Agilent / HP 3585B

If you are looking for a high performance spectrum analyzer with tracking in the 20 Hz to 40 MHz range, the HP 3585B gives you world class performance with the value and confidence that come with the AccuSource 16-step quality assurance process.

• 80 to 100 dB dynamic range
• ± 0.25 dB typical level accuracy
• 50, 75, 1 MÙ  inputs
• 3 Hz resolution bandwidth
• Automatic limit testing

Uncompromising Baseband Signal Analysis

The Hewlett Packard 3585B Spectrum Analyzer delivers high performance at the critical frequencies comprising voice, video, or digital information. With very high accuracy, resolution, and dynamic range, the HP 3585B is a top performer.

In today's high-speed, high-density information processing systems, maintaining the integrity of data signals requires more measurement performance than ever before.  The HP 3585B provides 80 to 100 dB of spurious-free dynamic range, a sharp 3 Hz resolution bandwidth, and a 20 Hz to 40.1 MHz frequency range to easily cover most information bandwidths.  Fully synthesized tuning (including sweeps) and typical amplitude accuracy to ± 0.25 dB ensure complete measurement confidence.

 Carefully Chosen Features for Better Measurements

Measurements are faster and easier with the optimized feature set.  The automatic limit test function checks all 1000 measurement points against user-defined upper and lower limits in a fraction of a second.  Pass/fail results are shown in the display and are available over HP-IB for improved productivity in automated applications.

The automatic peak search and signal track functions speed signal identification and analysis and make examination of drifting signals more convenient.  In addition to locating the strongest signal in a display, the peak search function can also find successively smaller signals, or search to the right or left for peaks above a user-defined threshold.

Fast, Flexible Frequency Sweeps

for high-resolution spectrum surveillance. A 1 MHz seep using a 1 kHz bandwidth takes only 2 seconds, yet yields an average noise floor of -85 dBc.
