Agilent / HP / Keysight 3585B

The Agilent/HP 3585B spectrum analyzer delivers high performance where it counts - at baseband frequencies.

The Agilent/HP 3585B with unmatched accuracy, resolution, and dynamic range, is the best solution for signal analysis at the critical frequencies comprising voice, picture, or digital information.

The HP 3585B provides 80-100 dB of spurious-free dynamic range, a sharp 3 Hz resolution bandwidth, and a 20 Hz - 40.1 MHz frequency range to easily cover most information bandwidths.

Fully synthesized tuning (including sweeps) and typical amplitude accuracy to ±0.25 dB are unique in this frequency range and ensure complete measurement confidence.

Measurement performance is critically important at baseband frequencies because signal degradation occurring here is typically not recoverable elsewhere in the system. As a result, test requirements for baseband signals and circuits often demand a level of performance that only a high-performance, low-frequency signal analyzer such as the 3585B can provide.

Well-designed filters and a phase-continuous, synthesized local oscillator team up with exceptional dynamic range to give the 3585B very fast measurement speeds.

With a single keystroke, the marker value can be entered as the center frequency, reference level, frequency span, or center frequency step size. This improves accuracy and efficiency in manual testing and reduces setup errors.

The built-in frequency counter provides additional accuracy when measuring the frequency of a signal in the display. Results are provided in 0.3 seconds to 0.1 Hz resolution. Because the counter function is combined with the selectivity of the analyzer, it is possible to accurately measure small signals in the vicinity of much larger ones.

Copying a complete display to a printer or plotter is as easy as pressing a button. The Agilent 3585B directly controls HP-GL compatible HP-IB plotters and graphics printers such as the HP Thinkjet printer.

The standard 50 tracking generator covers the full 40 MHz frequency range of the Agilent 3585B to provide easy scalar (amplitudeonly) network analysis. The signal is fully synthesized in CW measurements and sweeps and level is adjustable from 0 dBm to -11 dBm on the front panel.

The Agilent 3585B can directly replace the Agilent 3585A in virtually every application.

The Agilent 3585B meets all Agilent 3585A specifications and uses an expanded version of the Agilent 3585A programming codes.

Physical dimensions of the 3585A and 3585B are identical, and input and output are in the same location, serving the same functions.
