Siglent's SSA3032X Spectrum Analyzer covers signals in the 9 KHz - 3.2 GHz variety and determines the magnitude of an input signal versus frequency over the complete frequency series of the instrument. It is ideal for measuring the power of the spectrum of both understood and unidentified signals. Examining electrical signal spectra helps define wireless transmitters or other electronic devices, identifying dominant frequency, power, distortion, harmonics, bandwidth, and other spectral parts of a signal that are not easily detected in time domain displays. The SSA3032X Spectrum Analyzer is light weight (10lb) and little size (15.5" x 8.2" x 4.6"), with an easy to use user interface on a big 10.1" TFT LCD. It features 256MB of internal storage memory, with approximately 32GB supported externally through the USB port.
