d) EN61000-4-4 (1995)
Fast Transient: 1 kV peak (ac line), 0.5 kV peak (signal lines
and RS232/GPIB ports)
e) EN61000-4-5 (1995)
Surge: 0.5 kV (line to line), 1 kV (line to ground)
f) EN61000-4-6 (1996)
Conducted RF: 3 V, 80 % AM at 1kHz (AC line only; signal
connections <3 m not tested)
According to EN61326 the definitions of performance criteria are:
Performance criterion A:
Performance criterion B:
Performance criterion C:
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.
Class B
Class B
The instrument is Class A by product category.
'During test, normal performance within the specification
limits.'
'During test, temporary degradation or loss of function or
performance which is self-recovering'.
