Description
Outputs pulses at a
specified frequency.
Time
Outputs pulses and
changes the fre-
quency at a fixed
rate.
Time
Description
Changes the fre-
quency (higher or
lower) of the pulse
output in one step.
Time
Changes the fre-
quency from the
present frequency
at a fixed rate. The
frequency can be
accelerated or
decelerated.
Time
Changes the accel-
eration or decelera-
tion rate during
acceleration or
deceleration.
