• Connect low noise RF generator to inputs:
  • LCLS II
    
    • 300-30 MHz @ -20dBm
    • 300-60 MHz @ -20dBm
    • 230-60 MHz @ -23dBm
  • FACET II
    • 300 MHZ-30 @ -8dBm
  • Generate test files
    • ssh laci@cpu-b34-bp01
    • cd /afs/slac/g/lcls/users/BPM/LCLS_II/BPM/software/lcls2-py-scripts/

    • ./launch.sh striplineTakeData.py -A0 -B0 -Y stripline_yaml/*_project.yaml/000TopLevel.yaml -D stripline_yaml/*_project.yaml/config/defaults_ss.yaml -b1 -n1 -d /data/cpu-b34-bp01/bpm_data/

    Log onto a machine that you can get a Matlab license for
    • ssh <username>@rdsrv223
    • Copy test files to the proper directory
      • cd /afs/slac/g/lcls/users/BPM/LCLS_II/Data
      • scp -r laci@cpu-b34-bp01:/data/cpu-b34-bp01/bpm_data/<filename>/ <space> .
      Open data in Matlab
      • Source the following
        • bash
        • source /afs/slac/g/lcls/epics/setup/epicsenv-7.0.3.1-1.0.bash
        • export MLM_LICENSE_FILE=27010@license701,27010@license702,27010@license703 --> new
        • source /afs/slac/g/controls/development/package/matlab/setup/matlab_2017b_setup_local.bash
      • cd /afs/slac/g/lcls/users/BPM/LCLS_II/matlab
        • matlab &
        • Run SNRb84Gbe.m
          • Be sure to close Matlab when done
        • Change line 19 to have the right filename
        • Change line 28 to ADC.index=4
          • 4==chan0
          • 5==chan1
          • 6==chan2
          • 7==chan3
          Look for and record the values:
          • sig_power > 1
          • SNR > 60
    • Repeat for indices (5,6,7)
