Additional Features:

• Frequency range: 18 GHz
• Calibrated in watts and dBm
• Accuracy is ±1% of full scale on all ranges
• Accuracy is ensured by the following: an internal automatic zeroing circuit which removes error due to the ambient temperature output of the power sensing device, a calibration factor adjustment which accounts for error due to the frequency response of the power sensing device, and a internal calibration reference which has an output of 1 mW (±0.7%).

The system power level range, frequency response, and load impedance are dependent on the power system. The Agilent 435A meter has a frequency range (dependent on power sensor) of 100 kHz to 18 GHz.
