Ttre 3575A
Option 002
is a
lully
progammable
instrument
with dual
BCD
oulputs and a coinplete
remote
control capabi.lity.
Like
the Option 001,
the
3575A
Option
001 is
equipped with dual
panel meters for sinlultaneous
amplitude
and
phase
presentations.
Dral arBlog
oulputs are
provided
along with the
BCD outputs
to make
the
instrument cunpatible
with
various types of
control sys-
tems
and
recording devices.
