Keysight / Agilent 478A - RF Power Measurement

Keysight / Agilent 478A Overview

The Agilent 478A provides high efficiency and good radio frequency (RF) match. Used in conjunction with the N432A or 432A power meters, they provide high accuracy even in routine power measurements. These thermistor mounts are temperature compensated for low drift, even in the presence of thermal shocks, permitting measurement of microwave power as low as one microwatt. Each mount contains data showing calibration factor and effective efficiency at six frequencies, directly traceable to the U.S. National Institute Standards and Technology (NIST) at those frequencies where NIST provides calibration service.

Features:

High accuracy even in routine power measurements
Temperature compensated for low drift
Measures microwave power as low as one microwatt
Shows calibration factor and effective efficiency at 12 frequencies
Frequency Range: 10 MHz to 10 GHz
Maximum SWR: 10 MHz to 25 MHz 1.75; 25 MHz to 7GHz 1.30; 7 GHz to 10 GHz 1.50
Available options: 478A-H75 and 478A-H76 for frequency range 1 MHz to 1 GHz (Max. SWR 1.3, 1.05 at 50 MHz). 478A-H76 provides standard lab calibration at 50 MHz
