* A single `SyncDDSTTL` experiment definition can be used to test DAC and TTL outputs. * For ST1/ST3, simply run this on Sayma gateware that produces hardcoded waves at SAWGs. * For ST2/ST4, either: * simply run this on Sayma gateware that produces hardcoded waves at both SAWGs and TTLs; or * set `gen_ttl_wave=true` and run this on Sayma gateware that produces hardcoded waves at SAWGs only, while both MCXs are used as TTLOuts.
