The Agilent/Keysight 8654B is a solid-state RF signal generator delivering precise signals from 10 Hz to 520 MHz. It generates stable output across a dynamic range of +10 dBm to −130 dBm (0.7 V to 0.07 µV), enabling receiver sensitivity measurements down to 0.1 µV with 0.1 dB resolution. The instrument supports both internal and external modulation—AM and FM with calibrated sources at 400 Hz and 1000 Hz, plus fully calibrated FM deviation control. A front-panel analog meter displays output level, AM percentage, or FM peak frequency deviation in real time.
