3.6.3 Test Procedures
Test Method
Measurements may be performed at a distance other than the limit distance provided they are not
performed in the near field and the emissions to be measured can be detected by the measurement
equipment. When performing measurements at a distance other than that specified, the results shall be
extrapolated to the specified distance using an extrapolation factor of 20 dB/decade (inverse of linear
distance for field-strength measurements, inverse of linear distance-squared for power-density
measurements).
Measurements in the frequency range 10 GHz - 18GHz are typically made at a closer distance 1m,
because the instrumentation noise floor is typically close to the radiated emission limit.
Measurements in the frequency range above 18 GHz - 25GHz are typically made at a closer
distance 0.5m, because the instrumentation noise floor is typically close to the radiated emission
limit.
The average emission levels shall be measured in [duty cycle ≥ 98 or duty factor].
For the transmitter unwanted emissions shall be measured using following options below:
Refer as FCC KDB 558074, clause 11 for unwanted emissions into non-restricted bands.
Refer as FCC KDB 558074, clause 12 for unwanted emissions into restricted bands.
Refer as FCC KDB 558074, clause 12.2.5.1 Option 1 (trace averaging for duty cycle ≥98%)
Refer as FCC KDB 558074, clause 12.2.5.2 Option 2 (trace averaging + duty factor).
Refer as FCC KDB 558074, clause 12.2.5.3 Option 3 (Reduced VBW≥1/T).
Refer as ANSI C63.10, clause 4.2.3.2.3 (Reduced VBW). VBW ≥ 1/T, where T is pulse time.
Refer as ANSI C63.10, clause 4.2.3.2.4 average value of pulsed emissions.
Refer as FCC KDB 558074, clause 11.3 and 12.2.4 measurement procedure peak limit.
Refer as FCC KDB 558074, clause 12.2.3 measurement procedure Quasi-Peak limit.
For radiated measurement, refer as FCC KDB 558074, clause 12.2.7.
Refer as ANSI C63.10, clause 6.4 for radiated emissions below 30 MHz and test distance is 3m.
Refer as ANSI C63.10, clause 6.5 for radiated emissions 30 MHz to 1 GHz and test distance is 3m.
Refer as ANSI C63.10, clause 6.6 for radiated emissions above 1 GHz and test distance is 3m.
