Oscilloscope EMC Certifications and Compliances
European
Union
Meets the intent of Directive 89/336/EEC for Electromagnetic Compatibility.
Compliance was demonstrated to the following specifications as listed in the
Official Journal of the European Communities:
EN 61326, EMC requirements for Class A electrical equipment for measure-
ment, control, and laboratory use
1,2
IEC 61000--4--2, Electrostatic discharge immunity (Performance criterion B)
IEC 61000--4--3, RF electromagnetic field immunity (Performance criterion A)
3
IEC 61000--4--4, Electrical fast transient/burst immunity (Performance criterion B)
IEC 61000--4--5, Power line surge immunity (Performance criterion B)
IEC 61000--4--6, Conducted RF immunity (Performance criterion A)
4
IEC 61000--4--11, Voltage dips and interruptions immunity (Performance
criterion B)
EN 61000--3--2, AC power line harmonic emissions
1
Emissions that exceed the levels required by this standard may occur when
this equipment is connected to a test object.
2
To ensure compliance to the standards listed above, attach only high
quality shielded cables to this instrument. High quality shielded cables
typically are braid and foil types that have low impedance connections to
shielded connectors at both ends.
3
The increase in trace noise while subjected to a test field (3 V/m over the
frequency range 80 MHz to 1 GHz, with 80% amplitude modulation at 1 kHz)
is not to exceed 2 major divisions peak--to--peak. Ambient conducted fields
may induce triggering when the trigger threshold is offset less than 1 major
division from ground reference.
4
The increase in trace noise while subjected to a test field (3 V/m over the
frequency range 150 kHz to 80 MHz, with 80% amplitude modulation at
1 kHz) is not to exceed 1 major division peak--to--peak. Ambient conducted
fields may induce triggering when the trigger threshold is offset less than
0.5 major divisions from ground reference.
