二手， Bruel & Kjaer 4602B Telephone Test Head
二手仪器！仪器！仪器！
TheBruel + Kjaer 4602BTelephone Test Head allows accurate and repeatable positioning and subsequent measurement of a telephone handset in the standardized LRGP, HATS and AEN positions as recommended by the ITU-T, as well as in the REF position (OREM A). It is used as a general test jig with other Brüel & Kj?r measurement equipment. The 4602B has been designed to accommodate handsets with antennas.
Features and Benefits:
Measurements in standardised speaking positions: LRGP, HATS, and AEN (ITU-T) and REF (OREM A)
Accommodates IEC318, NBS9A and ITU-T P.51 Type
3.2 Artificial Ears
Optimised acoustic design to minimise diffraction and reflection
Artificial Ears and Ear Simulators
Ear Simulator Type 4157
Ear Simulator Type 4157 is primarily intended for frequency response, sensitivity and distortion measurements on earphones coupled to the ear by ear inserts such as tubes, ear moulds or eartips, for example, as used in hearing aids and operator headsets.
The Ear Simulator consists of a main housing into which are assembled a number of rings whose shapes form annular air volumes connected to the main volume of the housing by air passages. The main ear canal volume is of a similar shape and volume to that of the actual human ear and provides similar acoustic impedance to the insert earphone being tested.
