Industry’s Best Close-To-Carrier Phase Noise Performance

The E8663B analog signal generator provides the industry’s lowest close-to-carrier phase noise available in an off-the-shelf signal generator. With included analog modulation (AM, FM, ØM, and pulse) capability, superior level accuracy and high output power, the E8663B is the right choice for demanding applications such as radar system development, satellite communications evaluation, or when a very low noise local oscillator or reference signal is needed. Built on the outstanding legacy of the 8663A, the E8663B delivers improved performance and is fully code compatible with its predecessor for seamless upgrades to existing test systems. Enhanced narrow pulse modulation and extended support life are optionally available.

Signal Characteristics

  • 100 kHz to 3.2 or 9 GHz with .001 Hz resolution
  • -135 to +18 dBm typical output power
  • Provides the best close-to-carrier phase noise and specified down to 1 Hz offset from carrier


  • AM, FM, ØM, and pulse (may be simultaneously enabled)
  • Typical 8 ns rise/fall times and 20 ns pulse width from 10 MHz to 9 GHz
  • Dual internal function generators: sine, square, triangular, ramp, and noise

Automation and Communication Interface

  • 10BaseT LAN and GPIB
  • SCPI and IVI-COM drivers
  • Backwards compatible with the 8662A and 8663A signal generators
  • Compatible with the E5500 and 3048A phase noise test systems
