• continuing rigol commands and gui
  • working on pulse commands/queries

• writing module for rigol SCPI commands and pulser gui
  • done: output on/off/query, apply pulse/query pulse
  • to do: impedance, polarity, sink, all :SOURce:PULSe commands

• double PSU
  • voltage tracking finished
  • added try/except clauses s.t. psu_gui.py still runs if one or both of the PSUs are not connected
• pulser
  • began connecting/looking at SCPI commands

• starting to look at controls for rigol pulser

• finishing double PSU
  • issue w/ voltage tracking seems to be that the output must be turned off before voltage tracking is toggled, but will have to check on machine

• looking into voltage tracking options for double PSU

• finished basic controls for double PSU (output on/off, voltage, current) + added a master output option
• looked into adding controls for voltage tracking and remote lock, ran into some issues
• created github repository for GUI and for the modules we've written to control specific PSUs

• began work on GUI widget for double PSU

• finished GUI widget for single PSU, began looking into connection to double PSU
