(iii) An integrated phase noise better than -60 dBc/Hz referred to a 30 kHz band centred on the carrier and excluding the 1 Hz band centred on this carrier; or
(iv) An integrated AM phase noise better than -70 dBc/Hz referred to a 30 kHz band centred on the carrier and excluding the 1 Hz band centred on this carrier;
Note: Synthesized signal generators which are embargoed only by (b)(1) or (b)(2)(i) above may be exported up to a maximum synthesized output frequency of 1,400 MHz or down to a single sideband phase noise of -136 dBc/Hz when measured at an offset of 20 kHz from a carrier frequency of 100 MHz, provided the technology supplied is only the minimum necessary for the use (i.e., installation, operation, and maintenance) of such generators.
(3) Electrically programmable in frequency (in that the output frequency can be controlled or selected by the injection of digitally coded electrical signals from an external control source) with a "frequency switching time" of less than 10 milliseconds;
(4) Electrically programmable in phase (in that the phase of the output frequency can be varied relative to the internal or external reference standard, or selected in accordance with an externally supplied code or signal with a switching speed from one selected phase value to another of less than 10 milliseconds) except those equipments incorporating pre-emphasis networks for frequency modulation;
(5) Having a level of spurious components in the output, measured relative to the selected output frequency better than:
(i) –60 dB harmonic or
(ii) -92 dB non-harmonic;
(6) Having more than three different selected synthesized output frequencies available simultaneously from one or more outputs;
(7) With facilities for pulse modulation of the output frequency;
(c) Airborne communication equipment using "frequency synthesizers", as follows, and specially designed components and accessories therefor:
(1) Designed to receive or transmit frequencies greater than 156 MHz,
(2) Incorporating facilities for the rapid selection of more than 200 channels per equipment, except those equipments operating in the frequency range of 108 to 136 MHz incorporating facilities for the rapid selection of 720 channels or fewer at not less than 25 kHz channel spacing, which have been in normal civil use for at least one year;
(3) With a "frequency switching time" of less than 10 milliseconds;
(4) "Frequency synthesizers", designed for the above equipment, whether supplied separately or with the said equipment, exceeding the parameters specified in (b) above:
Note:
See also Item IL 1501(a).
(d) Digitally-controlled radio receivers, whether or not computer-controlled which search or scan automatically a part of the electromagnetic spectrum, using "frequency synthesizers", as follows, and specially designed components and accessories therefor:
(1) Digitally-controlled receivers in which the switching operation takes less than 10 milliseconds, except non-ruggedized digitally-controlled preset type radio receivers designed for use in civil communications, which have 200 selective channels or fewer;
(2) "Frequency synthesizers" designed for the above equipment, whether supplied separately or with the said equipment, exceeding the parameters specified in (b) above, except those specially designed for receivers freed from embargo under (d)(1) above;
