Test holders should give the same V.S.W.R. as the standard holders within 2 %. NOTE 2Mixer diodes shall not be used as standards
32、 for measurement of any parameter but may be used as transfer standards. The standard admittance shall be defined by holders supplied by the Approving Authority. NOTE 3The standard reference shall be a noise tube VX9247, assuming a noise level of 15.3 0.1 dB above thermal for a current of 200 mA. An
33、y approved method of measurement may be used, with allowance for experimental error. NOTE 4The standard of reference shall be a RC 7 k resistor within the range 330390 ohms, mounted axially in a holder having the same socket dimensions as a CV7771, with lead lengths less than 0.125 inch. The resista
34、nce shall be assumed equal to the d.c. value. The limit may be increased to 550 ohms if an approved bridge method is used. NOTE 5%Fo may be greater than 1 dB if (Fo+ %Fo) is less than, or equal to, 7.5 dB. %Fo must not be greater than 1 dB if (Fo+ %Fo) is greater than 7.5 dB. NOTE 6The diode shall b
