8650B Series Universal Power Meters The Giga-tronics 8650B Series Universal Power Meters have the extensive measurement capabilities and unique features required to test today’s sophisticated communications systems faster and more accurately. TDMA The 8650B can automatically measure the average power of pulse modulated signals or pulse signals that are amplitude modulated during the pulse ‘on’ period - such as TDMA signals. Using the exclusive Burst Average Power mode (BAP), the average power reading in the pulse burst is automatically measured between the 3 dB points. Therefore, the duty...

8650B Series Universal Power Meter The Features to do the Job - Faster, Easier and More Accurately CREST FACTOR The crest factor capability of the 8650B displays the ratio of the maximum peak power (peak hold) measurement to the average power measurement (in dB) from the time the feature is enabled until it is reset. The crest factor capability operates in the same manner as the peak hold capability: the display value holds at the maximum until it is reset. INCREDIBLE SPEED AND STATISTICAL ANALYSIS No other meter delivers the measurement speed available from the 8650B. Achieve over 1,750...

8650B Series Universal Power Meter Accuracy and Built-In Calibration ACCURACY OVER A 90 dB Range Giga-tronics has solved the problem that limited the use of diode sensors to below -20 dBm – the ‘square law’ region – by utilizing a patented built-in power sweep calibration system. The power sweep calibrator uses a 50 MHz amplitude controlled oscillator to step from -30 to +20 dBm in 1 dB increments. Each step is set using an internal thermistor – the standard for accuracy and traceability. Giga-tronics gives you thermistor accuracy plus diode speed for measuring signals over a full 90 dB...

8650B Series Universal Power Meter The Secret is the Sensors 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 and 81300A Series CW Power Sensors let you measure CW power from 10 MHz to 50 GHz at more than 1,750 readings per second over GPIB. Measure up to 90 dB2 with a single sensor, and select from a variety of high power sensors,...

8650B Series Universal Power Meter by 2.15" high Liquid Crystal Display 0.38 mm pitch, and Cold Cathode Fluorescent Lamp (CCFL) back light for maximum detail and optimum Each sensor uses an EEPROM to store values ofcal factor. Entering the measurement frequency automatically calls up the correct cal factor. If the measurement frequency is between cal factor points, the meter automatically enters an interpolated value. Sensor Freq Compensatior 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...

8650B Series Universal Power Meter 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 specified Cumulative Distribution Function (CCDF) reorients the CDF curve in accordance with the equation CCDF = 1-CDF for more accustomed viewing of a descending slope. Moving a cursor along the slope of the curve displays the power level in dBm and the corresponding percentage of...
