Mainframe is required. The 8080A mainframe provides
housing and power supplies for the 8081 A.
by a gate pulse from an external source or a manual
pushbutton. Internal Gate mode can only be useed with
an 8084A Word Generator module. The trigger slope
polarity and threshold level of external gate/trigger in-
puts is adjustable.
The power supplies for the 8081 A are pro-
vided by the 8080A Mainframe.
The only option for the 8081 A Rate Gener-
ator is a second copy of the operating and service
manual which can be obtained by ordering option 910.
The 8081 A is one of a complete range of
rep. rate, timing and output modules that form the
high frequency pulse generator system. Repeti-
tion rates range from 0-1 GHz and the modules are
interchangeabl e to enable you to purchase a system
exactly tailored to your requirements.
