The Agilent 8665A signal generator is suited for basic receiver testing up to 4.2 GHz.
With Option 004 (low-noise enhancement), it can be used for out-of-channel receiver testing or as a clock source where having the lowest phase jitter is important.
Radar testing can be done by adding Option 008 (pulse modulation) .
Pulse width and delay can be internally adjusted between 50 ns and 999 ns, eliminating the need for an external pulse generator.
Standard FM rates of up to 2 MHz and deviations to 20 MHz are suitable for many applications such as high-speed digital communications.

• < -140 dBc/Hz typical SSB phase noise at 20 kHz offset at 1 GHz with Option 004
  
• < -100 dBc nonharmonic spurious to 2 GHz reduces error when testing spurious immunity of receivers
  
• AM, FM, and optional pulse modulation
  
• 0.01 Hz frequency resolution
  
• On-site repair and calibration
