Directional Acoustic Transponder (DAT)
-
The Benthos Directional Acoustic Transponder (DAT) is anextension to the Teledyne Benthos ATM-900 Series modem, which automatically estimates the azimuthal and vertical arrival angles of a message sent by a remote modem. The system is a modified ultra-short baseline (USBL) which uses a broadband component of a typical modem message to form estimates of arrival angle(s). While conventional USBL devices employ tonal signals, our appropriate processing of wide band signals provides far better combined range and arrival angle estimation, especially at low Signal to Noise Ratio (SNR). Our device offers a clear 360 degree field of view in azimuth, and an approximate vertical coverage spanning + 90º overhead to -50º below horizontal.

Noise Figure Measurements With Vector Correction
S96029B
-
This software application enables high-accuracy noise figure and noise-power measurements of amplifiers. It utilizes Keysight’s unique vector-source-correction technique, which uses a source-impedance tuner to remove the effects of imperfect system-source match. This approach yields accuracy that surpasses that provided by the Y-factor method and other cold-source implementations, especially for in-fixture, on-wafer, and automated-test environments. A scalar-calibrated method is also available that offers less accuracy but is faster and does not require an impedance tuner.

CAT-5 Video Receivers
-
Analog Devices high speed, differential CAT-5 video receivers and equalizers compensate for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths. Our video receivers provide excellent common-mode rejection that enables the use of low cost, unshielded twisted pair cables in noisy environments.
