Used KEYSIGHT 8656A #9126893 for sale

KEYSIGHT 8656A is a microwave synthesized signal generator that provides a precise, versatile, and reliable source of digital modulated signals for use in a variety of applications. It is characterized by ultra-low phase noise and wide dynamic range, making it suitable for use in a variety of RF test applications such as radio communication, radar simulation, and radio astronomy. 8656A utilizes a 10 MHz sine wave from a 1 GHz oven-controlled crystal oscillator (OCXO) as its source for syntheses. It is a direct digital synthesizer (DDS) that synthesizes the tuned frequency by taking in a 10 MHz reference to determine the desired frequency. It has two sources - an internal reference oscillator (where a user-programmable 10 MHz reference loop can be programmed to allow an improvement of phase noise) and an external reference oscillator. KEYSIGHT 8656A has a frequency range of 9 kHz to 1 GHz with a resolution up to 1 µHz and a frequency accuracy of 1 ppm. It also has a standard FM generation of 15 kHz. For signal output, the synthesizers include a true AM modulation that can offer both low-level and high-level outputs. 8656A has an adjustable RF output power that ranges from -130 dBm to +10 dBm. It has a high level of RF power stability with only 0.1 dB change over a period of eight hours, making it ideal for applications requiring a continuously tuned signal. KEYSIGHT 8656A has a Spurious- Free Dynamic Range (SFDR) of better than 60 dB at 1 GHz. It also has an internal IQ modulation that can combine two I and Q inputs for producing either a single or dual-frequency signal. 8656A has a number of standard analog and digital interfaces for external control, and it is also controllable from a general-purpose converter that comes with the synthesizers. KEYSIGHT 8656A can be used in laboratory-based applications such as radar simulation, radio communication, and radio astronomy. It is an ideal choice for users who require a versatile, reliable source of digital modulated signals.
