The AE-966 / AE-967 spectrum analysers cover a frequency band from 9 kHz to 3 GHz and allow a stable operation with span of 2 kHz/div to 3 GHz/div. The AE-966 is the basic model whereas the AE-967 includes a Tracking Generator, which turns the AE-967 into a highly useful tool for the response measurement of filters, amplifiers, attenuators and, generally speaking, any kind of radio frequency system. The plentiful measurement functions like markers, traces, power measurement, limit line, dual display and trigger make measurement more easily and quickly. The exit direct VGA is ideal to realize presentations. Includes USB interface to connect the spectrum analyser to a printer and a flash memory, and RS-232 interface to connect to a PC. The high resolution color TFT monitor allows a clear reading of the on-screen measurements.
