Best Solution for LF Noise Measurement
Keysight E4727B (Advanced Low-Frequency Noise Analyzer; A-LFNA) allows you to measure the LF (Low Frequency) noise of semiconductor devices very easily. The E4727B consists of hardware and software. The user can measure LF noise by just entering the expected measurement conditions and the software will then set all parameters of hardware optimally. However, there are many challenges with LF noise measurement due to environmental noise surrounding the device under test. The noise source of environmental noise is mechanical machines, instruments, mobile phone antenna, grounding issues of the system, etc. It can be very difficult to find and isolate the specific root cause of the environmental noise. This Application Note shows tips on how to improve the environment noise for LF noise measurement. In addition, the powerful environmental noise remover “Auto Denoise” is introduced.
