10MHZ - 520MHz AM/FM Signal generator

Information

TF 2015 is a general purpose a.m./ f.m. signal Generator covering the frequency range 10 MHz to 520 MHz in eleven switched bands. Fundamental frequency generation is by voltage tuned oscillators which, in conjunction with the panel mounted controls, enable easy tuning to narrow band communication receivers up to the highest carrier frequencies.
