Becker Nachrichtentechnik GmbH
Modern receivers for broadcast have a large number of antenna inputs for the different radio bands. The devices of the FDMX series can be used to supply the antenna inputs with RF signals. The devices of the FDMX series splits a sum signal in frequency division multiplex into the individual broadcast bands and the L1 satellite navigation band (GNSS). Additionally, DC loads are provided for each antenna input to simulate active antennas. The presence of remote power supply is indicated by an LED on the units.

Counters and Timers
-
Orbit Controls counters and timers are designed for connection to practically all industrial sensors and pulse sources . They can be used as process monitors to display the process variable to be measured or as process controllers for control and monitoring tasks. The devices display and process pulses and frequencies, as well as quadrature signals from incremental and absolute encoded rotary encoders. In addition to information on the display, the devices also generate data and analog outputs and monitor preselected limit values. The process parameters are entered via the keyboard so that the display is calibrated in the required units and the output signals, serial interfaces and limit values are optimized.

High Frequency Current Transformers
-
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.
