EMC Compliance
This instrument meets the requirements of the EMC Directive 89/336/EEC.
Compliance was demonstrated by meeting the test limits of the following standards:
Emissions
EN61326 (1998) EMC product standard for Electrical Equipment for Measurement,
Control and Laboratory Use. Test limits used were:
a) Radiated: Class B
b) Conducted: Class B
c) Harmonics:
EN61000-3-2 (2000) Class A
The instrument is Class A by product category.
Immunity
EN61326 (1998) EMC product standard for Electrical Equipment for Measurement,
Control and Laboratory Use. Test methods, limits and performance achieved were:
a) EN61000-4-2 (1995)
Electrostatic Discharge: 4 kV air, 4 kV contact
Performance A.
b) EN61000-4-3 (1997)
Electromagnetic Field: 3 V/m, 80 % AM at 1 kHz
Performance A.
c) EN61000-4-11 (1994)
Voltage Interrupt: 1 cycle, 100 %
Performance A.
d) EN61000-4-4 (1995)
Fast Transient: 1 kV peak (ac line), 0.5 kV peak (signal lines
and RS232/GPIB ports)
Performance A.
e) EN61000-4-5 (1995)
Surge: 0.5 kV (line to line), 1 kV (line to ground)
Performance A.
f) EN61000-4-6 (1996)
Conducted RF: 3 V, 80 % AM at 1kHz (ac line only; signal
connections <3 m not tested)
Performance A.
According to EN61326 the definitions of performance criteria are:
Performance criterion A: ‘During test normal performance within the specification
limits.’
Performance criterion B: ‘During test, temporary degradation, or loss of function or
performance which is self-recovering’.
Performance criterion C: ‘During test, temporary degradation, or loss of function or
performance which requires operator intervention or system
reset occurs.’
Cautions
To ensure continued compliance with the EMC directive the
following precautions should be observed:
a) connect the generator to other equipment using only high
quality, double-screened cables.
