The HP / Agilent 11715A AM/FM Test Source is a tunable voltage-controlled oscillator combined with modulators to form a source of calibration-quality amplitude and frequency modulated signals. It is designed primarily to verify the demodulation performance of the Agilent 8901A
Modulation Analyzer, but its excellent signal qualities
can benefit many other demanding applications.
The 11715A front panel provides four separate RF outputs
with both fixed and variable carrier frequencies and an input for a modulation source. The fixed output is a crystal-derived 560 MHz carrier with low residual FM. The other three output ports cover 11 to 13.5 MHz, 88 to 108 MHz, and 352 to 432 MHz. Frequency modulation is possible on all
three ranges, and amplitude modulation is available on the 11 to 13.5 MHz range.
