The HP 8642A synthesized signal generator is a high performance programmable signal generator intended for the most demanding out-of-channel RF receiver measurements and other stringent RF applications. It provides state-of-the-art SSB phase noise at 20 kHz offsets of -134 dBc/ Hz at 1 GHz. Nonharmonic spurious are held to below -100 dBc on the HP 8642A up to 1 GHz and to below -94 dBc above 1 GHz. This generator allows receiver spurious rejection tests to be fully automated with the utmost confidence in test results. In addition to a high-reliability attenuator, absolute output level accuracy is ±1 dB down to -127 dBm (0.1 uV) . The HP 8642A offers AM, FM, M and pulse modulation across their full frequency ranges. A low distortion internal modulation oscillator can be used to modulate the HP 8642A up to 100 kHz rates. The internal audio oscillator can also be used as a stand-alone audio source with variable rates and levels. Frequency Range: 100 kHz to 1057.5 MHz. Resolution: 1 Hz, 0.1 Hz with special function. Output Level range: from maximum available to -140 dBm (0.023 uV). Resolution: 0.1 dB. Absolute accuracy: ±1 dB, output level >= -127 dBm. Flatness: <= ±0.75 dB, +10 dBm output level. Opt 001 High stability time base. Opt 002 Input/output connectors on rear panel only.
