Common use of Test Requirements Clause in Contracts

Test Requirements. 4.1. The limits apply throughout the frequency range 30 to 1,000 MHz for measurements performed in an absorber lined shielded enclosure (ALSE) or open area test site (OATS). 4.2. Measurements can be performed with either quasi-peak or peak detectors. The limits given in paragraphs 6.5. and 7.10. of this Regulation are for quasi-peak detectors. If peak detectors are used a correction factor of 20 dB as defined in CISPR 12 shall be applied. 4.3. The measurements shall be performed with a spectrum analyser or a scanning receiver. The parameters to be used are defined in Table 1 and Table 2.

The parameters to be used are defined in Table 1 and Table 2. Spectrum analysers and FFT-based instruments, that meet the requirements of CISPR 16-1-1, may be used for conformity measurements. FFT-based measuring instruments shall continuously record and evaluate the signal during the measurement time. If using FFT-based instruments, the minimum measurement time shall be 1 s.
