Photometric Radiometric Transmitters
HD2021T6 / HD2021T7
-
The transmitters allow converting the photometric quantity “equivalent veiling luminance” – HD2021T7 – or a photometric quantity Luminance (cd/m2) – HD2021T6 – into a current (4…20 mA) or a voltage (0…10 V) signal according to the version chosen. If the acquisition station is far from the probe (>50m), it is necessary to use the current output version.The probe is used for the control of street lighting, in particular, the measurement of equivalent veiling luminance is essential to determine the threshold luminance at the entrance of the tunnels (UNI 11095:2011).

COM-HPC Server Type Size E Reference Development Platform based on Ampere® Altra® SoC
Ampere Altra Developer Platform
Software Development Kit
Backed by a broad Arm® ecosystem with an Ampere® Altra® SoC at its core, using the Arm® Neoverse™ N1 platform, the Ampere Altra Developer Platform provides premium performance from a cloud-to-edge infrastructure, keeps an extremely low thermal envelope, lower TCO, and significantly lower power consumption than x86 designs. It supports the open source EDKII as bootloader with UEFI, so customers can just download a stock AArch64 (arm64) ISO such as Ubuntu and install it through booting a live ISO directly on the target. The same convenience we have become used to by using x86 / amd64 target systems.

Transmitter (Export Only)
SMDB
-
The input section features the unique servo bias input circuitry with a standard TA5M type jack for use with electret lavaliere mics, dynamic mics, or line level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30 dB for excellent overload protection and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio distortion low while preserving short term dynamics.
