Open source EEZ Studio for accessing your (SCPI) instruments

Sessions and history

Working with sessions is now different. The major change made is that session is not related to an instrument anymore. Session, that could represent a test case, an experiment, etc. could include work with various instruments and when new session is opened, all items exchanged with instrument will belong to that session. It you don't care about session you can simply ignore it: select and establish connection with instrument and start use it.
We are planning in future releases to add importing, exporting, printing (with some per-formatting) of sessions that could simplify reporting, exchanging results with your peers or sending it to us to simplify debugging of found issue, etc.

To open a new session use the “Start session” when you give session a name. You don't need to open any instrument to start a new session hence it is opened from the Home page.



When opened, the session name will be displayed in the top right corner and info about newly opened session will be inserted into instrument “activity log”. The session will remain opened until “Close” option is not selected and confirmed.



The list of all sessions is available from “History” tab on the Home page (second from the top). If session list is not visible select icon on the top right, or Show/hide arrow on the window splitter:



Obviously the instrument session history from now on do not necessary include what is displayed in general history, and for accessing instrument history you have to open instrument tab:



USBTMC connection

A new USBTMC type of connection is added. Unfortunately this one is not so straightforward as serial or Telnet session. For Windows you have to create USB driver for your instrument, if you don't have it already. Fortunately that is not a big task thanks to Zadig. Just install and run it, select you instrument from the list and connected USB devices and choose “Install WCID Driver”.
On the Linux it seems that due to some kernel “bug” or whatever, it is not possible to establish connection with PC that has newer USB host controller (3.0?). For older one you probably have to follow the procedure that is nicely described here under USB connection section. We didn't check what's going on on Mac so far, so if someone of you have a chance to check it please let us know.
If USB driver is properly installed and recognized, USBTMC option will appear in the instrument’s list of interfaces and to open an USBTMC connection you have to specify instrument USB VID and PID:



When connection is established you'll get info about that in the instrument activity log and you can continue to work with instrument as in case of other connections (i.e. serial or Telent/Ethernet):



PDF preview

If PDF is uploaded into activity log it’s “thumbnail” will be now displayed:



Click on it and the PDF viewer will be opened with possibility to browse thru its content, zoom in/out and rotate page orientation:

Extensions repository

So-called Instrument extensions that contains information about instrument’s SCPI command sets and parameters that EEZ Studio can use for better working with instruments are now migrated to the GitHub repository. That should simplify procedure of adding support for new instruments created by community members that has access to instruments not currently supported. We are planing to draft a first specification how to do that in M3 version.
The “View” combo-box offer various selection to the extensions:



Now, when EEZ Studio is started, it will try to make a connection to GitHub and check if new extensions or newer version of existing extensions exists. You can also initiate that procedure in any time by selecting “Update catalog” option:



… and you’ll be informed about the status of the operation:



From now on, not only instrument extensions can be added, but also extensions that accomplishes other tasks as "Advanced measurements" extensions shown above. But, since that one is still work in progress scheduled to be completed in M3 (#16) I'm not going into more details about it.

That's all about new features of the M2, I do believe that some of you will invest some time and attention to check it and come back with some feedback. Thanks!

This seems to be a great tool.  :-+
I'm already working on some macros for my HP 54516B and HP 54542A. Not precisely state of the art but yet very capable.
I will use the serial port for the communications.

Hi prasimix,

Great progress!
M3 will be  a major mailstone for me.

Keep up the good work.

Hi prasimix,

I have messed up with my EEZ Studio installation(Win7x64) when I tried to change the Rigol DS1054z interface from Ethernet to USBTMC, Studio just gone blank with an empty white window.
Uninstalled and reinstalled with Appdata folder contains only the storage.db, The scope were showing with a question mark only and when clicked again blank screen appears.

Put back the backup Appdata folder and created a new scope instrument with interface USBTMC and it gives an error - "LIBUSB_ERROR_NOT_SUPPORTED" -how to resolve this?
Is my old measurement data gone? how to recover it?

Thanks.
