E4419B Dual-Channel Power Meter

The Keysight E4419B is a low-cost, high-performance, dual-channel, programmable power meter. The E4419B is fully compatible with the 8480 series and the E-series power sensors (except the E9320A family). Depending upon which sensor is used, the E4419B power meter can measure from -70 dBm to 44 dBm at frequencies from 9 kHz to 110 GHz. Designed for bench and automatic test equipment (ATE) use, the E4419B makes fast (up to 200 readings per second with E-series sensors), accurate and repeatable power measurements.
Here are the key features of the Keysight E4419B:
True dual-channel power meter – two simultaneous power readings
Fast measurement speed (up to 100 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 switching point with E-series sensors
Code compatibility with 438A power meter
GPIB and RS232 connector for remote control of all functions
Internal rechargeable battery option provides up to 4 hours continuous use (option 001)
