Some updates after taking data with network analyzer.

Hervé

With the MCP testing setup (in Argonne) producing more and more data every day, and the raise of new potential devices to produce data, a data analysis framework becomes mandatory in order for everyone to be able to process and compare their results in a standard way.

The idea is to capitalize what has been already developed (Jean-François’ code) in sets of stand alone scripts, that can be applied to any data provided it is in the right imput format. The choice of Matlab for these scripts as been taken for two resons:

  • The code of Jean-François that already does the job is written in Matlab.
  • Matlab seems to be the only way to read Tektronix proprietary data format.

The idea is two reformat the code that already exist in a box-like structure simple to use for the users. From Matt’s experience testing MCP’s in Argonne two main boxes have been design with the corresponding input/outputs:

Pulse analysis framework

Does it sound reasonable: ?  Jean-François: is it possible to make your code fit is these two boxes? Are there non reasonable inputs/outputs? Are there missing inputs/outputs?

These two boxes will then be part of a grander scheme consisting of different level of data rejection/analysis:
