The spectrum analyzer program goes from 0 decibels to 180 db in 10 db selectable choices and 1 db per division visual resolution and 0.1 db decibel resolution. Microphone Frequency Range is extremely wide, from: 5(five)hertz to 20,000 hertz. spectrum analyzer sound level meter is from 10 hertz to 50,000hertz and your choice; selectable 1 octave,1/3, 1/6, 1/12 to 1/24 octave resolution!!! It also has single individual spectral line focus highlighting with frequency and decibel data. It also has time averaging and manual or automatic selectable computer speed resolutions to optimize your computer for best possible performance.
It will also play music that is coming from your own computer music files or C.D.'S so you can "see" your favorite song!
all you need is a computer or laptop.

It has an input reading range from 0.00001 volts to 5.000 volts if you just want to plug in an outside source like an ipod music player to see music or some other voltage input source or even a digital source. It also has memory, sound decibel level, peak, hold, frequency generator and output amplitude functions. It also has in internal and external voltage calibrator. The oscilloscope reads from 0.001 volts per division to 5 volts per division and 0.05 millseconds to 200 milliseconds per division.
You can also use the microphone only for only sound level decibels with an ordinary MULTIMETER digital kind that reads MILLIvolts.
The microphone can also work by just connecting the normal ipod size 1/8 inch mini plug to any devise that reads voltage, like an ocilloscope, spectrum signal analyzer, and THATS IT!
Comes with , computer software#1 and #2 spectrum analyzer with oscilloscope function, info disk, calibration chart, owner certificate. A stereo testing audio C.D. disk is also added for FREE.
