Agilent EPM-441A Power Meter w /Opt. 002

The Agilent EPM-441A is a single-channel power meter engineered for precise RF and microwave power measurements from 100 kHz to 110 GHz, depending on sensor selection. With Option 002, the instrument features parallel rear-panel sensor inputs and a front-panel power reference oscillator, enabling flexible sensor configurations across R&D, manufacturing, and service environments.

– Technical Specifications

Frequency Coverage — 100 kHz to 50 GHz (sensor dependent) or 75 GHz to 110 GHz (sensor dependent).

Power Range — −70 dBm to +44 dBm (100 pW to 25 W), sensor dependent.

Dynamic Range — Up to 90 dB maximum with HP ECP series sensors; up to 50 dB maximum with HP 8480 series sensors.

Measurement Rate — Up to 200 readings per second with ECP series sensors or up to 100 readings per second with 442A.

Absolute Accuracy — ±0.02 dB (logarithmic) or ±0.5% (linear mode). Relative accuracy: ±0.04 dB (logarithmic) or ±1.0% (linear). Sensor linearity percentage must be added to instrumentation accuracy.

Power Reference Oscillator — 1.00 mW (0.0 dBm) output with ±0.7% factory-set accuracy traceable to NIST; ±1.2% worst-case accuracy (±0.9% RSS) for one year.

Display — High-resolution LCD with LED backlighting and contrast control. Selectable units: Absolute (Watts or dBm) or Relative (Percent or dB). Resolution options: 1.0, 0.1, 0.01, and 0.001 dB in log mode, or 1 to 4 digits in linear mode. Default: 0.01 dB (log) or 3 digits (linear).

– Key Features
