About This Product
■ Advantages to use TEDS microfones
The TEDS microphone has a cartridge's individual identification information and load sensitivity in TEDS, and the biggest advantage is that when connected to the measuring device, this information is automatically set. The mini CD attached to many TEDS microphones contains individual characteristic data, and can be used to correct frequency characteristics. In addition, cartridge and preamplifier are sealed as a unit in a clean room to avoid incorporation of impurities such as chili, which causes aging of performance.
All TEDS Microhons, excluding TEDS template 4957 and 4958, are provided in a template that meets IEEE 1454.4 V0.9. If you specify it at the time of purchase, you can provide IEEE 1545.4 V1.0 template free of charge.
■ Data transmission
In general, there are two ways to transfer data from TEDS chip to analyzer. The simple method is to use a dedicated line for data transfer called class 2. In the conventional LEMO type TEDS preamplifier, 5 output terminals are transferred to TEDS data.
On the other hand, the method of class 1 is a single -track system such as DeltaTron, and signals and data transfer are performed at the same line. In this case, it is possible to use a single track by changing the mode (TEDS data/signal) electrically.
■ Custom -made TEDS Microphone
You can also provide a custom -made microphone. If you can not find any specifications, please contact us.
■ Free sound field type micro hon
The free sound field microphones are designed to have flat frequency characteristics in the free sound field. High frequency reflections and diffraction increase the pressure of the diaphragm in front of the diaphragm. If this is not corrected, the output voltage from the microphone will increase, so it is optimized so that flat frequency characteristics can be obtained for the incident sound from the 0 ° direction.
Freedom -type micro hons are commonly used in places far away from iconic chambers and reflected structures. It is also used for general electrical sound purposes, such as measurement of loud speakers and microphones.
