Keysight (Agilent) 8561B 6.5GHz Spectrum Analyser Description:

  • 50Hz - 6.5GHz frequency range
  • -131dBm noise floor
  • 10Hz - 2MHz RBW
  • Portable and ruggerised
  • High performance synthesized

The Agilent 8561B is a member of the 856xx range of portable spectrum analyzers. The HP 8560A and 8561B offer excellent performance for RF design and service applications. The HP 8560A has a frequency range of 50 Hz to 2.9 GHz and the HP 8561B extends this range up to 6.5 GHz. Both have synthesized tuning for drift-free, accurate measurements. They also have sensitivity of -130 dBm and digital bandwidths of 10, 30, and 100 Hz. Both analyzers meet MIL-T- 28800C specifications for ruggedness.

Manual control is simple with an easy-to-use combination of hardkeys and softkeys that minimizes the number of keystrokes required to make measurements. Other measurement features include advanced marker capability and built-in AM and FM demodulators.

Hardcopies of results are easily obtained using the analyzers direct print and plot functions or by using a computer.

Scalar measurement capability is available by adding an optional built-in tracking generator to the HP 8560A or by using the HP 85640A portable tracking generator with either analyzer. For millimeter applications that dont require full microwave coverage, the HP 8560A and 8561B provide lower cost solutions. Both are compatible with HP 11970 series harmonic mixers and HP 11974 series preselected millimeter mixers. For very precise measurements, consider an optional precision frequency reference. It gives frequency accuracy of 150 Hz at 1 GHz.

The HP 8562A and 8563A extend the features and capabilities of the RF members of the HP 8560 series into the microwave frequency range. In addition, both the HP 8562A and the HP 8563A have standard, preselected frequency ranges of 9 kHz to 22 GHz that can be extended to 26.5 GHz with option 026. Their internal preselector requires no adjustment after 30 minutes at room temperature. This means faster measurements, which can be especially important in automated testing. For millimeter-wave measurements, preselection can be extended to 75 GHz using the HP 11974 series millimeter mixers.

Unpreselected frequency range can be extended to 110 GHz using the HP 11970A series mixers and to 325 GHz using mixers from other manufacturers.

The HP 8562A has sensitivity of -110 dBm. The HP 8563A has sensitivity of -120 dBm and digital resolution bandwidths of 10, 30, and 100 Hz. The HP 8563A also features 128 Kbytes of battery backed RAM that stores up to 100 traces and states, limit-line capability for defining test criteria and a built-in clock/calendar for stamping traces and other output data. (These features can be added to the HP 8562A with the mass memory module accessory.).

We offer the refurbished used Keysight (Agilent) 8561B 6.5GHz Spectrum Analyser for sale and rental.

The Keysight 8561B is fully tested and refurbished in our in-house ISO9001 calibration laboratory. We supply manuals, accessories, full warranty and a free-of-charge Certificate of Conformity. We can also provide the Keysight 8561B with a fresh calibration for a small additional charge.

If you have under-utilised test equipment talk to us about trading-in or part-exchanging it towards the Keysight 8561B or other refurbished test equipment.
