The new interface is mostly working:

  • The power readback is 10dB too low right now (requires software restart)
  • The modulation bias input has a gain of 1/20 rather than 1 (requires hardware swap)
  • Errors are not pushed upwards (requires software restart)

This will be fixed during next maintenance.

Here is the new medm screen for the AM-modulated AOM driver.
