Key Features & Specifications

  • 100 kHz to 18 GHz
  • ± 0.5 dB accuracy for CW signals
  • No warm-up required
  • Watts, dBm, absolute and relative measurements
  • Large analog display


Option 310 provides the functionality to make user-definable channel power measurements such as transmitter output power. By leveraging InstAlign technology, FieldFox is able to make very accurate channel power measurements. The table below lists the differences between the built-in power meter Option 310 and the USB power sensor Option 302.

  Option 302
USB power sensor
Option 310
Built-in power meter (or channel power meter)
Description Option 302 allows users to connect a USB power sensor to FieldFox’s USB port and read the power level on FieldFox’s display. Option 310 is a channelized power measurement capability built into FieldFox analyzers.
External hardware U2000x power sensor required. None required. Built-in capability.
Power detection Broadband Tuned receiver
Frequency range Depends on USB sensor
Supported sensors
100 kHz to 18 GHz
Usable from 5 kHz
Settings Set CW frequency Set CW frequency
Set channel width/span (max: 100 MHz)
Radio standard selection for frequency and channel control
Power range

Depends on USB sensor
Supported sensors
A models: -60 to +20 dBm
B models: -30 to +4 dBm
H models: -50 to +30 dBm

Depends on channel width and attenuator setting. Approximately from -120 to +20 dBm.
Warm-up time 30 minutes to meet accuracy specifications No warm-up time required.
Accuracy Depends on USB sensor
Supported sensors

InstAlign accuracy: ± 0.5 dB typical for a CW signal

Note: Since the measurement is channelized, to make an accurate measurement, the user needs to know the center frequency and the signal’s characteristics.

Display Large analog display, watts and dBm, relative and absolute measurements Large analog display, watts and dBm, relative and absolute measurements
Programmable via SPCI Yes Yes
Physical connection The sensor can easily be moved to the measurement point, with a USB cable connecting the detector to FieldFox. The measurement point needs to be connected to FieldFox’s RF input port. If a RF jumper cable is used, the user needs to account for the loss of the cable with an offset value (can be entered into the analyzer).
Internal FieldFox source control Yes
Can set source on/off

This option can be added as a product upgrade.
