Troubleshooting ADC Problems
Analog systems are prone to the injection of extraneous noise, which
can de-rate the specified signal to noise performance of the supplied
equipment. Noise in the frequency spectra that could be
superimposed and detected on an analog signal can be introduced by
induction through unshielded or incorrectly shielded interface cables
or via the equipment power supplies and their respective safety
grounds. When installing analog equipment, care must be taken to
ensure that correct shielding and power supply connection rules are
followed.
Induced Noise and Correctly Shielded Cables
Induced noise will tend to be stochastic in nature and high frequency.
Please ensure that the 100-way cable connecting the 64-channel ADC
card in the MX Control to the Vicon patch panel is properly connected.
A click should be sensed at both ends of each connector when contact
has been correctly made. Please ensure that the shielding braid of any
peripheral analog equipment interface cables is firmly connected to
a SGND input on the patch panel and that the connector applied to
the peripheral equipment is correctly installed.
Avoid taking multiple taps of the analog output signal from a given
piece of peripheral equipment to several patch panels and ADC
systems as increased cable lengths and differing signal to noise
specifications can de-rate MX Control performance.
