Managing Multiple-mainframe Measurements

In a single mainframe measurement, the VT1433B communicates with other VT1433Bs through the TTLTRG lines. However, when using the VXI-MXI bus extender modules, the TTLTRG lines, which carry the group synchronization pulse and sample clock, are extended only in one direction. This unidirectional signal connection restricts the types of measurements that can be made in a multiple mainframe environment.

The following types of multiple mainframe measurements cannot be performed:

￿Unequal pre-trigger delay settings between mainframes

￿Channel triggering by channels in Mainframe B

￿Lower spans or longer blocksizes in Mainframe B

￿Different digital filter settling times between VT1433B modules

Ethernet or Firewire
