Tools for UDP3305S / UDP3305S-E lab power supplies

Currently, there are the following items in this repository:

  • rec2csv is a command line tool for converting *.rec files to csv format
  • a TestController config file for these power supplies

I also have a python class for remote controlling the PSU – that one lives in a separate repostitory (UDP3305S.py).

rec2csv

Convert *.rec files created by a UNI-T UDP3305S or UPD3305S-E lab power supply to CSV format.

These lab power supplies have an undocumented RECORDER functionality that allows logging readout data to a file. Unfortunately, the file format is binary and undocumented, so a little reverse engineering was required to make use of these files.

Usage

Make the rec2csv python script executable and run it with the *.rec file as the only argument. The data is written to STDOUT.

./rec2csv foo.REC

To save the output to a file use shell redirection:

./rec2csv foo.REC > foo.csv

If you are not on LINUX, you may need to call the python interpreter explicitly:

python rec2csv foo.REC > foo.csv

TestController config file

The file under testcontroller/ is a configuration file for the popular TestController software. So far, it allows data logging for all three channels as well as in serial or parallel mode. Channel setup works but advanced functions such as recording, delayer or list mode are not implemented – I don't think they are all that usefull if you are cpntrolling the device remotely.

config output config channel1 config serial

The config file has been submitted to the Testcontroller project and is included since release V2.49. So you don't have to download it form here. Future updates will be submitted aswell.

Contributions

Thanks to Wolfram Bahmann for his input and testing the testcontroller config on a UDP3305S-E.

If you find an error, miss a feature or have figured out a piece of data that I have missed, please open an issue and let me know. Please don't submit pull-requests before discussing your issue.
