FieldFox microwave analyzers deliver precise measurements in virtually any field environment: Page 3 of 4

October 29, 2012 // By Agilent Technologies
For most, the phrase “precise microwave measurements” brings to mind a lab bench in a comfortable office. These days, more and more technicians and engineers need to make accurate measurements in less hospitable conditions: in a BTS during a snowstorm, aboard a ship sailing through rough seas, or at a satellite trailer in a sandstorm.
to enable operation in darkness.

Applying Agilent’s measurement science

The electronic design of FieldFox is a classic example of what Agilent can do. Before FieldFox, our technology portfolio included a host of high-performance chips that deliver best-in-class measurement performance. For FieldFox, our best measurement scientists extended those technologies to provide high performance with low power consumption. The result: FieldFox consumes about 15 W and lasts 3.5 hours on a single charge. And because it consumes just 15 W of power, the enclosure can be completely sealed.

Filling the gaps

There are other handheld analyzers on the market. Beyond our own technological assessments, we also asked end users about their opinions and experiences. They identified four key issues with handhelds they had tried or were using:

  1. Most are not designed to operate in real-world moisture, rain, humidity, dust or temperature changes.
  2. Most have a too-short battery life.
  3. Field measurements seldom agree with lab or production-line results.
  4. It’s difficult if not impossible to make accurate signal-power measurements when the ambient temperature is fluctuating.

FieldFox fills all these gaps.

Leveraging our microwave heritage

A FieldFox analyzer contains capabilities borrowed from Agilent’s benchtop analyzers — many of which are today’s best microwave instruments. By providing levels of precision not available in any other handheld instruments, FieldFox ensures greater confidence in results.

In network analysis, built-in calibration engines leverage extremely accurate algorithms from high-end VNAs — and this enables precise and repeatable measurements in the field. Our approach to calibration hardware is borrowed from benchtop VNAs. With an emphasis on portability, Agilent simplified calibration by adding built-in calibration standards, so measurements can be made in the field without carrying additional accessories. With any other instrument, when additional devices to the test port are added, such as jumper cables, recalibration is required using an external calibration kit. CalReady is another unique feature that saves time in the field — turn it on and it’s already calibrated.
