Power Sensor Measurements vs. Frequency (continued)
Description
Measurements
Source power, gain/loss and receiver (Rx) power
Gain = Rx power / source power (memory). Source power (memory) is measured during
setup.
Output power
Dynamic range
Refer to the test port output power typical data on page xx
The dynamic range with FOPS is dependent on FieldFox’s output power and the power
sensor’s dynamic range. Supported USB power sensors:

The graph below shows a filter measurement using two different power sensors, the U2002A (-60 to +20 dBm) and the
U2021XA (-45 to +20 dBm).
While a filter is not commonly measured using FOPS, it is a useful device for demonstrating dynamic range.
For both measurements, the FieldFox source power was set to 0 dBm, the maximum available in the selected frequency
range of 150 to 450 MHz.
