Analog Measurements - Screens and Control Fields

Control Fields for Analog Measurements

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.

Position

This field indicates the number of scale divisions from the left side of the screen to the marker.

Use the DATA ENTRY keys or cursor-control knob to move the marker to any point on the displayed signal.
