Tuning
Document Part No. E5500-90024Ed. 1.0
The tuning range of the voltage-controlled-oscillator (VCO) source
must be commensurate with the frequency stability of the sources
being used. If the tuning range is too narrow, the system will not
properly phase lock, resulting in an aborted measurement. If the
tuning range of the VCO source is too large, noise on the control line
may increase the effective noise of the VCO source.
