Option 310 is the built-in power meter option for the Field Fox analyzer.

Using the built-in power meter, FieldFox is able to make very accurate channel power measurements. The channel bandwidth can be set wide to simulate average power meter measurements. This measurement function provides the flexibility to make user-definable channel power measurements.

• Make accurate, user-definable channel power measurements such as transmitter output power with no additional external hardware.
• View measurements easily by emulating the power meter user interface with analog and digital displays
