Page of 5 MODEL 5854 VXIbus UNIVERSAL POWER METER UNIVERSAL POWER MEASUREMENT Introducing the 5854 Universal Power Meter. The lastest member of the Giga-tronics family of innovative VXIbus microwave test and measurement solutions. Now, for the very first time, you can get NIST traceable, lab grade CW and peak power measurements quickly and accurately from a singleslot VXIbus module. POWER MEASUREMENTS INSTANTLY The Giga-tronics 5854 is te fastest VXI power meter available. Measurement speeds exceed 5 readings per second, and our exclusive Burst Mode captures more than 5, readings in the same tick of a clock. In fact, the 5854 is so fast you can measure the power level of many swept signals, giving you the capability of a scalar analyzer without the addtional cost. Because the 5854 supports the scpi command language the standard for VXI computer controlled testing. Think about what all this will do for your ATE productivity as well as for your company s bottom line. FAST, EASY PEAK POWER MEASUREMENT The 5854 is the only VXI meter that lets you measure peak power directly. And it s as simple as attaching a peak power sensor. There are no time-consuming, unreliable duty cycle corrections.view the pulsed signal s amplitude profile on a scope and see the exact power measurement point on the pulse. THE SECRET IS THE SENSORS The Giga-tronics 5854 Universal Power Meter delivers incredible performance by taking full advantage of the speed and dynamic range of diode sensors. Giga-tronics has solved the challenge that previously limited diode sensors to the square law region below - dbm by utilizing a builtin power sweep calibration system. The power sweep calibrator uses a 5 MHz amplitude controlled oscillator to step from -3 to + dbm in db increments. Each step is set using an internal thermistor the standard for linearity. You get thermistor linearity, plus diode speed and dynamic range, for measuring signals
Giga-tronics Model 5854 VXIbus Uniersal Power Meter Page of 5 accurately over a full 9 db power range. And for incredible versatility, we offer a full range of CW and Peak sensor tailored to your spsecific needs. Our sensors cover frequency ranges from MHz to 4 GHz with up to 9 db dynamic range.there are to 5 Watt high power sensors, too. Use our diode-based True RMS sensors to accurately measure quadrature modulated signals, intermodulation distortion power and db gain compression. Use our Low VSWR sensor for unequalled CW measurement accuracy. Or connect a Precision Return Loss Bridge and measure Return Loss or VSWR using only a single channel. TWO CHANNEL OPERATION The 5854 provides two channel operation, so you can see readings from both channels simultaneously. Use one channel for CW and the other for peak measurements, and see both readings at the same time. Or read one channel in db and the other in mw for measuring gain and output power simultaneously. With all you ve got to do, imagine the ti you ll save. Accuracy Audit Assume the power meter is being used to measure the output power at GHz from a source with a VSWR=.5:.

Storing data in the power meter s memory for later down loading to your controller reduces word serial protocol and protocol conversion overhead. Up to 8, readings can be buffered. The table below illustrates typical maximum measurement rates for 83 Series Peak Power Sensors. Measurement rate depends on several factors including controller speed and number of averages. Burst Mode speed shown does not include bus communication time.
