The Extech 407790A-NIST Real-Time Octave Band Analyzer is an advanced and versatile instrument for comprehensive sound level analysis. This analyzer combines the capabilities of an auto-ranging Type 2 integrating sound level meter with real-time 1/1 and 1/3 Octave Band noise display and analysis.

The Extech 407790A offers five measurement parameters to provide a thorough assessment of sound levels. These parameters include SPL (Sound Pressure Level), Leq (Equivalent Continuous Sound Pressure Level), SEL (Sound Exposure Level), Lmax (Maximum Sound Pressure Level), and Lmin (Minimum Sound Pressure Level). This comprehensive set of parameters allows for detailed analysis and evaluation of sound levels.

With its built-in memory, the analyzer can store up to 12,280 data records in sound level mode and 1024 records in Octave mode. This allows for extensive data collection and monitoring over time. The stored data can be easily transferred to a PC using the 407790A software and USB cable, facilitating further analysis and reporting.

The Extech 407790A provides a choice of 'A', 'C', or Flat 'Z' weighting options, allowing for flexibility in selecting the frequency weighting that best suits the specific measurement requirements. The analyzer also offers different response times, including Slow, Fast, and Impulse, enabling the capture of sound characteristics in various scenarios.

In addition to its advanced measurement capabilities, the analyzer features AC and DC analog output signals. These outputs can be utilized to connect the analyzer to chart recorders and other external recording devices, providing options for real-time data visualization and further analysis. It includes NIST Certification.
