RF Explorer Tracking SNA mode

This feature enables fast and accurate diagnostics of cables, filters, and amplifiers. When used with a directional coupler, it extends functionality to measure impedance and characterize antenna VSWR, providing comprehensive RF performance analysis.

Some parameters can be easily configured by screen touch with yellow areas in picture above.

Press each of these regions to change:

• Measure Data - Change with selection dialog
• Generator Power - Change with dialog
• Sweep Average - Change with numeric dialog
• Sweep Speed and Points - Change tracking sweep steps with numeric dialog

Power

Steps

Tracking SNA steps. The more steps you use, the longer the sweep will take. Recommended values are from 50 to 200 steps for a good compromise of speed and resolution.

A standard SNA requirement ensures the elimination of any imperfections caused by cables, connectors, or environmental factors. The application accurately measures your setup's response and sets it as the 0 dB reference, allowing all subsequent measurements to be normalized accordingly.

Perform/Finalize SNA for continuous tracking sweep. Screen will be updated with SNA results every few seconds.

The Start button is available when normalization process done successfully.

The Stop button is available while performing tracking process.
