R&S®FSUP Signal Source Analyzer
Phase noise tester, high-end spectrum and signal analyzer in a single box
Test Setup
Easy setting of test setup in configuration menu with display of recommended measurement range.
Helpful schematics
Measurement carried out on two identical oscillators. The final result is corrected by 3 dB.
Phase Noise Measurement
Listing of all important parameters for a stable phase noise measurement using the phase detector method.
Typical phase noise measurement with the phase detector method: Signal frequency, level and residual FM/φM are displayed.
Spot Noise vs. Tuning Voltage
Phase noise values of an oscillator at different offset frequencies as a function of tuning voltage.
Residual Phase Noise
Typical test setup for residual noise measurements.
Through a 90° phase shift of the paths, inherent generator noise is eliminated, leaving only the noise caused by the DUT.
Cross-correlation
Cross-correlation: Two identical receiver paths minimize the influence of the internal reference. The additional microwave frequency converter enables measurements up to 50 GHz.
Improvement of phase noise sensitivity by means of cross-correlation. Measurement of the phase noise of a signal source at 25.8 GHz without cross-correlation (green trace) and with cross-correlation, 100 (violet) and 1000 (yellow) averages.
Spectrum Analyzer method
A phase noise measurement using the spectrum analyzer. The blue trace shows the measurement result up to an offset frequency of 1 GHz. The inherent noise (green trace) is subtracted from the measured signal (yellow trace).
ACP
Measurement of the adjacent channel power of a 3GPP base station signal.
Analysis in the time domain
Transient response of a generator.
DC Sources
Menu for setting the DC ports for signal source analysis and additional port for negative supply voltage.
VCO tuning characteristic
VCO tuning characteristic: The result shows the settable frequency range and the tuning slope of the oscillator.
Vector Signal Analysis
Constellation diagram of an EDGE signal, analyzed with the
Mobile Communication GSM
Measuring the modulation spectrum of an EDGE burst.
Mobile Communication 3GPP
WCDMA code domain power measurement by means of the
Analog Demodulation
Demodulation of an AM-modulated signal: Power, modulation depth and frequency are displayed. An AF spectrum can also be calculated, which displays the SINAD and THD results.
