PCI-6024E, PCI-6025E, and PCI-6031E. It should be set
to 0.
1 ReGlitch Reglitch DAC—When set, this bit configures the selected
DAC to have a more uniform glitch when changing the
output at the expense of a higher average glitch energy.
This bit is reserved on the PCI-MIO-16E-4,
PCI-MIO-16XE-50, PCI-MIO-16XE-10, PCI-6032E, and
PCI-6031E. It should be set to 0.
0 BipDac Bipolar DAC—This bit configures the voltage range of the
selected DAC. If this bit is set, then the DAC is configured
for bipolar operation of –V
ref
to +V
ref
.
In this mode, data
written to the DAC is interpreted in two’s complement
format. If this bit is cleared, then the DAC is configured
for unipolar operation of 0 V to +V
ref
. In this mode, data
written to the DAC is interpreted in straight binary format.
This bit is reserved on the PCI-MIO-16XE-50 and should
be set to 1. The PCI-MIO-16XE-50, PCI-6024E, and
PCI-6025E DACs are always configured in bipolar mode.
