Technology

Introduction

The GRAS 90CA-S2 Microphone Calibration System provides for automated and reliable level and frequency response calibration of measurement microphones. The implemented calibration methods conform with these standards:

  • IEC Standard 61094
  • ANSI S1.10 – 1966 (R1976)
  • IEC Standard 60942
  • TEDS Standard IEEE 1451.4

The 90CA-S2 is based on National Instruments\' PXI architecture: NI PXIe-8101 Embedded Controller, including: National Instruments PXIe1071 4-Slot 3U PXI Express Chassis and PXI cards for Control and Data Acquisition.

Features
