Support Infiniium series

[suysh]

Hello,
While searching for controlling lab equipment via Python I found your code. Looks very clean, well documented, super !
In our lab we have an Keysight MSOS404A and DSOV084A. Connected via ethernet network.
While trying your code I get the following error:

Connected to:
  KEYSIGHT TECHNOLOGIES
  MSOS404A (serial MYxxxxxxxx)

VisaError: VI_ERROR_TMO (-1073807339): Timeout expired before operation completed.
  When trying query ':ACQuire:TYPE?'  (full traceback below).
  Have you checked that the timeout (currently 30,000 ms) is sufficently long?
Latest errors from the oscilloscope (FIFO queue, upto 30 errors)
 0: -113
 1: -113
 2: -420
 3: 0
....

I saw in the documentation you added support for the Infiniium series, is this also something which needs adjustment for our series?
Kind Regards, Hans

Hi Hans,

Sorry for the long delay in my response. It's good to hear you got a good impression of the package – and I wish it had worked smoothly for you too!

There are quire a few differences between the visa commands for the Infiniivision and Infiniium series, unfortunately. When I started developing the package I was not aware of this, so I didn't make a package structure that would make it easy to expand to cover both series (a base class with subclasses for the two types would have been a reasonable way to structure the package anyway, but this was not clear to me back then).

I seem to remember I did make a couple of adjustments to make it possible to at least acquire a trace from an Infiniium series scope a while back, but it might be that these adaptations have been lost in the restructuring between v3 and v4 as I haven't had access to any Infiniium scopes since then. As you have probably figured out, the error you are getting relates to the concept of acquisition type being different for the Infiniium series scopes. A quick look in the programmer's manual should sort out what the command should be replaced by – it might be that with relatively few changes in the visa commands you might get it to work with a fairly complete set of the features this package offers also for an Infiniium scope.

Best,
Andreas
