- Generally
- 30-50pF per meter (typically <2m)
- 265-Ohm, 190-Ohm, 110-Ohm (quoted from various experiments)
- SCUBA-2
- 190-Ohm, 50-pf(?) single wire
- ssa-outputs use wires with twice the diameter => 190/4=47.5 Ohm
- ACT
- ~190 ohm
- Spider
- test cryostat cryo cable: 48" + 43" long, R~90 ohms (round trip) and C~180 pF between pairs
- Flight cryostat cryo cable: 3m + 45" long, R~160 ohm (round trip) and C~350pF between pairs.
