Most cable companies and the networking companies use this piece of equipment to find out the frequency at which the network will work. This equipment also helps to determine the strength of the signal. There are various other parameters that need to be checked once the installation has been done. Other industries which use analyzers are the Satellite TV companies as well as the two-way radio companies.
The tradition spectrum analyzers are very large and bulky. They are used by large cable corporations when they install a new cable network in the area. These analyzers can be used to detect the spectrum frequency and tune the network accordingly. This is true when you are at the initial stages of installing a network.
Now when the network has to be tuned at the last stage of the installation in an office of home then these bulky spectrum analyzers just cannot work. There is then the need for much better alternatives which the installation engineer can take with him into the home where he is installing the cable.
This is done with the help of the handheld spectrum analyzers. These handheld ones are of course not that accurate as the stationary ones. However these are needed to accurately predict the network availability in the case of the installation at home and offices.
There are a large number of companies that manufactures these and these companies also give on lease or rent. There are various ways that they rent beginning from weekly basis to a monthly basis.
