7.5 Modules
The
PICO
SCALE
modules add much more versatility to your applications. These modules are the
Clock Generator
module, the
Arbitrary Signal Generator
module, the
Calculation System
module and
the
Counter
module.
7.5.1 Clock Generator
Figure 7.16: Con
fi
guration Menu of the Clock Generators.
The
PICO
SCALE
o
ff
ers two digital clock generators, which can output frequencies from 1 Hz to
10 MHz. A clock generator can be used to simply output a clock via one of the GP
I
O pins, or it
can be used inside the advanced trigger system to synchronize internal data sources with external
processes, for example.
I
n these applications, the
PICO
SCALE
generates the master clock.
All clock generators are derived from the same master clock and can thus be synchronized. As
depicted in
fi
gure 7.16, each clock generator can be con
fi
gured by a
Frequency
and a
Phase Shift
.
Enabling of each clock generator is done by the
Enable
button in the center of the each
Clock Gen-
erator
. Both generators can be synchronized to each other with a de
fi
ned phase shift by clicking
the
Synchronize
button on the left side of the window.
Continuous output of a con
fi
gured clock is realized in the
Direct
mode of the clock generator.
However, when you want to control external devices by the
PICO
SCALE
or vice versa, it is helpful
to start and/or stop the clock generators once appropriate trigger conditions are given. For this,
the
Mode
of the clock generator must be set to
Triggered
and the the corresponding start and stop
trigger indices de
fi
ned (cf.
fi
gure 7.16). The start and stop triggers are selected in the two drop-
down menus on the left side of each clock generator con
fi
guration panel. The triggers can be
con
fi
gured in the respective menu of the
Advanced Trigger
panel.
I
f the
Auto Reset Mode
is enabled,
the clock generator will listen for another start trigger after receiving a stop trigger. Otherwise the
clock generator can only be restarted by disabling and enabling it again manually. The auto reset
mode has no meaning in the direct clock generator mode.
