We installed the amplitude stabilized RF EOM driver in the PSL. In the process the phase of the 9.1MHz modulation signal flipped by 179.3°. The measured RF power was 16.7dBm which requires H1:LSC-MOD_RF9_AM_RFSET to be set to 16.8dB.

The new controls/DAQ cables were used for both the 9.1MHz and 45.5MHz units. For the 9.1MHz unit we are using H1:ISC-430 (DB9/DAQ) and H1:ISC-432 (DB25/ctrl), whereas the 45.5MHz unit is using H1:ISC-431 (DAQ) and H1:ISC-433 (ctrl), respectively. The old cables have been pulled out of the PSL enclosure.

The RF readbacks of the 9.1MHz are currently shwoing around 18.3dBm. This is a calibration error which needs to be corrected in TwinCAT.
