The Aeroflex Wichita Division in Wichita, Kan., released an RF spectrum analyzer option for the 3500 handheld 1 GHz radio test set. Using an advanced fast Fourier transform (FFT) algorithm, the 3500 spectrum analyzer option provides an almost instantaneous display of the RF frequency spectrum. The 3500 measures signal levels down to -136 dB. The unit weighs less than 8.5 pounds. The 3500 spectrum analyzer spans ranges of 10 kHz to 5 MHz and an effective resolution bandwidth as small as 19 Hz. Marker functions are available for the user to measure power in a specified bandwidth. Based on a rugged design that has been approved by the U. S. military, the 3500 offers a wide range of RF test and analysis tools.
