Pulse generator instrument control using test.py

[grahamnaylorccfe]

In the provided test.py program for the pulse generator instrument, I get the following error:

---

I am running Python 3.6.0 :: Anaconda 4.3.0 (64-bit) (Ubuntu 16.04 VM).

OK, so I set up an environment to run with python 3.5 and it is good again! (Except that I don't get the graphics as it can't find pygtk and I have to set the backend for matplotlib as 'Agg' which doesn't seem to do anything).

[grahamnaylorccfe]

Using matplotlib.use('TKAgg') does allow the graphics to show though - hooray!

I was just trying to get Matplotlib running with Python3. You solved my problem ! Also there is some missing parenthesis in the print.

Anyway, I'm glad it works !

If found similar issues in the decimator test. This should be fix by #386. Thanks for pointing the problem and the solution !

Hi Thomas, Just back from Serre Chevalier. The upgrade spiral is a nightmare – more like ‘snakes and ladders’! Hope you didn’t mind me prompting Steve Leibson to mention you in his Xilinx post. Keep up the good work.
