**PyTek** provides a python API for interacting with Tektronix oscilloscopes over a serial
interface. It currently supports some basic commands for the TDS3000
series of Digital Phosphor Oscilloscopes, especially *capturing waveforms*
and *screen shots* from the device.

.. note:: **Serial Port not Included**

PyTek relies on a thirdparty serial port for communications, specifically
one that matches the `pyserial`_ API. It is recommended that you simply use
`pyserial`_ itself.

A python package that gives you an API for interacting with supported Tektronix
oscilloscopes over a serial interace.


.. code:: bash

$ pip install pytek

Or, from source:

.. code:: bash

$ python install


We don't provide a serial port implementation. We suggest, `pyserial`_:

.. code:: bash

$ pip install pyserial


.. code:: python

>>> from serial import Serial
>>> from pytek import TDS3k
>>> port = Serial("COM1", 9600, timeout=1)
>>> tds = TDS3k(port)
>>> # Make the scope identify itself.
>>> tds.identify()
'TEKTRONIX,TDS 3034,0,CF:91.1CT FV:v2.11 TDS3GM:v1.00 TDS3FFT:v1.00 TDS3TRG:v1.00'
>>> # Capture waveform data
>>> waveform = tds.get_waveform(start=100, stop=109)
>>> waveform
<generator object <genexpr> at 0x0238B8A0>
>>> for x,y in waveform:
... print x, y
-0.0045 -0.16
-0.004499 -0.04
-0.004498 -0.04
-0.004497 -0.12

-0.004494 -0.12
-0.004493 -0.16
-0.004492 -0.2
-0.004491 -0.08
>>> tds.x_units()
>>> tds.y_units()
>>> # Grab a screen shot (this will take a few minutes).
>>> ofile = open("screenshot.tiff", "wb")
>>> tds.screenshot(ofile, "tiff")
>>> #Fin.
>>> tds.close()


You'll need a serial port interface. See the "`Serial?`_" section, above.

To build the sphinx docs from source (as is), you'll need the `sphinx_rtd_theme`_:

.. code:: bash

$ pip install sphinx_rtd_theme


PyTek package includes the following extras (optional installs):

Adds `pyserial`_ package as a requirement, the recommended serial port interface.

Adds `sphinx_rtd_theme`_ package as a requirement, needed for building sphinx docs.
