Fields

Port/Sweep

This control performs two functions:

The upper field specifies the output port of the Tracking Generator.

The lower field specifies whether the Tracking Generator sweeps from low-to-high fre- quencies (Norm), or from high-to-low frequencies (Invert). (The Spectrum Analyzer always sweeps from low to high frequencies.) The swept frequency range is determined by the Span setting in the Spectrum Analyzer’s Main Menu.

Operating Considerations

When using the Tracking Generator, if the output port is set RF Out, or the main menu Input Port is set to RF In, internal instrument coupling can occur. For the best isolation between the Tracking Generator and the Spectrum Analyzer, use Dupl for the output, and Ant for the input.

For measurements on high-power devices, such as amplifiers, use the RF IN/OUT port for the input.
