Use Case: COMMS System, multiple test points

When you want to compare the performance of your device at different locations within the RF Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz). path, you can use external triggering to synchronize multiple instruments (Time-Synchronous Acquisition).

To configure this setup, connect the appropriate hardware to each section of the RF path you wish to measure and then connect the external Trigger OUT of one instrument to the Trigger IN of the others. Then configure the VSA as described in Making a Triggered Multi-Measurement.

Benefits

Calculate RF component's transfer functions - user-defined VSA math functions can be used to calculate the transfer functions between different measurement points. For example, baseband -> IF transfer function.
