is it possible to send commands to tektronix 1012b oscilloscope in vc++ through usb rearport at the back of the oscilloscope

Hi Mirraa,

There is a LabVIEW driver for this scope for USB on our Instrument Driver Network (ni.com/idnet) at http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=9074.  However, the Measurement Studio version at that link does not currently support USB (only serial and GPIB). 

Alternatively, you can develop your own driver using VISA, and submit this to the Instrument Driver Network for the future benefit of the community.  The following links will assist you with this:

What Is the VISA Driver Development Wizard?

Another option is to use Instrument I/O Assistant.  It will allow you to interactively communicate with the scope, and will then generate C++ code that calls VISA.  You can then use the generated code as is, or modify it as a starting point to do what you want.
