IMPORTANT NOTICE: This standard is not intended to ensure safety, security, health, or environmental protection in all circumstances. Implementers of the standard are responsible for determining appropriate safety, security, environmental, and health practices or regulatory requirements.

Normative references The following referenced documents are indispensable for the application of this standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies.

Basic instrumentation Required instrument characteristics are summarized in Table 1.
3. US National deviations to CISPR 16-1-1:2003 3.1 Frequency ranges In this standard, the starting frequency is 10 Hz, with upper frequency of 40 GHz. This edition has changed the starting frequency in band b), as listed in Clause 5 of ANSI C63.2-1996, 3 from 10 kHz to 9 kHz, to harmonize with international and US Federal Communication Commission (FCC) requirements. The existing requirements for the low-frequency band, from 10 Hz to 20 kHz (as specified in ANSI C63.2-1996, Clause 5 and Figure 1), shall be maintained. The characteristics in this range are the same as shown in Clause 9 of CISPR 16-1-1:2003. 3.2 RF sensitivity Per ANSI C63.2-1996 (Table 1 and Clause 6) the RF sensitivity (S/N = 2 dB) of the field strength instrumentation shall be 0.01 μV for 10 Hz to 20 kHz, 0.5 μV for 9 kHz to 1000 MHz, and 2.2 μV to 3 μV for 1 GHz to 40 GHz. CISPR 16-1-1 has no requirements for RF sensitivity. The VSWR is specified in CISPR 16-1-1:2003 (Clause 4) to be 2:1 without any attenuation, and 1.2:1 with 10 dB of attenuation. As was also specified in ANSI C63.2-1996, for this standard VSWR shall be less than 3:1 below 1 GHz, and less than 2:1 above 1 GHz.
3.4 Calibrator ANSI C63.2-1996 (4.3 and Table 1) specified that either an impulse or a sine-wave calibrator may be used to amplitude calibrate the instrumentation; 4.3 of CISPR 16-1-1:2003 has a requirement for sine-wave calibration. 3.5 Spurious-free dynamic range ANSI C63.2-1996 (Clause 9 and Table 1) required that the spurious-free dynamic range shall be 60 dB at the minimum bandwidth and in the peak detector mode; 4.5 of CISPR 16-1-1:2003 requires only 40 dB. 3.6 RF dynamic range or overload factor ANSI C63.2-1996 (Table 1) required that the RF dynamic range shall be 80 dB at the minimum bandwidth and in the peak detector mode; 4.2 of CISPR 16-1-1:2003 uses the term Overload Factor and has values between 24 dB and 43.5 dB for circuits preceding the detector. 3.7 Detector integrating time constant for rms and average detector ANSI C63.2-1996 (10.3 and Table 1) required that a variable detector integrating time constant shall be provided that is variable from 0.1 s to 100 s. Because no commercial or military specification exists that requires a variable integrating time constant, therefore this requirement was deleted for this edition; CISPR 16-1-1:2003 has no requirement for a variable integrating time constant.
