Emc - TTI TGR1040 Manual Del Usuario

This instrument has been designed to meet the requirements of the EMC Directive 2004/108/EC.
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:
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 : 4kV air, 4kV contact, Performance A.
b) EN61000-4-3 (1997) Electromagnetic Field, 3V/m, 80% AM at 1kHz, Performance A.
c) EN61000-4-11 (1994) Voltage Interrupt, 1 cycle, 100%, Performance A.
d) EN61000-4-4 (1995) Fast Transient, 1kV peak (AC line), 0.5kV peak (signal lines and
RS232/GPIB ports), Performance A.
e) EN61000-4-5 (1995) Surge, 0.5kV (line to line), 1kV (line to ground), Performance A.
f) EN61000-4-6 (1996) Conducted RF, 3V, 80% AM at 1kHz (AC line only; signal
connections <3m 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.
b) after opening the case for any reason ensure that all signal and ground connections are
remade correctly before replacing the cover. Always ensure all case screws are correctly
refitted and tightened.
c) In the event of part replacement becoming necessary, only use components of an identical
type, see the Service Manual.
