3152A Specifications A-5
For trigger operation when synchronized, the trigger circuit in
the master module has control of the sample clock for all
modules. Therefore, the master module must be triggered
before any slave can output it's waveform.
Backplane Multi-
Module
Synchronization
Multiple Model 3152A modules may be synchronized. A master
Model 3152A module provides the necessary signals to slave
Model 3152A modules to achieve synchronization. The signals
required are sample clock (distributed on ECLTRG0) and
another signal (distributed on TTLTRG1). Phase offset is
settable (in degrees) for each slave module with respect to the
master module output.
