EMC Warnings
EN 55011 Class A Warning
This is a Class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
The XGS-600 was tested with Agilent Technologies manufactured gauge cables whose
pigtails are connected to the XGS-600 ground stud, and with I/O cables (for remote control,
serial communications and set points) employing combined foil-braid shields and metal
shell connectors with the shields connected to the XGS-600 chassis. Compliance with FCC
Part 15 rules and the European Union's EMI requirements cannot be assured unless Agilent
Technologies supplied gauge cables, foil-braid shielded I/O cables with metal shell
connectors are used and the included clamp-on ferrite bead is installed onto the AC power
(mains) cord. Failure to install the unit in this way may result in the failure to meet the
requirements for radiated emissions and susceptibility.
When using glass BA type gauges, it is possible that the limits for radiated emissions may be
exceeded under certain operating conditions due to the lack of shielding of these devices.
Add supplemental shielding for the glass BA gauge by installing a grounded metal cage or
screen that completely surrounds the gauge, but still allows for air flow. This reduces
emissions to acceptable levels and provides additional protection against accidental
breakage of the glass BA gauge.
FCC
This device complies with Part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesirable
operation.
NOTE The equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to Part 15 of the FCC
rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is
operated in a commercial environment. This equipment
generated, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential
area is also likely to cause harmful radio communications
interference in which case the user will be required to correct
the interference at his own expense.
