The key component in an RF and microwave calibration system

The Fluke 9640A and 9640A-LPNX RF Reference Sources are designed specifically for RF calibration (including spectrum analyzer calibration, network analyzer calibration, attenuator calibration, and more), featuring a calibration-oriented user interface, precision signal level and attenuation, high signal purity and precision low distortion modulation. This unique combination of features and performance makes them clearly superior to the general purpose signal generators that are often used in RF calibration systems, with the 9604A-LPNX low phase noise version providing superior phase noise performance.

 

The 9640A Series simplifies and speeds up calibration procedures, reduces opportunities for operator errors, and greatly simplifies RF metrology. As the core of an RF and microwave calibration system, the 9640A Series covers the majority of test points required for calibrating spectrum analyzers of any frequency range.

 

Used manually or automated with MET/CAL® Plus Calibration Management Software, the 9640A rf reference reduces complexity and calibration times, dramatically improving efficiency and increasing capacity. Walk-away automation with the 9640A Series performing the majority of tests enables operators to carry out additional value-adding tasks rather than wasting time waiting for frequent system setup changes.

 

What’s new?

New features included in the 9640A Series:

  • 9640A-LPNX model improved phase noise
    Reduced close-in phase noise and specifications to 1 Hz offsets.

  • Improved level accuracy and attenuation
    Specifications for better test uncertainty ratios against the most demanding workloads.

  • Optional integrated 50 MHz frequency counter
    Reducing the number of instruments needed in an RF calibration system in the lab or onsite for UUT frequency reference testing.
