8444A頻譜分析儀的簡(jiǎn)單介紹: Agilent/HP 8444A Agilent/HP 8444A - 500Hz-1.5GHz 跟蹤源 8444A頻譜分析儀的詳細(xì)資料: Description: The Agilent HP 8444A is a refurbished Tracking Generator. Other Info: The HP Agilent 8444A is a tracking signal source for use with the 8554B and 8555A Spectrum Analyzers. The HP 8444A provides a swept source for frequency response measurements, and a constant amplitude signal for a frequency counter input. The HP 8444A allows for swept frequency tests over the 500kHz to 1250MHz frequency range. Dynamic range is greater than 90 dB from spectrum analyzer 1 dB gain compression point to average noise level (approx. -10 dBm to 100 dBm).
