Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8657B #122598 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8657B is the successor to the well-known 8663A Sweep Oscillator family. It is a digitally synthesized signal generator that is designed to produce high accuracy CW signals over a wide range of frequencies from 9kHz to 2.9GHz. It is an excellent source for accurately calibrated test signals for testing radar systems, communication systems, audio equipment, and other applications requiring highly accurate carrier signals. HP 8657B is equipped with advanced digital calibration techniques that enable it to achieve RF and IF output power accuracy of up to ±0.2 dB. It also features Allan Deviation of ±3.2 x 10^-8 for its setting accuracy, which is unmatched in the industry. AGILENT 8657B also offers a wide choice of modulation formats. The traditional FM modulation allows for linear, constant peak-to-peak frequency excursion. As an additional modulation option, it includes Pulse Width Modulation (PWM). It enables to perform the traditional swept output operations over the full frequency range of the instrument. The PWM modulation also provides the ability to accurately control the amplitude and frequency of the output signal. It also supports vector modulation in both its I-Q and baseband formats. 8657B features three output ports, each of which has its own RF output level control (attenuator) to give the user full control over the signal power level. The output sine wave is also digitally filtered to minimize distortion associated with frequency-modulated signals. HEWLETT-PACKARD 8657B also provides an output power control loop that allows the user to offset the residual frequency drift of the signal. The digital filtering also enables the user to perform an exact frequency sweep. Another unique feature of KEYSIGHT 8657B is its integrated frequency-tracking digital down converter. Its fast acquisition time allows for accurate spectral measurements in a wide range of environments. The instrument also includes a 10MHz clock reference via a 10MHz coaxial Reference Input connector, which enables the user to synchronize multiple AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8657B signal generators for phase-triggered operation. HP 8657B signal generator provides superior performance and is ideal for testing, development and troubleshooting signal sources. Its advanced features, wide frequency range and accuracy, and signal power control make AGILENT 8657B a powerful and reliable signal generator for any RF signal application.
