Handheld spectrum analyser takes on the benchtops
Agilent Technologies has redesigned its handheld analyser range to improve measurement accuracy of the mil-spec microwave analyser.
In the process it has come up with a portable instrument which could potentially replace larger and more expensive benchtop spectrum analysers in the R&D lab.
FieldFox handheld analysers, with a battery life of up to three and a half hours, are designed for use by the military or microwave backhaul installations.
Now Agilent has increased the accuracy of the instruments to a level which could see them used more generally as benchtop analysers.
There is a spectrum analyser and a vector network analyser available in four frequencies, which are 9, 14, 18 or 26.5GHz.
There is also a combined analyser.
The microwave vector network analyser can provide full two-port S-parameter measurements with a low trace noise of ± 0.004 dB and dynamic range of 94dB (up to 18GHz over -10 to 55 °C/14 to 131 °F).
The handheld spectrum analyser has amplitude accuracy of ±0.5dB. Phase noise is specified at of -111dBc/Hz at 10kHz offset and spur-free dynamic range is 105dB.
The capabilities of the instruments look even more attractive as benchtop analysers with a built-in power meter, independent signal generator and a frequency counter with timing accuracy provided by a built-in GPS receiver.
Another feature of the VNA is a measurement calibration function which does not require the use of external accessories.
