Description:
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.
