Analog Measurements - Screens and Control Fields

Port/Sweep Port/Sweep

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 frequencies (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 controls menu.

This field is displayed only when Track

is selected in the Track/Fixed

field on the spectrum analyzer’s RF Gen controls menu.

Operating Considerations

When using the tracking generator, if the output port is set to 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.
