The
PULSE CT
variable for each channel can be set to any value between
1 and 65,535. In setting the
PULSE CT
, the x10 button will increase this
number by a factor of ten and the encoder wheel will increase/decrease
the number of pulses incrementally by one. For example, to set the count
to 1,500, first set the count to 15 using the encoder wheel, then press the
X10 button two times. The first press will increment the count to 150, and
the second to 1,500.
Pressing the OUTPUT button enables the output pulse series. The Pulse
On LED will illuminate until the pulse series is completed, at which time
the LED will extinguish. Each time the PULSE ON button is pressed, the
output pulse series will be generated.
In Internal PRF mode, the frequency (repetition rate) of the pulses are
determined by the internal frequency generator. If externally triggered, the
frequency of the pulses is determined by the frequency of the input trigger.
The delay of each of the outputs is relative to the leading edge of the T0
SYNC output.
Figure 13 Example: Pulse Count Mode
Divide By N Mode
In
Divide by N Mode
,
OUT1 and OUT3
generates continuous output
pulses (as in
Pulse Generator Mode
), and
OUT2 and OUT4
generates an
output pulse every “Nth”
Output
pulse. The divisor is set through the
Div
Out1 By
variable in the
FREQ DIV in the CHANNEL2
menu. The X10
button will multiply this number by a factor of 10.
