Thursday maintenance summary

Today turned into an impromptu maintenance day

DAQ

Maddie, Jim, Dave:

h1fw0 work, please see previous alog. DAQ broadcaster reconfigured to add  H1:SUS-ETMY_LKIN_P_LO_DQ channel to DMT for Maddie. DAQ restarted to support all of today's model changes

OMCPI Beacon Alignmnet [WP5991]

Shiela:

h1omcpi mode changed, required DAQ restart (slow chans change only).

SUS-PI DAMP quad PD data transfer to ITM-PI [WP5997]

Matt, Carl, Ross, Dave:

A new RFM channel was created on each arm to transfer the mux'ed ETM QUAD-PD I&Q phase to the corner station. The 8 channels are sent from the SUSETM-PI model via Dolphin to the PEM model. This model muxes the 8 channels to one new RFM, which is sent to the corner. The h1omc model receives the RFM channel, demuxes it to 8 channels and sends these (via Dolphin) to the h1susitmpi model. The h1susitmpi model receives 16 new channels, 8 per arm.

The following models were restarted: h1susetmxpi, h1pemex, h1susetmypi, h1pemey, h1omc, h1susitmpi. The DAQ was restarted.

h1susetm[x,y]pi has some fast channel renames:

+: fast channel H1:SUS-ETMX_PI_DOWNCONV1_DEMOD_I_OUT_DQ added to the DAQ
+: fast channel H1:SUS-ETMX_PI_DOWNCONV1_DEMOD_Q_OUT_DQ added to the DAQ
+: fast channel H1:SUS-ETMX_PI_DOWNCONV2_DEMOD_I_OUT_DQ added to the DAQ
+: fast channel H1:SUS-ETMX_PI_DOWNCONV2_DEMOD_Q_OUT_DQ added to the DAQ
+: fast channel H1:SUS-ETMX_PI_DOWNCONV3_DEMOD_I_OUT_DQ added to the DAQ
+: fast channel H1:SUS-ETMX_PI_DOWNCONV3_DEMOD_Q_OUT_DQ added to the DAQ
+: fast channel H1:SUS-ETMX_PI_DOWNCONV4_DEMOD_I_OUT_DQ added to the DAQ
+: fast channel H1:SUS-ETMX_PI_DOWNCONV4_DEMOD_Q_OUT_DQ added to the DAQ
-: fast channel H1:SUS-ETMX_PI_DOWNCONV_DOWNCONV1_DEMOD_I_OUT_DQ removed from DAQ
-: fast channel H1:SUS-ETMX_PI_DOWNCONV_DOWNCONV1_DEMOD_Q_OUT_DQ removed from DAQ
-: fast channel H1:SUS-ETMX_PI_DOWNCONV_DOWNCONV2_DEMOD_I_OUT_DQ removed from DAQ
-: fast channel H1:SUS-ETMX_PI_DOWNCONV_DOWNCONV2_DEMOD_Q_OUT_DQ removed from DAQ
-: fast channel H1:SUS-ETMX_PI_DOWNCONV_DOWNCONV3_DEMOD_I_OUT_DQ removed from DAQ
-: fast channel H1:SUS-ETMX_PI_DOWNCONV_DOWNCONV3_DEMOD_Q_OUT_DQ removed from DAQ
-: fast channel H1:SUS-ETMX_PI_DOWNCONV_DOWNCONV4_DEMOD_I_OUT_DQ removed from DAQ
-: fast channel H1:SUS-ETMX_PI_DOWNCONV_DOWNCONV4_DEMOD_Q_OUT_DQ removed from DAQ
 

which may cause some issues replaying old data.

After the addition of the RFM channel, so far we have not seen any IPC errors.

PEM changes [WP5998]

Robert, Dave:

PEMCS was changed to read three unused ADC channels into the model. Due to broken ADC channels, on the fifth ADC the last two channels (30 and 31) were upgraded to 16kHz and added to the science frame. The broken channels were removed from the frame, resulting in a nett reduction of science data.

At EX and EY additional ADC channels were ingested into pem (was ADC0 chans 8-13, now chans 8-23). At EY, four of these new channels were added to the DAQ science frame at 2kHz.
