New calorie-meter type power meter achieves unprecedented levels of measurement accuracy
TOKYO, Japan – May 14, 2014 – Leading semiconductor test equipment supplier Advantest Corporation (TSE: 6857, NYSE: 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 ±11% accuracy.(*1)
TAS5500 & PC Usage Layout
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 others.
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.
- 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.
