Fluke 9640A RF Reference Source 4 GHz RF Calibration

$8,409.00Price
  • The Fluke 9640A Reference Source can help you simplify the RF calibration process. The 9640A can help calibrate a broad range of RF test equipment: Spectrum analyzers, Modulation meters and analyzers, RF power meters and sensors, Measurement receivers, Frequency counters, Attenuators, and more.

    The Fluke 9640A Reference Source features a unique combination of level accuracy, dynamic range and 4 GHz frequency capability to calibrate the broadest range of RF measurement workload. It has been designed specifically for metrology applications where the combination of level accuracy and dynamic range is important.

    The 9640A Reference Source’s internal modulation capability makes it suitable for applications that require precision modulation to be applied to the output signal, such as modulation analyzer calibration. You don’t need additional function generators as a low frequency modulation source – the 9640A delivers it all. Frequency modulation is available at rates up to 300 kHz for applications such as modulation analyzer testing. Amplitude modulation is available at depths of up to 99 % and rates up to 200 kHz.
