After selecting the required
function, press
or
to select one of
two modes: Continuous or Cycle. The secondary display will indicate
Cont
or
CyCLE
, respectively (
–
Continuous mode (Cont)
: In this mode, the ramp signal is repeated
continuously. The signal will be generated according to the amplitudes and
number of steps defined in the memory, with each step taking approximately
0.33 seconds. For instance, according to the default settings (
), the
step size
of the positive slope is (end amplitude – start amplitude)/number of
steps. Therefore, the step size is (1.5 V – (–1.5 V))/15 steps = 0.2 V for
±1.5000 V
. The step size of the negative slope is (start amplitude – end
amplitude)/number of steps. Therefore, the step size is
(–1.5 V – 1.5 V)/15 steps = –0.2 V for
±1.5000 V
.
–
Cycle mode (CyCLE)
: In this mode, only one cycle of the ramp signal is
generated. The signal will be generated according to the amplitudes and
number of steps defined in the memory, with each step taking
approximately 0.33 seconds, and then the output amplitude will be
maintained at the final value of the ramp signal.
