Depending upon which sensor is used, the e441819b can measure from -70 dbm to +44 dbm at frequencies from 9 khz to 110 ghz.
the e4418b power meter is designed for bench and automatic test equipment (ate) use.
* 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
* internal rechargeable battery option provides up to 5.5 hours continuous use (option 001).
