J. Kissel WP 7847 ECR E1500386 IIET Ticket 11551 I've installed a copy-and-paste of the X end's hardware injection library part and its associated connection the DAC. This is in the event that we control the O3 interferometer with ETMX instead of ETMY. In that event, we'll need to switch to using PCALX as our calibration line producer, which means that we'll have to switch to using PCALY as our hardware injection producer. This comes with the following new channels stored in the frames at 16 kHz: H1:CAL-PINJY_HARDWARE_OUT_DQ H1:CAL-PINJY_CW_OUT_DQ H1:CAL-PINJY_TRANSIENT_OUT_DQ and an upgraded, uint32 ODC channel sampled at 256, H1:CAL-PINJY_ODC_CHANNEL_OUT_DQ I'll call the corresponding MEDM screen from the site map once these changes are installed tomorrow. Attached are screenshots of the Simulink model, - [...]_Before.png shows the top level h1caley.mdl before the change, having only the ODC channel below the main PCAL system block, - [...]_After.png shows the top level after the change - [...]_LibraryPart.png reminds us what's in the innards of the library part
