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 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.
Cost
Depends on sensor, but more than Option 310
External hardware
U2000x power sensor required.
None required. Built-in capability.
Power detection
Broadband diode detector
Tuned receiver
Frequency range
Depends on USB sensor
Supported sensors
Sensors available in 6, 18, and 24 GHz models.
100 kHz to 14 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).
