An alternating electrical current or a magnetic, electric, or electromagnetic field or mechanical system's oscillation rate that lies around 20 kHz to around 300 GHz is known as radiofrequency. Frequencies immediately below RF are audio frequency (AF) ranging from 20 Hz to 20 kHz Radio frequency covers all the way upto the range of extremely high frequency.

This definition refers to the electromagnetic waves themselves, which carry the radio data signals being part of today's most important technologies. Radio frequencies are also called "radiotelephone frequencies" when used as a radio telephony system.

What frequency range does a Fieldfox have?

FieldFox Handheld Analyzers operate from 3 kHz to 300 GHz. This range is wide enough to allow complete testing of most power grids and high voltage equipment. It is also used to analyze microwave components such as filters, couplers and other devices.

Oscilloscopes are used to measure voltage waves, while FieldFox Handheld Analyzers can perform most electrical measurements and can enhance the capabilities of analyzers. Oscilloscopes operate with frequencies up to the hundreds of MHz range and with bandwidths of around 100 MHz or higher. There are many applications where the oscilloscope's frequency range will not be wide enough to provide a quality measurement. A major reason is the oscilloscope’s limitation as it lacks the capability of examining high frequency sharp rise time transients.FieldFox Handheld Analyzers have a much wider frequency range, going from 3 kHz to 300 GHz, with a typical limit of 10 MHz.

Although FieldFox Handheld Analyzers are not oscilloscopes, they allow you to create waveforms that resemble voltage or current signals within known component specifications. For example, the spectrum analyzer function produces a graph that resembles an oscilloscope display.

FieldFox Handheld Analyzers are capable of analyzing power grids where oscilloscopes cannot reach. Since the FieldFox runs on battery or USB power, it can go to the job site, where other instruments cannot.

Signal generators produce electrical signals at the desired frequency over a range of voltages. The FieldFox can test equipment, subsystems, or complete systems. What sets them apart from traditional signal generators is that they can test both RF signals and power grids simultaneously.

The FieldFox Handheld Analyzer is different from a signal generator because it can generate a signal and measure many parameters with one hand-held device. It does not need a separate power supply or calibration, the only thing needed is the unit itself as it is portable and battery-powered. This makes it more efficient for field test engineers to use.

Spectrum analyzers display the amplitude and frequency of a signal within a specific bandwidth according to the frequency range of the given instrument. A spectrum analyzer measures power over a range of frequencies instead of a specific frequency.

FieldFox Handheld Analyzers are different from spectrum analyzers because they can simultaneously test RF signals and power grids. FieldFox can do all the measurement functions that a spectrum analyzer and oscilloscope can do without needing separate instruments for each function, making it more efficient to use in many situations.

Yes, the unit is equipped with an integrated USB port that enables the user to download recorded waveforms and data to a PC running FieldFox software. But, you will need a standard USB cable for this purpose.

Yes, LAN connections are compatible with the FieldFox handheld analyzer which allows you to send your data to a computer. The setup is simple and can be done through the LAN wizard in the Windows control panel. But, you need to make sure that the LAN connection is 100Base-T speed or faster in case you choose the firmware A.03.06 or earlier.

The FieldFox is equipped with CalReady and QuickCal built-in software that makes calibrating in the field simple and efficient. FieldFox also provides a selection of mechanical calibration types when a calibration kit is available. Regardless of how you are calibrating, the FieldFox will walk you through performing a user calibration using the built-in "Calibration Wizard," which guides you step by step.

Note: This way of calibrating is available in all Fieldfox “A” models.
