XIA provides PXI
and CAMAC equipment
to support instrumentation systems incorporating DXP and DGF digital
processors. Limiting system connections to a single chassis eliminates
ground loops and unwanted electronic noise pickup.
Browse PXI
support equipment necessary to operate DXP-XMAP,
Pixie-4 and Pixie-16
modules.
Browse CAMAC
support equipment necessary to operate DXP-2X
and DGF4C modules as well as the multi-element
detectors and preamplifiers from a single CAMAC crate.
XIA also sells desktop DXP
and DGF models that interface directly
to a PC, and that provide preamplifier power and bias voltage
for single-element detectors.
If possible, we strongly recommend limiting
all detector signal, communications and power connections to a
single instrumentation chassis, so as to prevent grounding and
shielding issues from arising.
Conventional detector systems typically include
a shaping amplifier, an MCA, preamplifier and detector power supplies,
and any number of gating or timing modules. When these components
are housed separately, each ground connection introduces a potential
source of noise. Unless carefully orchestrated, even a system
comprised of individually well-designed components will display
unwanted pickup due to ground loops and stray coupling.
Much of the problem is taken care of in DXP
and DGF systems inherently, as the shaping amplifier, MCA and
timing modules have already been reduced to a single printed circuit
card. Power supplies for the detector(s) and preamplifiers, as
well as ground connections at the detector must also be considered.
