For the very latest specifications visit www.aeroflex.com A precision Power Meter with comprehensive GPIB facilities for ATE requirements and standard bench applications Industrial counters & Power meters specifications 6960B RF Power Meter • Extensive frequency coverage: 30 kHz to 46 GHz • Wide dynamic range: -70 dBm (100 pW) to +44 dBm (25W) • Fast response on GPIB of 25 ms • Auto averaging with manual override • Both 50 Ù and 75 Ù professional sensors • Low sensor VSWR reduces measurement uncertainty • Sensor linearity correction for improved accuracy • Maximum hold facility • Optional DC operation • Non-volatile memory The 6960B RF Power Meter is a high accuracy instrument which together with its associated power sensors provides measurements at frequencies from 30 kHz up to 46 GHz over a wide range of power levels. Its numeric keyboard enables easy manual control while full GPIB implementation with SRQ mask and trigger modes make it the logical choice for fast ATE systems. Meter Accuracy The 6960B features an instrumentation accuracy of better than ±0.5% in linear mode and ±0.02 dB in logarithmic mode. A special auto zero circuit digitally stores the zero offset for each of the five ranges, thus reducing zero carry over errors to ±0.03% and providing a zero accuracy of ±1% of FSD on the most sensitive range for any sensor type. High Accuracy All power sensors are provided with detailed calibration data to 0.01% resolution. In addition to Calibration Factor data, each sensor is individually calibrated for linearity. When entered into the power meter, this data reduces linearity errors to less than ±0.5% even on the highest range. Precision Calibration Attenuators The 6920 series of high sensitivity power sensors are supplied with a precision 30 dB attenuator for calibrating to the internal power reference. These attenuators have an accuracy of ±0.05 dB at 50 MHz to provide high calibration accuracy. Duty Cycle Correction Although the 6960B is a true average power measuring instrument, it may still be used for pulsed power measurements. The duty cycle of the signal to be measured may be entered in the range 100 to 0.001%. The power meter calculates the peak power by dividing the measured average power by the duty cycle. Relative Measurements The dB REL key enables the measurement of high powers by entering the calibrated value of an attenuator or coupler directly as a negative number. Positive relative values to account for industrial amplifier gains can also be entered. The dB offset facility may be used with linear lines so that professional transmitter output powers can be displayed in Watts. Two Power-Up Modes The instrument is provided with two power-up modes. For production device testing, or applications in power monitoring at unattended sites, power-up mode 2 returns the instrument to its previous settings after switch-off or a power failure. Power-up mode 1 sets all the instrument functions to default values.
