System Connection

To set up the measurement system, follow the steps below:

  1. Connect the PC installed with N7614B Signal Studio with the RF Signal Generator and Signal Analyzer through LAN or GPIB.

  2. Connect the EVENT 1 port on the rear panel of the RF Signal Generator to the Trigger IN 1 port on the rear panel of the Signal Analyzer using a BNC cable. This is to synchronize the RF Signal Generator and Signal Analyzer in time domain.

  3. Connect the 10 MHz OUT port on the rear panel of the RF Signal Generator to the EXT REF IN port on the rear panel of the Signal Analyzer using a BNC cable.

  4. Connect the RF OUTPUT port of the RF Signal Generator to the input of the PA and connect the output of the PA to the RF INPUT port of the Signal Analyzer.
