starshipraider's Introduction

Intro

TODO: talk more about the project

Project Codenames

Boards, subsystems, etc are all named after famous electrical engineers.

General

  • STARSHIPRAIDER: umbrella term for the entire project
  • CLARKE (Edith Clarke, first female EE professor in USA): the original STARSHIPRAIDER project

Oscilloscopes

Individual instrument projects are named after famous electrical engineers who made major contributions to the field of test equipment design.

All are 8 channels.

  • BLONDEL (Andre-Eugene Blondel, inventor of electromechanical oscillograph)
    8 bit: 100 MHz / 250 - 500 - 1000 Msps
    12 bit: 50 MHz / 125 - 250 - 500 Msps
    4 AFE : 1 HMCAD1520
    Two acquisition cards, 4 channels each
    One XC7A100T-2FGG676 on main board
    One DDR3 800 SODIMM on main board

  • DUDDELL (William Duddell, inventor of moving-coil mirror oscillograph)
    250 MHz / 1 Gsps, 1 AFE : 1 HMCAD1520

  • ZENNECK (Jonathan Zenneck, inventor of electrically scanned CRT oscilloscope)
    500 MHz / 4 Gsps, 1 AFE : 4 HMCAD1520

  • VOLLUM (Howard Vollum, co-inventor of triggered-sweep oscilloscope)
    1-2 GHz / 10 Gsps, 1 AFE : 1 AD9213

  • MURDOCK (Melvin Jack Murdock, co-inventor of triggered-sweep oscilloscope)
    6 GHz / 40 Gsps, 1 AFE : 4 AD9213

Probes / peripherals

  • CONWAY (VLSI pioneer, co-author of Mead & Conway)
    8-bit comparator-to-LVDS logic analyzer pod with SFF-8087 interface and high-impedance inputs

  • MEAD (other half of Mead & Conway)
    8-bit comparator-to-LVDS logic analyzer pod with SFF-8087 interface and 50 ohm inputs

  • MAXWELL (James Clerk Maxwell, discovered Maxwell's Equations)
    Kintex-7 ISERDESE2 based LA

  • TODO: Artix-7 GTP based LA??

  • DENNARD (Robert Dennard, inventor of DRAM)
    Kintex-7 GTX based LA

  • BRAUN (Karl Ferdinand Braun, inventor of optically scanned CRT oscilloscope and phased array) Low-bandwidth active probe ADA4817-1ACPZ-R7

  • HALL (discovered Hall effect) AKL-PT1 passive probe

Signal Generators

  • FLEMING (John Ambrose Fleming, inventor of vacuum tube) 4 channel 14 bit 2.5 Gsps arbitrary waveform generator, AD9739 + Kintex-7 + DDR3 SODIMM based. Need ~160 Gbps of RAM bandwidth to keep them fed

    Two channels of 14-bit LVDS per DAC = 28 LVDS pairs for data, assume clock/sync are external to FPGA Slow control: 4 wire SPI, IRQ = 5 slow lines

    4x DAC = 84 pairs (168 pins used / 4 banks / 200 allocated) + 15 slow lines

    Two xc7k160t's, two dacs + 1 sodimm of ram on each

    4GB DDR3 SODIMM, 1 GB per channel = 512 Mpoints of waveform data Probably some digital outputs (mix of LVDS and LVCMOS, and maybe some slow pin headers?)
