Absolute Terahertz Power/Energy Meter

A new USB version of our successful absolute power meter support unit is now available,

with continuous FFT display of noise and dynamic as well as digital readout of power levels.

The system is comprised of two parts:

1.    The power meter head.

2.    The support unit, based on a National Instruments USB-6211 data acquisition module.

Specifications:

• Measures power in free-space beams

• Displays power on a computer

• Fully automatic absolute calibration using electrical film heating under software control

• Frequency dependent window loss correction

• Accuracy better than 10%

• NEP typically 5μW/Hz^?

• For energy measurement the typical NEJ is about 1μJ

• Broad Band: 30GHz to 3THz and beyond

• Sensitive Area greater than 30mm in diameter

The Head

The head is a photo-acoustic detector using a closed air-cell and a pressure transducer.

Calibration is provided by ohmic heating of a thin metal film within the cell.

The Support Unit

The support unit is based around a National Instruments USB-6211 data acquisition module.

Additional electronics have been added to provide film heating for calibration and to amplify

the signal from the head's microphone pressure sensor. The compiled software, written in

LabVIEW, implements a lock-in amplifier and displays the microwave power.
