Permissible level of nonuniformity in the spectrum of test pulses when checking radio interference meters

Conclusions

• 1. With unilateral spectrum nonuniformities, we can permit a spectrum slope of 10%, which leads to a variation in the response amplitude of 0.1%.

• 2. With bilateral nonuniformities, the variation in amplitude and duration of response does not exceed 1% for short radio pulses, provided the spectrum is 10 times wider than the passband of the meter at the same level (or a duration of square wave radio pulse of less than O.1/F_IM0.5) and the meter operates at detuning frequencies at which the spectral density is not less than 0.7 of the maximum.

• 3. To conduct checks on the effect of overloading on the impulse characteristic, the spectrum of the short radio pulses must be not less than twice the passband of the scheme preceding the part in which overloading is possible.
