8565E Agilent Spectrum Analyzer


The 8565E is a 50 GHz Spectrum Analyzer from Agilent. A spectrum analyzer measures the power of spectrums of known and unknown signals. Spectrum analyzers collect information such as the magnitude of an input signal compared to its frequency. As a frequency analyzer, spectrum analyzers’ main use is to document and analyze electrical input signals as well as spectral compositions of other signals.

Additional Features:

  • Continuous 30 Hz to 50 GHz sweep
  • Fast digital resolution bandwidths of 1, 3, 10, 30 and 100 Hz
  • Adjacent channel power, channel power, carrier power, occupied bandwidth percentage and time-gated measurements standard
  • Precision timebase and 1 Hz counter resolution
  • MIL-T-28800 rugged
  • Measurement personalities for digital radio and phase noise measurements

The Agilent 8565E portable millimeter spectrum analyzer offers the measurement capability and performance previously found in larger, more expensive benchtop analyzers. You can measure signals from 30 Hz to 50 GHz (preselected above 2.75 GHz) with a single coaxial connection.

The 8565E combines outstanding phase noise, sensitivity, 1 Hz resolution bandwidths, synthesized tuning and wide dynamic range in a MIL-rugged package built to withstand harsh environmental conditions. It offers a complete solution for adjacent-channel power (ACP) testing of burst carrier signals using digital modulation, and the ability to measure occupied bandwidth percentage.

Using the Agilent 11974 series millimeter mixers, preselected coverage reaches 75 GHz, and with other mixers, un-preselected coverage can be extended higher.

The units meet all MIL-T-28800 requirements, including those for temperature, pulse shock, and transit drop. The analyzer fully meets specifications at temperatures from - 10 degrees to + 55 degrees Celsius and they can withstand 30 g's of shock.

These spectrum analyzers are optimized for high-performance measurement applications. Key specifications include Phase noise of -113 dBc/Hz at 10 kHz offset from the carrier, 100 db of third order dynamic range, -144 dBm sensitivity at 1 GHz, in a 1 Hz RBW. An image enhanced harmonic mixer extends excellent performance into the microwave frequencies in the HP 8563E.

Fast Digital Resolution Bandwidths
Digitally implemented resolution bandwidths of 1, 3, 10, 30 and 100 Hz allow these spectrum analyzers to weep from 3 to 600 times faster than is possible with comparable analog filters. A narrow 5:1 shape factor allows you to view close-in, low-level signals easily. Digital bandwidth also provides the unit with a full 100 dB onscreen calibrated display.

Digitized, Fast Time Domain Sweeps
Add digitization to fast time domain (zero span) sweeps with Option 007. Use markers, trace math, trace storage and get hardcopy output for measurements such as rise/fall times, pulse widths, and time between events.

Frequency Accuracy
A precision frequency reference is standard. At 1 GHz, it provides a frequency accuracy of plus or minus 135 Hz after a 15-minute warmup.

Adjacent Channel Power, Occupied Bandwidth, and Gated Video
Built-in keys for ACP and occupied bandwidth measurements give you results quickly for these common measurements on communication systems. Time-gated signal analysis is another feature that allows you to easily measure time-varying signals such as pulsed RF, time domain multiple access, interleaved, and burst modulated. The 85902A burst carrier trigger can supply a TTL trigger signal.

Specified Pulse Response
These portables easily capture and accurately display short duration radar pulses. Specified pulse digitization uncertainty is plus or minus 1.25 dB and typical repeatability is 0.2 db.

Scalar Network Analysis Capability
The 85644A and 85645A tracking sources allow the series to make high performance scalar network anaylsis measurements at up to 6.5 or 26.5 GHz.

The 85620A plug-in module adds measurement personality capability, enough memory to store 100 traces, memory card capability, and computer capability without an external controller. Create complex measurement routines and save them as single key measurements stored on memory cards or in the module's battery backed RAM.
