Overview

The ProDAQ 3451 trigger clock function card is designed to control and synchronize multiple ProDAQ 3450 transient recorder function cards. These cards can be located in the same ProDAQ VXIbus motherboard or spread across several motherboards and LXI function card carriers. The ProDAQ 3451 function card operates either through the VXI backplane or optional external cables. The ProDAQ 3451 either can generate an internal clock/trigger or receive an external clock/trigger. The ProDAQ 3451 sends the clock/trigger to all ProDAQ 3450 transient recorder function cards through either the VXI backplane or optional external cables. Using the VXI backplane reduces the cable connections.

When using an onboard sampling clock, users can set the dual timebase mode with the ProDAQ 3451 trigger clock function card. This means that the sampling clock rate can be changed during post-trigger phase. The dual timebase mode is only available when working with internal clock. The ProDAQ 3451 trigger clock function card controls multiple-segment data acquisition and measures time between segment triggers to allow reconstruction of waveforms.
