The devices are expected to be used in the design, installation and maintenance of radio frequency systems including analogue and digital cellular, 3G, 4G, GSM, GPRS, EDGE, UMTS, HSDPA, Tetra, APCO/P25, WiMAX and WLAN, CDMA, TDMA and WCDMA, as well as in specialised systems used in the transportation, tactical military, radar, avionics, marine, LMR, broadcast, paging, public safety, telematics and utilities sectors.
The WPS range is exclusively being stocked by Aspen Electronics covering both the UK and Europe. The five new models cover a frequency range from 25MHz to 4GHz and a power measurement range from 25mW to 500W Average Power. Models include the 5012A with a frequency range of 350MHz to 4GHz and a power range of 150mW to 150W average, 400W peak and the 5018 with a frequency range of 150MHz to 4GHz and a power range of 25mW to 25W average, 60W peak.
Based on Bird’s Thruline design concept, all the major components required for power measurement are included in one module. The power sensors contain all the elements of a traditional RF power measurement system: a high power, low loss, high directivity coupler; two high accuracy detectors (one each for forward and reflected power measurements) plus digital processing circuitry for connection to a PC for capturing and storing readings, via a USB interface.
Measurements performed include true average power, peak power and duty cycle. Calculations performed include VSWR, return loss, reflection coefficient, crest factor, average burst power and CCDF. In addition, Bird’s free to download VPM2 software package brings virtual power meter and data logger functions to the PC, adding a host of extra features.
The WPS can be interfaced directly to the Bird 5000-XT handheld Digital Power Meter, and is compatible with the Bird SA range of Site Analysers and the Bird Signal Hawk range of handheld spectrum analysers.
With a quoted accuracy of ±5% of reading, the WPS does not need field calibration, and only requires calibration at a laboratory just once per year. By incorporating virtual instruments into the same unit, the WPS generates further saving on total annual calibration costs. For more information Aspen can provide the WPS Calibration technical note.
The Bird wideband power sensors are manufactured in the US and are RoHS compliant.
