Gigatronics 8650A Overview

The Giga-tronics 8650A Series Universal Power Meters have the extensive measurement capabilities and features you need to test today's sophisticated communications systems faster, easier and more accurately.

The 8650A can measure the CW power, peak power and average power of TDMA, GSM, and CDMA (both IS-95 and third-generation 10 MHz wide band) signals. CW measurement speeds (readings/second) over GPIB are >1,750 and modulated measurement speeds are >300. And the meter includes many time saving features such as automatic time gate setting, direct crest factor measurement, and statistical power measurement analysis.

SENSORS
The Fastest CW Measurements Giga-tronics 80300A Series CW Power Sensors let you measure CW power from 10 MHz to 40GHz 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 Power Sensor to an 8650A meter and directly measure the instantaneous peak power level of a pulse modulated signal. Use the "sample delay" function to set the desired measurement point on the waveform. And an external scope can be used to view the profile and see the exact measurement point on the pulse.

Modulated Power Measurements The Giga-tronics 80400A Series Modulated Power Sensors let you measure the average power of amplitude modulated, burst modulated and other complex modulated signals -- such as TDMA signals -- at bandwidths up to 40kHz.

The Giga-tronics 80600A Series Modulated Power Sensors provide bandwidth up to 1.5 MHz to measure the peak and average power of CDMA signals. And the Giga-tronics 80701A Modulated Power Sensor operating with the 8650A power meter, provides system bandwidth up to 10 MHz to measure peak and average power of wide band, third-genration CDMA signals over an 80 dB range.
