Advantest Launches TAS5500 Terahertz Power Meter


Leading semiconductor test equipment supplier Advantest Corporation
(TSE:6857)(ATE) announced today that a new terahertz power meter,
the TAS5500 is available for purchase.

The TAS5500 is a basic measurement instrument that computes the strength
of terahertz waves by detecting the heat generated when these waves are
absorbed by matter. This enables input power to be measured to ±8%

The unprecedented measurement accuracy of the TAS5500 is based on the
Japanese national standard for infrared power measurement*2,
recalibrated for the terahertz region with measurement data accumulated
by Advantest during the company’s years of developing terahertz analysis
equipment. With national and international standards for terahertz
wavelengths and energies yet to be established, researchers and
developers in the terahertz arena have had difficulty ascertaining the
reliability and accuracy of measured values. Advantest’s new power meter
provides a solution to this challenge. Featuring the robust performance
and cutting-edge functionality that Advantest is known for, the TAS5500
will be an indispensable asset to R&D professionals in the fields of
high-performance terahertz sources, terahertz communications, and many

The TAS5500 will ship in June 2014 at a projected price of 1.8 million.

*1 The measurement accuracy of the TAS5500 has been
calculated with reference to an in-house terahertz power standard
developed by Advantest on the basis of the NMIJ national standard for
infrared waves (see below).

*2 The National Metrology Institute of Japan (NMIJ), a part
of the National Institute of Advanced Science and Technology (AIST),
maintains an infrared power standard of 10.6um.

Product Features

  • A New Terahertz Standard Based on Infrared Power Standard,
    Developed by Advantest

The TAS5500 has been calibrated with reference to the AIST national
power standard for infrared waves of 10.6um. Advantest has expanded the
measurement range of this standard to the terahertz region by
calculating the difference in heat generated when terahertz waves vs.
infrared waves are absorbed. This precise calibration enables the
TAS5500 to deliver highly accurate power measurement.

  • Highly Accurate Heat Measurement

The amount of heat absorbed by a calorimeter varies depending on the
type of electromagnetic wave absorber used and the wavelength of the
input waves, potentially creating measurement uncertainty. The TAS5500
utilizes an absorber with a steady absorption ratio, and relies on
abundant absorption data for each specific wavelength accumulated by
Advantest during the company’s terahertz analysis system R&D activities,
improving measurement stability and accuracy.

  • Desktop Form Factor, Easy PC Connection

The TAS5500 boasts a portable, compact form factor (115mm W x 67mm D x
79mm H) and weighs just 900 grams. It connects to the user’s PC via USB
port for ease of usability.

  • Calibration Service Ensures Continuous Accuracy

Advantest offers TAS5500 users a semiannual calibration service
(separate fees apply) to ensure continuous measurement accuracy .
