HP (Hewlett-Packard) HP E1433A Speaker System User Manual


 
Managing Multiple-mainframe Measurements
In a single-mainframe measurement, the HP E1433A communicates with
other HP E1433As 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
you can make in a multiple mainframe environment.
You cannot perform the following types of multiple mainframe measurements:
q Unequal pre-trigger delay settings between mainframes
q Channel triggering by channels in Mainframe B
q Lower spans or longer blocksizes in Mainframe B
q Different digital filter settling times between HP E1433A modules
