        • Emailed btroph@slac.stanford.edu to see if he can find any thing on SEDA
      • Rough drawing from Kazutaka Nakahara
        • Drawing: Possibly older, is M-to-F, same part number... error...
        • Cable: He gave me is F-to-F
      • Lupe's Shop → Uploaded drawing to ePix Cables (xtrnl)

    • DC: I_MAX = 2.8[A] for both analog and digital–more than adequate

    • Transient response???
      • Min 15[ft] Typical 23[ft] up to 45[ft], expected 16[AWG] from meeting... drawing has 22[AWG]...
      • Replicate typical and worst case cables???
      • Test for breakage:
        • Need: Time-domain electrical reflectometer

Q&A

• Cabling
  • (Q) Power and pin requirements met the DC requirement?
  • (A) Yes, there x3 in parallel 22[AWG] wires for both Analog and Digital → I_MAX = 2.8[A] each
    • See CA-261-807-89 (xtrnl) for details
  • (Q) Power and pin requirements met the transient response time?
  • (A) Transient response???
