产品名称：合成信号发生器（英文版）

The Agilent 8642A synthesized signal generator is a high-performance, programmable signal generator for demanding out-of-channel RF receiver measurements and other stringent RF applications. It covers the frequency range from 100 kHz to 1057.5 MHz. This signal generator provides low SSB phase noise and spurious, high output level and level accuracy, and a full range of modulation types. The low-distortion internal modulation oscillator can be used to modulate the Agilent 8642A up to 100 kHz rates. This internal oscillator can also be used as an independent audio source with variable rates and levels.

Features
   *  < -134 dBc/Hz SSB phase noise at 20 kHz offsets at 1 GHz. 
   *  -100 dBc nonharmonic spurious allows spurious rejection tests to be fully automated with confidence 
   *  ±1 dB absolute output level accuracy down to -127 dBm 
   *  Up to +20 dBm output level reduces the need for external amplifiers 
   *  AM, FM, phase and pulse modulation 
   *  Up to 100 kHz modulationrates with low-distortion internal oscillator 
   *  On-site repair and calibration
