OBH T1038 + short cable, mass locked, measured at PDM 3.14

T1023 + short cable, mass locked, measured at PDM 3.07

T1038 + 550-m cable, mass unlocked, measured at PDM (prospect) 2.87

T1023 + 550-m cable, mass unlocked, measured at PDM (prospect) 2.56
DC/DC for OBH No supply for OBH 0.30
SAM-195 Steady-state 1.00

Disk writing 11.00
Total average:

MEG + 1 x OBH(T1023) + SAM


22-hr cycle average for a typical amount of incoming data: (100 sps + 20 sps) x 3 channels x 2 bytes 4.58
MEG + 2 x OBH + SAM


11-hr cycle average for a typical amount of incoming data: (100 sps + 20 sps) x 6 channels x 2 bytes 7.78

Notes: CRM = combiner/repeater module, OBH = ocean borehole seismometer, SAM = storage acquisition module, MEG = multiple-access expandable gateway, PDM = power distribution module. DC = direct current. Power consumption is shown for a typical supply voltage of 22.4 V.
