We are pleased to announce that BB3 firmware version 1.7 has been released. As before, you can find instructions for the firmware upgrade in Chapter 13.
In this version, 42 published issues (fixes and improvements) have been resolved thanks in large part to your feedback and suggestions. We would highlight the following features:
- Support for three new modules: PREL6, MUX14D and MIO168 in combination with AFE3 expansion board.
- Simple function generator that can be activated on power modules (DCP and DCM) as well as on SMX and MIO. One of the interesting options is the ability to generate half- and full-rectified waveform on a DCP module which can be used to simulate rectified AC mains for testing the final stage of power supply, battery charger, etc. Set voltage go up to 80 V and current up to 10 A if two coupled DCP modules are used.
- Modified Data logger (DLOG) that now accepts more than 4 signals, sampling speeds over 1 KSPS and operation with mixed signals (analog and digital). Furthermore, it is possible to insert bookmarks (via PC or UART port on the front panel) using SCPI commands during data logging.
- UART support: it is now possible to communicate with BB3 using the DIN1/DOUT1 pins on the front panel. Three modes are supported: Buffer, SCPI and Bookmark. in SCPI mode, it is possible for an external device (another BB3 or D.U.T.) to directly control the BB3 using supported SCPI commands.
- Pinout page: the module Info page now also contains a Pinout page showing the module terminals as well as all resource numbers which can simplify SCPI programming.
Updated versions of the English User Manual and SCPI reference guide are also now available and include changes introduced by firmware v1.7. Unfortunately the German version of User Manual is not synchronized with this firmware version because we no longer have a person willing to do so (If anyone is interested, feel free to contact us).
If you find this firmware version useful, feel free to donate to our Liberapay account, to allow further development of free versions. Thanks in advance for that, and you can follow our further activities here, on Twitter, GitHub and our Discord server.
