If a third party crate is being used please check that the current drawn at 3.3 V does not sag below the effective PCI
allowed tolerance at the beginning of the acquisition.
The digitizers can use the PCI Bus at 32-bit − 33 MHz, all models, or at 64-bit − 66 MHz, DC2x2 only . The latter
allows data to be transferred with DMA at average rates up to 350 MB/s with appropriate hardware under Windows
and Linux. Otherwise, the DMA transfer rates are limited to ~100 MB/s. The CompactPCI modules are compatible
for either V I/O = 3.3 V or 5V.
3.10.2. Environmental and Physical
The modules have a Declaration of Conformity according to ISO/IEC Guide 22 and EN45014 and CE Marks of
Compliance.
The American Standard MIL-PRF-28800F has been used as the source for many of the characteristics specified
below. Those indicated with a ‘*’ are compatible with Class 3 as defined in that standard.
The front panels of the CompactPCI modules are in compliance with the IEEE 1101.10 standard.
Operating Temperature
0° to 40°C
The above values are for the ambient temperature of the room (or equivalent) where the CompactPCI crate is located.
The temperature as measured on the board may well be significantly higher. On-board temperatures above 60°C
should be avoided.
Relative Humidity*
5 to 95% (non-condensing)
Dimensions
The DC122 and DC152 conform to the 3U CompactPCI standard (100 mm × 160 mm × 20 mm). All other DC
modules conform to the 6U CompactPCI standard (233 mm × 160 mm × 20 mm).
Shock*
30 G, half-sine pulse
Vibration*
5-500 Hz, random
Safety
Complies with EN61010-1
