The 3585A Spectrum Analyzer with a fully synthesized local oscillator and HP-IB controllable. Outstanding low frequency performance from 20Hz to 40.1MHz. Within 0.4 dB overall measurement accuracy is maintained by an internal calibration routine, performed by an internal microprocessor.

The 3585A is a microcomputer-controlled Spectrum Analyzer operating from 20 Hz to 40.1 MHz. The 3585A features 0.1 Hz frequency settability, resolution bandwidths of 3 Hz to 30 kHz in a 1-3-10 sequence, and an amplitude measurement range from -137 dBm to +30 dBm (50 or 75 ohms) or 31 nV to 22 V (1 Mohm).

Quiet and rock-stable, the HP 3585A excels as a noise and distortion analyzer. Its own uncompromising sensitivity and spectral purity are assured by its advanced front end design, synthesized local oscillator and built-in, oven-stabilized reference.

2014年9月18日 · There isn't much at all different in their features or operation other than a few upgraded specs on the B model. The biggest difference is processing speed. Like the 856X analyzers this model got a processor enhancement with the B suffix (HP custom processor to Motorola if the same as the 856X analyzers) that speeds it up.

The HP 3585A is a 20 Hz to 40.1 MHz, microcomputer controlled spectrum analyzer. It may be utilized for spectrum analysis or network analysis (amplitude only) applications. As a spectrum analyzer, the 3585A provides a graphic display of the spectral components of the input signal.

The HP 3585A Spectrum Analyzer has a frequency range of 20 Hz to 40.1 MHz and the measuring range from -137 dBm to +30 dBm. Center frequency and span settings have 0.1 Hz resolution and ± 1 x 10-7/month stability over its entire operating range.

2008年4月17日 · 最近通过快递进了一台HP3585A 20HZ-40MHZ的频谱仪.频谱曲线形状能正常显示出来.但经常出现CAL ERR 07代码错误,测量的电压幅值不正确.到现在还没解决. 刚到手时,频谱曲线能显示出来,但已经常出现CAL ERR 07代码错误,仪器屏幕显示的字符也不正常.经过把电路板拆下,清理了他的PCB插口 (俗称金手指),字符显示也不正常的问题得到解决.这仪器按数字编号的PCB板达到70多块 (实际应该有50多块),就这个清理,足足花了两天.晕...........

The HP 3585A Spectrum Analyzer delivers high performance where it counts – at baseband frequencies. With unmatched accuracy, resolution, and dynamic range, the 3585A is HP’s best solution for signal analysis at the critical frequencies comprising voice, picture, or …
