Pulse Generator
In this section of the screen, you can configure the parameters of the Internal Pulse
Generator.
Figure 26: Internal pulse generator.
Granularity
: Indicates the number of clock cycles for each increment of the width and the
period. The main resolution is in microseconds, and four granularity steps are possible: x1,
x10, x100 and x 1000 (x1000 is equal to 1ms timing resolution).
Period
: Sets the amount of time in microseconds (determined by the granularity setting)
between consecutive pulses.
Width
: Sets the amount of time in microseconds (determined by the granularity setting)
the pulse remains at a high level before falling to a low level.
Delay
. Shows the delay calculated in microseconds as Period minus Width.
Frequency
. Shows the frequency calculated as 1/Period.
Number of Pulses
. Enables sending pulses either continuously or by a set number of
pulses. Two modes are available:
•
Continuous
–
provides a continuous operation. Click
Stop
button to end.
•
Send
–
Generates a discrete number of pulses (1 to 65535). Click
Stop
to end or
allow the process to end after sending the last pulse.
Process Start
. Allows you to manually start and stop the pulse generator. The Status LED
indicates the following:
•
Red
–
Pulse Generator is stopped
•
