1.prop == 1 E assert "b'\\x01'" == 1

Is it wrong to expect that with Channels I can still overwrite the values method?

My WIP code for the real device can be found in my fork, but its not ready and lots of other things issue the problem there.

LeCroy T3DSO1204 Oscilloscope

This implements a device of a new vendor: LeCroy/Teledyne T3DSO1204 Oscilloscope.

Connection to the device is made through an TCP or USB connection.

I based the pymeasure.instruments.lecroy.LeCroyT3DSO1204 on the pymeasure.instruments.keysight.KeysightDSOX1102G but I added many functions, in particular related to the trigger.

I strived for 100% test coverage. However, to run the tests you need the hardware.

Move coordinates label to the pyqtgraph PlotItem

In order to save room in the plotwidget (especially relevant for widgets such as the DockWidget that houses multiple PlotWidgets) I here propose to make the coordinates label (now positioned just below the PlotItem in a separate, otherwise empty, VBoxLayout) a part of the PlotItem.

Critical Bug: Use of %f instead of %e for values truncates values

Hey, I've been working with this library for a while using the DSOX1102G I noticed that once I use a value smaller than 1e-6, the scope does not receive it correctly and uses the smallest value possible.

This issue occurs as the python default %f max decimal points is 6:

The more concise solution would be to use %e which is always supported by SCPI devices:

Looking at the repo there are about 19 devices use %f and not %e

This is uncaught by testing as it was never tested for.

Remove Toptica adapter

Remove the Toptica Adapter and make the ibeamSmart depending on the VISAAdapter alone. Takes hints from original PR #352 and the new issue #816.

While some basic functionality is implemented, there is an issue with writing. The laser sends a prompt, to indicate that it is ready for writing as a handshake:

Currently, read is implemented to wait for just [OK].

I would be happy to make a PR, but first need to better understand the pymeasure philosophy. I see a few options where to put this:

in a State (e.g., ready for write) +

in read

in write

Does anybody have some guidance?

Discourage the use of direct setting of interface specific properties in Instruments
Directly setting interface specific communication parameters as suggested in the documentation in the Single Interface section:

e.g.:

def __init__(self, adapter, name="Extreme 5000", baud_rate=2400, **kwargs): super().__init__( adapter, name, baud_rate=baud_rate, **kwargs )

leads to the disadvantage that this device can only be used with this particular connection. Even if a device might offer only a specific hardware interface many transparent converters exist (e.g. RS232 to Ethernet) which can make the device visible at the control computer under a different interface.

With the VisaAdapter one would only need to change the resource name and a connection would be possible if the syntax proposed in the multiple interfaces section of the documentation is used.

For the example above, this would mean:

def __init__(self, adapter, name="Extreme 5000", baud_rate=2400, **kwargs): super().__init__( adapter, name, asrl={'baud_rate': baud_rate}, **kwargs )

I therefore would propose to discourage using the "single interface" way and thereby allow the user to use hardware adapters more easily.

In particular for serial device communication I could anyhow only find the LakeShore421 device which uses the "single interface"-way

Other solutions: @bmoneke pointed out in #800 that a user can always specify an Adapter and therefore also the single interface implementation would allow to be used with communication Adapters. While this is true, it requires the user to reapply all other default parameters like read/write_termination, timeout, ... which typically are unchanged if a transparent converter is used.

Split `values` into messaging and formatting

In #784 the question arose, how to modify the message formatting (due to a binary protocol) of values while keeping the messaging (ask of the instrument or channel, respectively).

Some parts of the message formatting of values may cause problems. For example the stripping of white space chars may corrupt a binary string, as a byte might have the value of a white space char by chance.

An instrument and a channel use different ask methods (either through the adapter or the instrument), therefore, the values methods have to be different too.

Several solutions were discussed in #784. For example values could be split in a messaging part (ask) and a formatting part (the rest).

v0.11.0(Nov 19, 2022)
Version 0.11.0 (2022-11-19)

Main items of this new release:

11 new instrument drivers have been added

A method for testing instrument communication without hardware present has been added, see the documentation.

The separation between Instrument and Adapter has been improved to make future modifications easier. Adapters now focus on the hardware communication, and the communication protocol should be defined in the Instruments. Details in a section below.

The GUI is now compatible with Qt6.

We have started to clean up our API in preparation for a future version 1.0. There will be deprecations and subsequent removals, which will be prominently listed in the changelog.

Deprecated features

In preparation for a stable 1.0 release and a more consistent API, we have now started formally deprecating some features. You should get warnings if those features are used.

Adapter methods ask, values, binary_values, use Instrument methods of the same name instead.

Adapter parameter preprocess_reply, override Instrument.read instead.

Adapter.query_delay in favor of Instrument.wait_for().

Keithley 2260B: enabled property, use output_enabled instead.

New adapter and instrument mechanics

Nothing should have changed for users, this section is mainly interesting for instrument implementors.

Documentation in 'Advanced communication protocols' in 'Adding instruments'.

Adapter logs written and read messages.

Particular adapters (VISAAdapter etc.) implement the actual communication.

Instrument.control getter calls Instrument.values.

Instrument.values calls Instrument.ask, which calls Instrument.write, wait_for, and read.

All protocol quirks of an instrument should be implemented overriding Instrument.write and read.

Instrument.wait_until_read implements waiting between writing and reading.

reading/writing binary values is in the Adapter class itself.

PrologixAdapter is now based on VISAAdapter.

SerialAdapter improved to be more similar to VISAAdapter: read/write use strings, read/write_bytes bytes. - Support for termination characters added.
