IEC 62368-1:2023 Annex E Pink Noise Generator

The LS8280 Pink Noise Generator is a signal analysis instrument developed based on computer multimedia technology. When used with computer control, it can function as a dual-channel signal generator, producing pink noise that complies with IEC 60065 Clauses 4.2 & 4.3 and IEC 62368-1:2023 Annex E (E.2.1), as well as sine wave noise specified in IEC 62368-1:2023 Annex E (E.2.2).

In addition, it is capable of generating a variety of other signals, including swept-frequency sine waves, swept-amplitude sine waves, sine wave bursts, white noise, narrowband white noise, and narrowband pink noise. These signals are widely applicable for verifying the electrical energy source classification of audio equipment, conducting tests under normal and abnormal operating conditions, and meeting the noise signal supply requirements of multiple scenarios such as household appliances, electronic musical instruments, and professional audio equipment.
