Important Timing Settings
Recommended values from LAT integration in system clock ticks
- Delay from CAL trigger discriminator to TEM trigger primitive formation (GTEM/GCCC/trg_alignment:0-7) : 0
- Delay from TKR trigger discriminator to TEM trigger primitive formation (GTEM/GTCC/trg_alignment:0-7) : 5
- Stretch width of CAL trigger primitive (GTEM/GCCC/trg_alignment:8-15) : 15
- Hold trigger primitive for TEM diagnostic latching of CAL trigger primitive (GTEM/GCCC/trg_alignment:16-23) : 8
- Hold trigger primitive for TEM diagnostic latching of TKR trigger primitive (GTEM/GTCC/trg_alignment:16-23) : 9
The values shown below are based on the LAT Alignment and we will use these as default for CU tests. Note that this is for the flight configuration B2 that became LAT701 config. TEM diagnostics are not enabled and they will change these values.
