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.
Serial Port not Included
A python package that gives you an API for interacting with supported Tektronix oscilloscopes over a serial interace.
We don’t provide a serial port implementation. We suggest, pyserial:
$ pip install pyserial
>>> 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 -0.004496 -0.12 -0.004495 -0.08 -0.004494 -0.12 -0.004493 -0.16 -0.004492 -0.2 -0.004491 -0.08 >>> >>> tds.x_units() 's' >>> tds.y_units() 'V' >>> >>> >>> >>> # 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:
$ pip install sphinx_rtd_theme
