This section provides a brief overview of the available options covered in this guide.
Note
Not all instrument models offer every option. Some options are available as a time-limited trial. For example, High Accuracy Power Meter is offered as a 90-day time-limited option by ordering Option 9019. The option start time begins when the user first activates the option. Please refer to the Technical Data Sheet of your instrument for information on purchasing and activating time-limited options.
The High Accuracy Power Meter Option 19 uses an external USB power sensor (sold separately) to facilitate high accuracy power measurements using Field Master Series instruments as the host controller. Refer to Table: Option 19 USB Power Sensors in High Accuracy Power Meter (Option 19).
