NOTES:
1. Actuation time measured from system trigger. Reset/Open refers to Channel N to Reset time. Settle/Close refers to Reset to Channel N or
Channel N to Channel M time. Reset position is optically blocked.
2. At higher operating temperatures, a typical 0.1 dB and 0.3dB additive insertion loss for each channel should be expected for the strain relief
and bulkhead models respectively.
3. Measured at 23
