7.4.3 DAC interface configuration
Figure 7.15: Configuration Menu of the DAC Interface.
The
PICO
SCALE
offers five DAC outputs that can be configured in the
DAC Interface
panel. DAC
1 is a fast 10 MHz output channel with 12 bit r
esolution, DAC 2
–
5 have 16 bit resolution but their
sample rate is limited to 200 kHz. The corresponding bit widths and sample rates are displayed in
the bottom right corner of each con
fi
guration panel.
Each DAC interface can be controlled by one of the following options, that can be selected via the
switch next to the drop-down menus:
•
DAC Value
A constant output with the speci
fi
ed value is generated. The range is [-1,1]
(
fl
oat64) corresponding to a
±
10 Volt output.
•
Calc Sys Index Select
The result of the speci
fi
ed calculation system is mapped to the DAC.
•
