The frequency range of 18 GHz. This section also sets forth requirements for specialized equipment for intermittent disturbance measurements.

Note. According to the IEC 107 guidelines, CISPR16-1-1 is the basic EMC standard used by the IEC product committee. As stated in the IEC 107 guidelines, products

The committee is responsible for determining the applicability of the EMC standard. CISPR and its subcommittees (corresponding to the domestic SAC/TC79 technical committee and

Its subcommittees work with these product committees to evaluate the value of specific trials for their specific products. The above product committee corresponds to the country

Internal related product technical committee.

The requirements in this section apply to electromagnetic interference (EMI) receivers and spectrum analyzers. "Measurement receiver" in this section refers to EMI

Receiver and spectrum analyzer are two types of receivers.

3 Terms and definitions

The following terms and definitions as defined in GB/T 4365-2003 apply to this document.

3.1

Bandwidth bandwidth

Bn

The width of the receiver's total selectivity curve is measured at a specified level below the midpoint of the response curve.

Note. n indicates the number of decibels (dB) of the specified level.

3.2

CISPR indication range CISPRindicatingrange

The range of indications between the maximum and minimum indications of the measurement receiver specified by the manufacturer and meeting the requirements of this section.

3.3

Charging time constant electricalchargetimeconstant

Tc

From the moment when the constant sine wave voltage is applied to the input terminal of the detection stage, until the output voltage of the detector reaches 63% of its final value,

The time used between them is the charging time constant.

Note. The charging time constant is determined as follows. a sine wave signal with a constant amplitude and a frequency equal to the intermediate frequency is applied to the input of the detector.

The level should work in the linear region of the amplifier circuit of the relevant stages. Connect an inertia-free indicator (such as a cathode ray oscilloscope) to a DC amplifier

At the measurement point in the circuit that does not affect the performance of the detector, note the instrument indication D, and then apply the same level of sine wave letter only for a limited time.

The number (envelope is a rectangular waveform), the deflection is raised to 0.63D, the duration of this signal is the charging time of the detector.

3.4

Discharge time constant electricaldischargetimeconstant

TD

From the moment the constant sine wave voltage applied to the input of the detector stage is removed, the output voltage to the detector drops to 37% of its initial value.

Up to now, the time used between them is the discharge time constant.

Note. The measurement method of the discharge time constant is similar to the measurement method of the charging time constant, but instead of applying the signal for a limited time, the applied signal is applied.

The time required to interrupt the deflection for a certain period of time to reduce the deflection indication to 0.37D is the discharge time of the detector.

3.5

Impulse pulse area impulsearea

Aimp

The area of a pulse voltage integrated over time.

V(t)dt (1)

Note 1.The impulse pulse area is sometimes referred to as the impulse pulse intensity, and the unit is usually. µVs or dB (µVs).

Note 2.The pulse spectral density D (unit. µV/MHz or dB (µV/MHz)) is directly related to the impulse pulse area. For moments with a pulse duration of T

D (µV/MHz) = 2 × 106 Aimp (µVs)

3.6

Impulse pulse bandwidth impulsebandwidth

Bimp

Bimp=

A (t)max

2G0×Aim()p

(2)

In the formula.

A(t)max---measure the receiver IF when applying an impulse pulse with an impulse pulse area of Aimp at the input of the measurement receiver

(IF) the peak of the output envelope;

G0 --- The gain of the center frequency of the circuit.

For dual critical coupled tuning transformers.

Bimp=1.05B6=1.31B3 (3)

In the formula.

Bandwidth at B3---3dB.

Note. See A.2 for details.

3.7

Note. See Appendix I for more detailed information.

3.8

The mechanical time constant of the critical damping indicator mechanicaltimeconstantofacriticalydampedindicatingin-

Strument

TM

TM=TL/2pi (4)

In the formula.

TL---Remove the free oscillation period after all damping.

Note 1.For critical damping indicators, the equation of motion of the system can be written as.

TM2(d2alpha/dt2) 2TM(dalpha/dt) alpha=ki (5)

In the formula.

----deflection indication;

i---the current flowing through the indicator;

k---The time constant of the indicator.

It can be inferred from the above equation that the time constant can also be specified as the duration of a rectangular pulse (constant amplitude), and the deflection indication produced by this rectangular pulse is equal to the amplitude.

The same continuous current as the rectangular pulse produces 35% of the steady deflection indication.

Note 2.The measurement method and adjustment method of the critical damping mechanical time constant can be obtained from one of the following methods.

a) Adjust the free oscillation period to 2piTM, then add damping so that alphaT is equal to 0.35alphamax.

b) If the oscillation period cannot be measured, adjust the damping to just below the critical value, so that the overshoot of the instrument is not more than 5%, adjust the moment of inertia, so that alphaT is equal to

0.35alphamax.

3.9

Overload factor overloadfactor

The ratio of the level of the actual linear function of the circuit (or circuit group) to the level corresponding to the instrument's full scale deflection.

Note. The range of the actual linear function of the circuit (or circuit group) is the maximum value of the steady-state response of the circuit (or circuit group) that deviates from the ideal linearity by no more than 1 dB.

Level.

3.10

Symmetric voltage

In a two-wire circuit (such as a single-phase power supply), the symmetrical voltage is the RF disturbance voltage that appears between the two wires. Sometimes called differential mode voltage.

If Va is used to represent the voltage vector between one of the power terminals and ground, Vb is the voltage vector between the other power terminal and ground.

Then the symmetrical voltage, that is, the differential mode voltage, is the difference (Va-Vb) between the Va and Vb vectors.

3.11

Weighting (eg weighting of impulse nuisance) weighting(ofe.g.impulsivedisturbance)

Converting the impulse detection voltage level of the peak detection into an indication related to the pulse repetition rate (in most cases, decreasing) to correspond

The effect of interference on radio reception.

Note 1.For analog receivers, the measurement results reflect a subjective assessment of the degree of psychological aversion (discomfort) in humans (auditory or visual, usually

Does not mean a certain degree of misunderstanding of the content expressed).

Note 2.For digital receivers, the effect of the interference presented is an objective quantity, which can be specified as a critical bit error rate (BER) or ratio.

Special error probability (BEP) (even if there is perfect error correction capability, error occurs) or choose a reproducible object that reflects objective evaluation.
