The HP 8654B Signal Generator is a portable, solid-state RF source providing calibrated and leveled signals from 10 to 520 MHz, and from +10 to —130 dBm. An internal oscillator provides calibrated amplitude and frequency modulation at 400 and 1000 Hz. Calibrated modulation from an external source is also possible. A front-panel meter indicates output level, percent AM, or FM peak frequency deviation.
