Hewlett-Packard / Agilent Technologies, High-Performance Signal Generator, 1 GHz or 2 GHz (8644B)

The Agilent 8644B signal generator represents the highest overall performance in Agilent's line of 1 GHz and 2 GHz signal generators. This generator has very low SSB phase noise (-136 dBc/Hz) and spurious (-105 dBc). Instead of mechanical relays, the Agilent 8644B 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.

• -136 dBc/Hz SSB phase noise at 20 kHz offset at 1 GHz
• < -105 dBc nonharmonic spurious up to 1 GHz allows spurious rejection tests to be fully automated with confidence
• ±1.0 dB output level accuracy down to -127 dBm
• Internal modulation synthesizer with coverage up to 400 kHz and two-tone capability
