than 100 µs for any frequency change exceeding 2.2 GHz within the frequency range exceeding 4.8 GHz but not exceeding 31.8 GHz;
c. Not used;
d. Less than 500 µs for any frequency change exceeding 550 MHz within the frequency range exceeding 31.8 GHz but not exceeding 37 GHz; or
e. Less than 100 µs for any frequency change exceeding
2.2 GHz within the frequency range exceeding 37 GHz but not exceeding 75 GHz;
f. Not used;
g. Less than 100 μs for any frequency change exceeding 5.0 GHz within the frequency range exceeding 75 GHz but not exceeding 90 GHz;
3. A. 002. d. 4. A single sideband (SSB) phase noise, in dBc/Hz, specified as being any of the following:
a. Less (better) than –(126+20 log10F‑20 log10f) anywhere within the range of 10 Hz ≤ F≤ 10 kHz anywhere within the frequency range exceeding 3.2 GHz but not exceeding 90 GHz; or
b. Less (better) than –(206‑20 log10f) anywhere within the range of 10 kHz < F ≤ 100 kHz anywhere within the frequency range exceeding 3.2 GHz but not exceeding 90 GHz; or
              Technical Note:
              For the purposes of 3A002.d.4., F is the offset from the operating frequency in Hz and f is the operating frequency in MHz.
3. A. 002. d. 5. An 'RF modulation bandwidth' of digital baseband signals as specified by any of the following:
a. Exceeding 2.2 GHz within the frequency range exceeding 4.8 GHz but not exceeding 31.8 GHz;
b. Exceeding 550 MHz within the frequency range exceeding 31.8 GHz but not exceeding 37 GHz; or
c. Exceeding 2.2 GHz within the frequency range exceeding 37 GHz but not exceeding 75 GHz; or
d. Exceeding 5.0 GHz within the frequency range exceeding 75 GHz but not exceeding 90 GHz; or
Technical Note:
              For the purposes of 3A002.d.5., 'RF modulation bandwidth' is the Radio Frequency (RF) bandwidth occupied by a digitally encoded baseband signal modulated onto an RF signal. It is also referred to as information bandwidth or vector modulation bandwidth. I/Q digital modulation is the technical method for producing a vector-modulated RF output signal, and that output signal is typically specified as having an 'RF modulation bandwidth'.
3. A. 002. d. 6. A maximum frequency exceeding 90 GHz;
Note 1: For the purposes of 3A002.d., signal generators include arbitrary waveform and function generators.
Note 2: 3A002.d. does not apply to equipment in which the output frequency is either produced by the addition or subtraction of two or more crystal oscillator frequencies, or by an addition or subtraction followed by a multiplication of the result.
           Technical Notes:
              1. For the purposes of 3A002.d., the maximum frequency of an arbitrary waveform or function generator is
