UNIVERSAL POWER METERS

The Capabilities to Test Today’s Sophisticated Communications Systems The Giga-tronics 8650A Series Universal Power Meters have the extensive measurement capabilities and unique features required to tude modulated during the test today’s sophisticated pulse ‘on’ period — such as communications systems TDMA signals. faster and more accurately. Using the exclusive Burst Average Power mode (BAP), TDMA the average power reading in The 8650A can automatically the pulse burst is automatimeasure the average power cally measured between the of pulse modulated signals or 3 dB points. Therefore, the...

Giga-tronics 8650A Features and Specications CDMA The 8650A has the wide, 80 dB single sensor dynamic range required for CDMA signal open-loop tests, the speed you need to quickly measure power during closed-loop tests, and the 10 MHz bandwidth needed to test third-generation CDMA signals. AVERAGE POWER INSTANTANEOUS PEAK POWER You can also measure the instantaneous peak power level of a pulse modulated signal with the 8650A. SELECTED SAMPLE POINT 8650A lets you display the A built-in delay line lets you highest instantaneous power trigger a few nanoseconds measured from the time the ahead...

Accuracy Audit Unrivaled Accuracy and Built-In Calibration The Accuracy Audit table lists the signicant uncertainties of an absolute power measurement. The accuracy of the 8650A combined with the 80301A sensor is compared to a typical thermocouple sensor/meter combination at +20 dBm, 0 dBm, and –30 dBm (the dynamic limit of the thermocouple sensor). The uncertainty comparison at –30 dBm illustrates the accuracy advantage of a wide dynamic sensor, even when the full 90 dB dynamic range is not utilized. +20 dBm Frequency = 1 GHz; Source Giga-tronics uses diode sensors exclusively to provide...

Giga-tronics power meter architecture provides for a broad choice of functional sensors. Just by changing a sensor,you can measure CW power,pulse power,and the peak and average power of TDMA,GSM and CDMA signals faster,more accurately,and over a wider range. THE FASTEST CW MEASUREMENTS Giga-tronics 80300A Series CW Power Sensors let you measure CW power from 10 MHz to 40 GHz at more than 1,750 readings per second over GPIB. Measure up to 90 dB with a single sensor, and select from a variety of high power sensors, up to 50 W. PULSE POWER MEASUREMENTS Attach a Giga-tronics 80350A Series Peak...

SEE FOR YOURSELF The 8650A incorporates a 3.72” wide by 2.15” high Liquid Crystal Display (LCD) with 240 x 120 dot resolution, 0.38 mm dot pitch, and Cold Cathode Fluorescent Lamp (CCFL) back light for maximum detail and optimum viewing. The large display lets you see more information. And the display works in tandem with the meter controls to let you view menu selections and see your input data as you enter it. You can view calibration information, select a standard mode, setup and recall precongured, custom modes, and set measurement points and durations. Each sensor uses an EEPROM to...

View the mean power and standard deviation of the modulated signal over a time period of interest. Standard deviation offers an alternative descriptive analysis of the power variation when compared to the traditional crest factor. The Cumulative Distribution Function (CDF) shows the percentage of time a signal is below a selected power level. The x axis displays the amount of power at the selected level, measured in dBm, and the y axis displays the percentage of time the power is at or below the power specied by the x axis. The Complementary Cumulative Distribution Function (CCDF) reorients...
