This Part replaces GB/T 6113.102-2008 "Specification for radio disturbance and

immunity measuring apparatus and methods - Part 1-2.Radio disturbance and

immunity measuring apparatus - Ancillary equipment - Conducted disturbances".

Compared with GB/T 6113.102-2008, the main technical changes are as follows.

-- Modify the standard's name;

-- Add a "Note" to the scope according to the principle of equivalence;

-- Add 7 terms and definitions (see Clause 3);

-- Add abbreviations (see 3.2);

-- Add longitudinal conversion loss requirements for AAN (or Y-network) for

common-mode voltage measurement of category 6 (or better), category 5 (or

better), and category 3 (or better) unscreened balanced pair cables (see 7.2);

-- Add CDNE for the measurement of disturbance voltage in the frequency range of

30 MHz ~ 300 MHz (see Clause 9);

-- Add Example CDNE set-up diagrams (see Annex J).

This Part uses the translation method to equivalently adopt CISPR 16-1-2.2014

"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".

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) ohm 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 ohm for the

connected cable.
