EPM Series Power Meters Firmware Archive

The EPM Series power meters (E4418B single channel and E4419B dual channel) provide a low-cost, high-performance, programmable power meter for CW and average power measurements. They are compatible with the 8480 series and E Series power sensors (except the E9320A family). Depending upon which sensor is used, the EPM Series power meters can measure average power over -70 dBm to +44 dBm, at frequencies from 9 kHz to 110 GHz.
