The HP E4419A is a low-cost, high-performance, dual-channel, programmable power meter. It is fully compatible with the HP 8480 series of power sensors and the new ECP series of power sensors. Depending upon which sensor is used, the HP E4419A can measure from –70 dBm to +44 dBm at frequencies from 100 kHz to 110 GHz. Designed for bench and automatic test equipment use (ATE), the E4419A makes fast (up to 100 readings per second with ECP series sensors), accurate and repeatable power measurements. The HP E4419A is a true dual-channel power meter, which means that you get two simultaneous power readings on the display. The E4419A power meter has a high-resolution LCD display with LED backlighting and contrast control. This allows users to see the power readings from a distance, at a wide viewing angle and in a variety of lighting conditions. Users can display both the digital and analog types of readout on the meter’s split screen facility. Specifications. Frequency Range: 100 kHz to 50 GHz and 75 GHz to 110 GHz, sensor dependent. Power Range: –70 dBm to +44 dBm (100 pW to 25 W), sensor dependent. Power Sensors: Compatible with all HP 8480 series and HP ECP series sensors. Single Sensor Dynamic Range: 90 dB maximum (HP ECP series sensors), 50 dB maximum (HP 8480 series sensors). Display Resolution: Selectable resolution of 1.0, 0.1, 0.01, and 0.001 dB in log mode, or 1 to 4 digits in linear mode. Accuracy Instrumentation Absolute: ± 0.02 dB (log) or ± 0.5% (linear). Add the corresponding power sensor linearity percentage. Options. Opt 002, Supplies rear-panel sensor input (power reference calibrator is on front panel). Opt 003, Supplies rear-panel sensor input (power reference calibrator is on rear panel). Opt 004, Deletes the HP 11730A sensor cable.
