9 MHz EOM excitation cable installed
Peter installed a cable running into the PSL and into the excitation port of the 9 MHz RF driver, so we can now excite 9 MHz RFAM with the DAC.
Right now it is hooked up to LSC-EXTRA_AO_3.
To get good SNR in REFL LF and ASC NSUM I have been driving the excitation channel with 0.2 ct amplitude at 222.3 Hz. The excitation path has to be enabled on the EOM driver screen.
