*Modules not included
The BK Precision DAS1800 is able to measure and record at the same time up to 40 channels at 1 MSa/s/ch and stream the data directly to the solid-state drive. For the slow changing parameters, the D18-MUX8 multiplexed module provides 8 inputs per module (up to 80 channels per system).
Base Unit
Note: All specifications apply to the unit after a temperature stabilization time of 60 minutes over an ambient temperature range of 23 °C ± 5 °C.
