Compliance Information
This section lists the EMC (electromagnetic compliance), safety, and
environmental standards with which the instrument complies.
EMC compliance
EC Declaration of
Conformity – EMC
Meets intent of Directive 2004/108/EC for Electromagnetic Compatibility.
Compliance was demonstrated to the following specifications as listed in the
Official Journal of the European Communities:
EN 61326-1, EN 61326-2-1.

This product is intended for use in nonresidential areas only. Use in residential areas may cause electromagnetic
interference.
2
Emissions which exceed the levels required by this standard may occur when this equipment is connected to a test
object.
3
Equipment may not meet the immunity requirements of applicable listed standards when test leads and/or test probes
are connected due to coupling of electromagnetic interference onto those leads/probes. To minimize the influence of
electromagnetic interference, minimize the loop area between the unshielded portions of signal and associated return
leads, and keep leads as far away as possible from electromagnetic disturbance sources. Twisting unshielded test leads
together is an effective way to reduce loop area. For probes, keep the ground return lead as short as possible and close
to the probe body. Some probes have accessory probe tip adapters to accomplish this most effectively. In all cases,
observe all safety instructions for the probes or leads used.
4
For compliance with the EMC standards listed here, high quality shielded interface cables should be used.
5
≤ 4.0 division waveform displacement or ≤ 8.0 division increase in peak-to-peak noise.
Residual spurious signals in the RF section can typically increase to -65 dBm when the instrument is subjected to
electromagnetic interference per the IEC 61000-4-3 test for frequencies up to 1 GHz, and to -45 dBm for frequencies
above 1GHz.
6
≤ 4.0 division waveform displacement or ≤ 8.0 division increase in peak-to-peak noise.
Residual spurious signals in the RF section can typically increase to -80 dBm when the instrument is subjected to
electromagnetic interference per the IEC 61000-4-6 test.
