Option 302
USB power sensor
Option 302 allows users to connect a
USB power sensor to FieldFox's USB
port and make broadband power
measurements.
USB power sensor required
Broadband diode detector, measures
all frequencies
Depends on USB sensor
Set CW frequency
Depends on USB sensor
30 minutes to meet accuracy
specifications
Depends on USB sensor
Yes, via SCPI
The power sensor can easily be
moved to the measurement point,
with a USB cable connecting the
detector to FieldFox.
Yes, on/off, and nominal power level
control
Option 310
Built-in power meter (or channel power meter)
Option 310 is a channelized power measurement capability built
into FieldFox analyzers. Maximum bandwidth is 100 MHz.
None. Uses internal receiver.
Tuned receiver, so measures frequencies within defined channel
bandwidth
Frequency range of the analyzer
Set CW frequency, Set channel width/span
Depends on channel width and attenuator setting.
No warm-up time required
InstAlign accuracy: ± 0.5 dB typical for a CW signal. Since the
measurement is within a certain frequency channel or bandwidth,
to make an accurate measurement, the user needs to know the
exact center frequency and the signal's bandwidth and set those
accurately.
Yes, via SCPI
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).
No access to FieldFox's source from the built-in power meter mode
