Fast measurement speed (up to 200 readings per second, over the GPIB, with E-series sensors)

Speed improvement of x2 using the 8480 series power sensor (compared to the 437B)

No range-switching delays with 8480 series sensors, and only one fast-range switch point with E-series sensors

Code compatibility with 437B and 436A power meters

GPIB and RS232 connector for remote control of all functions
