The HP / Agilent 8644A signal generator has been optimized to provide the performance required for out-of-channel receiver tests while maintaining a low price.
8644A Reliability is enhanced by an electronic attenuator on the 1 GHz version. Instead of mechanical relays, the 8644A uses solid state components accurate to within 1.0 dB for setting levels.
An advanced internal modulation synthesizer provides coverage to 400 kHz and two-tone capability with the selection of sine, square, triangle, sawtooth, and white Gaussian noise waveforms. The 8644A operates from 252 kHz to 1030 MHz (2060 MHz with option 002).
