The HP Agilent EPM-442A (same as PN: E4419B) is a low-cost, high-performance, dual-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 EPM-442A can measure from -70 dBm to +44 dBm at frequencies from 9 kHz to 110 GHz. Designed for bench and automatic test equipment use (ATE), the EPM-442A makes fast (up to 100 readings per second with E-series sensors), accurate and repeatable power measurements.
The EPM-442A is a true dual-channel power meter, which means that you get two simultaneous power readings on the display.
