CHAPTER 2

Contents

2.1 Microlab Instruments

Microlab Instruments is an abstraction layer for all the GPIB/Ethernet/USB/Serial instruments in the Microlab. Allyou have to do is instantiate an instrument class. With the help of each instrument’s SCPI command reference, justask(), write(), or read() commands. No need to worry about hardware and protocol settings.

• Free software: BSD license

• Documentation: http://microlab-instruments.rtfd.org.

2.1.1 Features

• TODO

2.2 Installation

To install:

$ pip install git+https://github.com/kitmonisit/microlab-instruments

To uninstall:

$ pip uninstall microlab-instruments

To upgrade, you need to uninstall then reinstall the package. No provisions have yet been made for pip install--upgrade ....

2.3 Usage and Tutorial

2.3.1 Basics

1. Start using microlab-instruments


2. Turn on the instrument nicknamed Giratina.

3

http://microlab-instruments.rtfd.org


3. Initialize Giratina in the software environment

giratina = mi.Giratina()

4. Query Giratina for its identification string.

giratina.write('*IDN?')

5. Read Giratina‘s ASCII response

print giratina.read_ascii()

6. Putting them all together, you can write a script that asks Giratina for its identification string:


giratina = mi.Giratina()giratina.write('*IDN?')print giratina.read_ascii()

2.3.2 Types of Instruments

Two types of instruments are modeled in this Python package.

1. SCPI instruments communicate via GPIB or TCP/IP. They can receive string commands and respond in eitherASCII, binary, or IEEE-754 floating point formats.

2. I2C instruments communicate via the Aardvark adapter. They are more limited in terms of commands andresponse formats.

SCPI Instruments

The most important commands for SCPI instruments are:

• write()

• read_ascii()

• read_binary()

• read_ieee754()

The read... commands return the following data types:

• read_ascii returns human-readable str.

• read_binary technically returns str but it is not guaranteed to be human-readable. Printing the output of thisfunction will only result in gibberish in your terminal.

• read_ieee754 returns a list of numbers which are the result of a measurement SCPI query.

WARNING If you consecutively send write several commands that for which you expect a response without readingtheir respective responses in turn, you may no longer be able to segregate the data in the response buffer. For example:


giratina = mi.Giratina()giratina.write('*IDN?')giratina.write(':fetch:arr:volt?')

# The following line of code reads too much. The response to '*IDN?' is

4 Chapter 2. Contents


# not necessarily 4096 bytes long. The beginning of the response to# ':fetch:arr:volt' is read prematurely and this library does not provide# functions to reconstruct the data when it is read this way.giratina.read_ascii(bufsize=4096)

Convenience functions are provided such that write and read commands are done consecutively.

• ask_ascii()

• ask_binary()

• ask_ieee754()

SCPI Instruments Example

The following code takes a screenshot of the present display on Giratina and saves it in screenshot.jpg in thecurrent directory.

giratina.write(':DISP:ENAB ON')giratina.write(':DISP:VIEW GRAPH')giratina.write(':HCOP:SDUM:FORM JPG')giratina.write('*OPC')giratina.write(':HCOP:SDUM:DATA?')d = giratina.read_binary()

fd = open('screenshot.jpg', 'wb')fd.write(d)fd.close()

For the following code, connect a 1kΩ resistor between the positive and negative probes. We will sweep the voltagefrom 0 to 5 and measure the current. Voltage sweep values and the corresponding current values are retrieved.

import microlab_instruments as miimport numpy as np

giratina = mi.Giratina()giratina.write('*IDN?')

giratina.write(':source:function:mode voltage')giratina.write(':source:sweep:direction up')giratina.write(':source:sweep:stair double')giratina.write(':source:sweep:spacing linear')giratina.write(':source:voltage:mode sweep')giratina.write(':source:voltage:start 0')giratina.write(':source:voltage:stop 5')giratina.write(':source:voltage:points 201')giratina.write(':sens:curr:prot 0.120')giratina.write(':trigger:source aint')giratina.write(':trigger:count 201')giratina.write(':format:data real,64')giratina.write(':outp on')giratina.write(':init (@1)')giratina.ask_ascii('*OPC?')giratina.write(':output off')giratina.write(':fetch:arr:volt? (@1)')volt = np.array(giratina.read_ieee754())giratina.write(':fetch:arr:curr? (@1)')curr = np.array(giratina.read_ieee754())

2.3. Usage and Tutorial 5


res = volt / currfor m, n, o in zip(volt, curr, res):

a = '0:>20.3e'.format(m)b = '0:>17.1fmA'.format(n*1e3)c = '0:>20.3e'.format(o)print ''.join([a, b, c])

I2C Instruments

The I2C instruments are more specialized and thus we will discuss them here. The four I2C instruments are listedbelow, but you will actively use only the first three.

1. Kerrigan, an FPGA

2. Traxex, a temperature sensor

3. Xin, another temperature sensor identical to Traxex

4. Chen, an I2C multiplexer used to coordinate the Traxex and Xin

These I2C instruments communicate via the Aardvark adapter, which must be initialized first.

I2C Instruments Example

Kerrigan has only two commands, write() and read()


aa = mi.Aardvark()kerrigan = mi.Kerrigan()REGISTER = 0x11PAYLOAD = 0xAAkerrigan.write(REGISTER, PAYLOAD)print kerrigan.read(REGISTER) # This should output 0xAAprint kerrigan.read(0x12) # This should output 0x00

To use Traxex and Xin, we also need to initialize Chen. The temperature sensors have only one command,read_temp(), which returns the temperature in Celsius degrees.


aa = mi.Aardvark()chen = mi.Chen(aa)traxex = mi.Traxex(aa, chen)xin = mi.Xin(aa, chen)

print traxex.read_temp()print xin.read_temp()

2.5.2 Get Started!

Ready to contribute? Here’s how to set up microlab-instruments for local development.

1. Fork the microlab-instruments repo on GitHub.

2. Clone your fork locally:

https://github.com/kitmonisit/microlab-instruments/issues

https://github.com/kitmonisit/microlab-instruments/issues


$ git clone [email protected]:your_name_here/microlab-instruments.git

3. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set upyour fork for local development:

$ mkvirtualenv microlab-instruments$ cd microlab-instruments/$ python setup.py develop

4. Create a branch for local development:

$ git checkout -b name-of-your-bugfix-or-feature

Now you can make your changes locally.

5. When you’re done making changes, check that your changes pass flake8 and the tests, including testing otherPython versions with tox:

$ flake8 microlab-instruments tests$ python setup.py test$ tox

To get flake8 and tox, just pip install them into your virtualenv.

6. Commit your changes and push your branch to GitHub:

$ git add .$ git commit -m "Your detailed description of your changes."$ git push origin name-of-your-bugfix-or-feature

7. Submit a pull request through the GitHub website.

2.5.3 Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

1. The pull request should include tests.

2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a functionwith a docstring, and add the feature to the list in README.rst.

3. The pull request should work for Python 2.6, 2.7, and 3.3, and for PyPy. Check https://travis-ci.org/kitmonisit/microlab-instruments/pull_requests and make sure that the tests pass for all supported Pythonversions.

2.5.4 Tips

To run a subset of tests:
