The SA-3052 is a microprocessor controlled, one-third octave, real time spectrum analyzer. It is affordable, rugged, reliable, easy to use, fast to setup, and designed and manufactured by audio enthusiasts who have been building spectrum analyzers for twenty years. This is a true professional instrument at a very favorable price which has made this family of analyzers the world’s most popular.

The SA-3052 comes with a complete range of features including pink noise generator, calibrated microphone, memories, SPL functions, ability to average memories, peak hold utilities, comprehensive manual, and large, easy to read display. The SA-3052 is very portable since it also contains an internal battery pack and smart charger as standard equipment.

Results are easy and quick to achieve since the SA-3052 is a completely self-contained, stand alone device which do not need a computer to operate. The time from turn on to making measurements is less than three seconds. There is no training necessary.

With its all-metal construction and very rugged design, this is an honest product that will last, and be accurate, for many years to come.

The battery pack allows the SA-3052 to operate without connection to AC mains supply. The gel cell battery supply has sufficient capacity to operate the unit continuously for about 4 hours. An internal smart battery charger functions when the SA-3052 is plugged into AC and automatically adjusts the rate of charge. The power LED on the front panel glows red when the unit is charging its batteries and flashes as full charge is reached.
