R&S®FSUP Signal Source Analyzer
Phase noise tester and high-end spectrum analyzer in a single box
VCO Characterisation
- VCO tuning characteristic
- VCO tuning sensitivity
- VCO RF power characteristic
- VCO pushing
- Harmonic power
- VCO DC characteristic
The tuning voltage of the oscillator varies within the limits defined when the DC settings for the individual port were made. The result shows the settable frequency range and the tuning steepness of the oscillator in graphical form.
Displays the tuning steepness versus the measured frequency range or the tuning voltage. Also the output power is displayed.
Displays the output power of the signal source and the oscillator frequency as a function of the tuning voltage.
During this measurement method, the impact of the supply voltage on the frequency and power of the signal source is examined. Here the tuning characteristic of a VCO depending on the input voltage is shown.
Displays the power of up to three harmonics at different tuning voltages.
Measures how the frequency and power vary as a function of the supply voltage when the tuning voltage is held constant.
