fhimcpt: For MCPT set-up at FHI

A set of custom extractors for processing files generated by the MCPT instrument at FHI, now in the Risse group at FU Berlin.

yadg.extractors.fhimcpt.csv module

This parser handles the reading and processing of the legacy log files created by the LabView interface for the MCPT instrument at FHI, now FU Berlin. These files contain information about the timestamp, temperatures, and inlet / process flows.

yadg.extractors.fhimcpt.vna module

Used to process files generated using Agilent PNA-L N5320C via its LabVIEW driver. This file format includes a header, with the values of bandwidth and averaging, and three tab-separated columns containing the frequency \(f\), and the real and imaginary parts of the complex reflection coefficient \(\Gamma(f)\).

Note that no timestamps are present in the file and have to be supplied externally, e.g. from the file name. One trace per file. As the MCPT set-up for which this extractor was designed always uses the S11 port, the node name is is hard-coded to this value.

Usage

Available since yadg-3.0.
