Managing Multiple-mainframe Measurements
In a single-mainframe measurement, the Agilent E1432A communicates with
other Agilent E1432As 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 Agilent E1432A modules
