December, 2014 Bird Technologies: Statistical RF Power Sensor
Solon, OH — Bird Technologies has introduced the Model 7022 Statistical RF Power Sensor, the only thruline RF power measurement device that pro- vides the statistical analysis capability required to accurately characterize the RF power characteris- tics of any digitally-modulated signal used in wire- less communications systems. The power sensor measures power levels from 250mW to 500W over a frequency range of 350MHz to 6GHz and is an excellent choice for applications ranging from per- formance optimization to maintenance and trou- bleshooting. It is extremely compact, lightweight, and rugged, measuring only 5.8 x 4.8 x 1.3-in. (147 x 122 x 33mm) and weighing 1.5-lb. (0.68kg), mak- ing it well suited for use in the field. In addition to measuring the statistical prop-
erties of digital waveforms, it provides a complete range of other RF measurements including for- ward and reflected average power, VSWR, and return loss.
The Model 7022 includes the latest version of
Bird’s VPM3 Windows-based Virtual Power Meter software that when installed on a Windows-based laptop, tablet, or desktop computer to provide a comprehensive user interface for configuring measurements, viewing results, and exporting
data for trend analysis in spreadsheets. The non-periodic time-domain characteristics
of digitally-modulated signals make it impossible to accurately characterize them using convention- al RF power measurement techniques. Benchtop instruments with statistical measurement capabil- ity have been available for some time, but the Bird Model 7022 is the first to incorporate them in a thruline USB-connected power sensor suitable for use in any environment from periodic field meas- urements to installation in base stations. The instrument has three operating modes.
Statistical power sensor.
In “conventional” mode it functions much like a traditional RF power sensor, measuring forward and reflected average power, VSWR, and return loss. In “time-domain” mode it displays time- domain waveform characteristics and provides markers to determine average burst power, peak power, and other pulse-related parameters. In “statistical” mode it measures peak-to-average power ratio versus the time in per- cent that the waveform is at or exceeds a specific peak/average
power ratio. Contact: Bird Technologies

–117dBc/Hz at 10kHz offset and has excellent linearity. Output power is typically +2.5dBm. Engineered and manufactured
in the USA, the new VCO is pack- aged in the industry-standard 0.5 x 0.5-in. (12.7 x 12.7mm) SMD pack- age. Input voltage is 5V, with a max. current consumption of 20mA. Pulling and Pushing are minimized to 2MHz and 1MHz/V, respectively. Second harmonic suppression is –8dBc typical. The CVCO55CC-1680-1680 is
suitable for use in applications such as digital radio equipment, fixed wireless access, satellite communica-
tions systems, and base stations. Contact: Crystek Corporation,
