Keysight E4418A EPM Power Meter
The Keysight E4418A is a low-cost, high-performance, single-channel, programmable power meter. It is fully compatible with the 8480 series and the E-series power sensors (except the E9320A family). Depending upon which sensor is used, the E4418A can measure from -70 dBm to +44 dBm at frequencies from 100 kHz to 110 GHz.
Designed for bench and automatic test equipment (ATE) use, the E4418A makes fast (up to 200 readings per second with E-series sensors), accurate and repeatable power measurements.
