test
Return loss/VSWR measurements allow you to evaluate the
impedance matching performance of the feed line across the
frequency range of interest.
Distance-to-fault measurements help you identify the faults
along a feed line. Use these measurements to precisely pinpoint
the location of damaged or degraded antennas, connectors,
amplifiers, filters, and duplexers, etc.
FieldFox provides up to 1001 data-point resolution to help accu-
rately locate faults and extend measurement distance.
Transmission test
Transmission test is used to accurately measure cable loss,
insertion loss (filters), and amplifier gain (tower mounted ampli-
fier). FieldFox offers two-port transmission magnitude measure-
ments with up to 72 dB dynamic range.
For already-installed cables, FieldFox accurately measures cable
loss via the RF Out port. The instrument measures actual cable
loss, without the need for additional computation.
CalReady at test port Each instrument is calibrated at the RF Out port. When you
power up the instrument, it is ready to make measurements such
as one-port cable loss, VSWR, return loss, and DTF at the test
port.
QuickCal The industry’s-first and only built-in calibration system allows you
to calibrate the cable and antenna tester without carrying a calibra-
tion kit with you all the time. It provides worry-free accuracy and
excellent repeatability.
Mechanical
calibration
Open-short-load (OSL) is standard in FieldFox. There are four
calibration kits defined in the instrument.
Spectrum analysis The built-in spectrum analyzer allows you to scan up to 6 GHz and
detect internal and external interference. FieldFox can detect sig-
nals as low as -148 dBm up to 6 GHz, with phase noise of -88 dBc
at 10 kHz, and a third order intercept (TOI) better than +18 dBm.
Limit lines Use limit lines or masks for pass/fail testing. You can set up
both fixed and relative limit lines, or build a limit line table from a
current trace.
Interference analyzer Spectrogram and waterfall displays allow you to detect and
monitor intermittent interference signals. The interested signals
can be recorded and played back.
Field strength
measurements
Antenna factors and cable loss data can be loaded using either
the front panel or the Data Link software. Field strength can be
displayed in dBuV/m, dBuA/m, dBG or dBpT.
Enables operators to find exact locations and time/location
stamp their measurement reports. The GPS information can be
displayed on the screen and saved as part of the image, data or
recorded signal.
