Beam Test 1999 Components
prw 2/10/99
Level 1 Trigger
• Beam Tower – Utilize ACDREQ in
L1T FPGA
– Beam pulse variable delay time w.r.t. particle arrival (includes pre-trigger)
– Input can be enabled or disabled by command
• Prototype Tower– L1T
• ACD
• CAL
• TKR
– All inputs can be enabled or disabled
prw 2/10/99
Spacecraft Simulator
• Forward commands
• Forwards telemetry data packet
• Assembles SC data packet
• Attitude simulator– Reads table position
controllers
– Transmits simulated attitude data to towers
• GPS simulator– Transmits simulated
position data to towers
– Transmits simulated GPS time data to towers
– Transmits GPS sync to towers
prw 2/10/99
Simulated Spacecraft Communications
• Cisco 2924C-XL Switch
• 10 or 100Mb/S twisted pair Ethernet between towers
• 100Base-FX fiber Ethernet uplink/downlink
• Simulated uplink for commands
• Simulated X-band downlink at 100 Mbps
prw 2/10/99
Run Control
• Enter data in web page– Boxes auto-fill
– Replaces “Run Log” pages
• Start sends the start run command – To Spacecraft Simulator
– To Beam Control
• Does NOT replace written logbook
