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 1x XC7K160T-2FFG676Eight analog cards, one HMCAD1520 + one AFE each One digital card with 1-2 SFF-8087 connectors for LA One AWG card with a TBD JESD204 DAC using unused serdes lanes (assuming 4 for 40G, one for 10G, three available)
-
ZENNECK (Jonathan Zenneck, inventor of electrically scanned CRT oscilloscope)
500 MHz or 1 GHz / 5 Gsps, 1 AFE : 1 AD9213-6GPer channel:
- 1x XC7A200T-2FFG1156
- 1x AD9213 in 6G speed grade
- 2x DDR3 800 SODIMM
Global:
- 1x XC7K160T-2FFG160T (could do six channels with direct lane to each one)
-
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?)
