ARB
(cant)
Definitions
This section contains definitions, descriptions, and other pertinent information needed
to operate the ARB portion of the 3314A. Topics are listed in alphabetical order.
Amplitude sets the peak-to-peak voltage that the ARB wave must exist within
(not affected by DC Offset). The peak to peak amplitude also affects the resolution of
V HGT (see Vector Height).
Vector. The Delete Vector function deletes 1 vector from the current ARB wave.
The Return to Start Vector cannot be deleted. When a vector is deleted:
- the vector pointed to by the Vector Marker and intensified by the
Z
Axis output
is deleted
.
..
- the subsequent vectors are renumbered.
the Vector Marker
is
decremented by one and points to the vector that preceded
the deleted vector. If Vector 1 is deleted, the Vector Marker remains pointed
at
the new Vector 1.
t.
Sets the time for each unit of Vector Length.

Error 1O-vector insert not allowed-appears when you try to use more than 160
vectors. Remember that there are only 160 vectors available and are distributed among
six ARB waves. If five ARB waves contain the minimum of two vectors each, you can
have up to 150 vectors
the remaining ARB wave.
Frequency.
ARB frequency-the repetition rate of the ARB wave-is derived from
t.
When ARB frequency is changed, a new
t is computed. The limited resolution of
t may prevent you from programming an exact desired frequency.
t programs much
faster than ARB frequency.
