R&S OSP-B114 current consumption
The R&S OSP is able to supply a nominal current of 800 mA for the module
R&S OSP-B114. But the total current for all three slots in the R&S OSP is limited to 2 A.
8.7 Application of Module R&S OSP-B158
8.7.1 Controlling active antennas with R&S OSP-B158
The module R&S OSP-B158 has 16 differential RS422 output lines and four
independent DC-voltages.
Since RS422 is a symmetric signal transmission and is therefore very robust against
incoming electromagnetic interference, this module features an appropriate interface
to control and supply devices in harsh environment with large cable lengths.
Active monitoring and direction finding antennas fulfill this condition and are the
preferred application for the R&S OSP-B158. The additional power supply port with
different voltages supersedes an external power supply.
