Thorlabs' PNA1 Intensity Noise Analyzer (INA) is a high-precision (18-Bit Analog-to-Digital Conversion) instrument used to measure intensity noise in optical systems. Featuring a DC to 3 MHz input frequency bandwidth, this device overlaps data from several sample rates to optimize resolution bandwidth and provide high frequency-axis resolution over its full bandwidth; the 9 Hz minimum resolution bandwidth is ideal for resolving low-frequency noise sources. With a nominal noise floor less than -140 dBV^2/Hz, this low-noise instrument is designed to identify environmental noise sources, such as ambient lighting or electrical line noise, in an optical experiment. Ideal applications also include light source and instrumentation development, where characterizing noise levels or detection limits is critical. To provide high frequency-axis resolution at low frequencies, data acquisition occurs at three separate sample rates: 12.5 MHz, 781.25 kHz, and 48.83 kHz.
