Scientists and engineers need a spectrum analyzer in order to study wavelengths. These machines are expensive and if the person doesn’t have one, the best thing to do will be to a refurbished unit that is much cheaper.

The individual may find one in the junk shop and then replace the old parts with those that can be bought in Radio Shack. However, there is another way to do such studies without spending so much on equipment.

The person can do this by downloading the software in the computer. If the engineer has a laptop or a desktop at home and is using a Windows as an operating system, a program that will work is the Spectrogram 14 that has a heads up display showing everything in the monitor.

This can be used to analyze video and audio files that are stored in the computer’s hard drive. An amateur video director can even use this to edit the film before showing the final product.

Another good choice is the Oscillometer that is known by some as the Spectrum Analyzer 4.14. It has other things that appear on the display, which is why it will cost a little over $400, but this will still be cheaper than getting a brand new spectrum analyzer that could occupy a lot of space in the office.

Sometimes, the sound engineer has to bring some work home. Another program that can be downloaded into the computer is the Spectra Scope, which allows the user to listen to up to four tracks simultaneously or one by one.

For those that are skeptic about what this program can do, the individual can sign up for a free trial for just $30 and if happy, the customer can purchase the entire package later on.

People who can’t afford to spend something above a hundred dollars and are unsure if something free can work can try the TrueTRA that can be bought for less than $40. It also has the different meters to analyze wavelengths just like the others.

Buying a refurbished spectrum analyzer is like buying a second hand car that has to be put together for it to be up and running again. The individual may not have the time to get the parts one by one so downloading this for free or buying a copy of the program at an affordable price seems to be the better option to get the job done.
