The R&S FSUP26 Signal Source Analyzer combines the functionality of a high performance spectrum and signal analyzer with the advantages of a phase noise test system, all in a single box. The R&S FSUP26 is a unique and simple-to-use one-box solution for measuring oscillators and synthesizers in development and production applications. In addition, the Rohde & Schwarz FSUP26 leads to enormous cost reductions.
The Rohde and Schwarz FSUP26 analyzer is perfect for not only modern communications and broadcast systems, but also radar applications. Use the FSUP26 to measure phase noise and when characterizing oscillators, measure tuning slope, transient response, power, harmonics and spurious emissions, as well as amplifier noise. The integrated DC sources enable a wide range of additional measurements.
Features and specifications of:
Frequency range up to 26.5 GHz (up to 110 GHz with external mixers)
Low Noise DC outputs for supply and tuning voltages
Maximum flexibility for phase noise measurements
Oscillator characterization
Analysis of digital and analog modulated signals
Capabilities of the FSUP26 include:
Phase detector method with internal/external reference
