Specification for radio disturbance and immunity measuring
apparatus and methods - Part 1-2.Radio disturbance and
immunity measuring apparatus - Coupling devices for
conducted disturbance measurements
1 Scope
This part of the GB/T 6113 series specifies the characteristics and performance of
equipment for the measurement of radio disturbance voltages and currents in the
frequency range 9 kHz ~ 1 GHz.
2 Normative references
The following referenced documents are indispensable for the application of this
document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
3 Terms, definitions and abbreviations
radio-frequency disturbance voltage appearing between the two wires in a two-wire
circuit, such as a single-phase mains supply, sometimes called the differential mode
4 Artificial mains networks
The network shall have an impedance of magnitude (150 ± 20) Ω with a phase angle
not exceeding 20°, both between the equipment terminals and between the two
equipment terminals joined together and the reference ground.
For the measurement of the symmetric voltage, a screened and balanced transformer is
5 Current and voltage probes
The current probe shall be constructed so as to enable the measurement of the current
without disconnecting the lead under measurement.
6 Coupling units for conducted current immunity measurement
The insertion loss VG/VB of two identical coupling units measured according to the
setup of Figure 9 should be within 9.6 dB and 12.6 dB in the frequency range 30 MHz
~ 150 MHz; VG is the reading of the receiver when the generator and receiver are
directly connected together; VB is the reading obtained from the measuring receiver
after inserting the coupling unit.
7 Coupling devices for measuring signal lines
AANs are used to measure (or inject) asymmetric (common mode) voltages on
unshielded symmetric signal (e.g., telecommunication) lines while rejecting the
symmetric (differential mode) signal.
8 The artificial hand and series RC element
The artificial hand consists of a (strip of) metal foil of specified dimensions, which is
placed on or wrapped around that part of the equipment normally touched by the user's
hand, in a specific configuration, described as follows.
The lead length between the RC element and the metal foil shall be 1 m. If the test set-
up requires a longer lead length, the total inductance of the lead shall be less than 1.4
μH if the frequency of measurement is near 30 MHz.
9 CDNE for measurement of disturbance voltage in frequency range 30 MHz ~ 300 MHz
The CDNE allows measurement of the asymmetric disturbance voltage Vdis generated
by the EUT on the connected cable(s).
The CDNE is contained in a metallic case. The centre of the CDNE EUT port is 30 mm
0 mm above the RGP. This height allows for a typical impedance of 150 Ω for the
connected cable.
