WebThe statistical properties of SNR are analyzed for chirped-pulse (CP-)OOTDR and compared with traditional OOTDR using coherent-detection. CP-OOTDR is showed to have drastically narrower (lower variance) SNR distribution, thus providing higher reliability measurements. © 2024 The Author (s) PDF Article More Like This WebLong-term drift, and the required tests connected with it, are specified in the EN 61298 standard. The long-term stability is defined in DIN 16086. How do long-term drift and long-term stability differ? With long-term drift, in accordance with EN 61298-2, chapter 7.2, a pressure value of 90 % of the measuring span must be maintained for 30 days.
