M3SR Series 4100
Beside the traditional classes of emission used in HF radiocommunications (A1A, J3E and
J2D in the upper and lower sidebands, A3E, F3E, F1B, B8E, B7D, R3E and H3E), the fol-
lowing important standards from the "HF house" are integrated and available as software
options:
HF modems STANAG-4285, 4481, 4529 and 5065, 4415, 4539, Annex B,
MIL-STD-188-110B and the ISB modem MIL-STD-188-110B Appendix F automatic link es-
tablishment (ALE), 2
ment (ALE), 3
from STANAG-4538
This series provides an EPM (ECCM) method for secure and jam-resistant voice and data
links. With the exception of the independent sidetone emissions B8E, B7D,
MIL-STD-188-110B Appendix F and the navy modem standards STANAG-4481 and
STANAG-5065, it is fully interoperable with the Rohde & Schwarz family R&S M3TR.
Important equipment functions such as automatic link establishment (ALE) or several
HF modems are implemented purely in software.
The radios support frequency hopping and provide interoperability with the
R&S M3TR Family.
R&S M3SR Series 4100 offers solutions to all aspects of HF radiocommunications as well
as a uniform interlogistics concept. The transceiver family is primarily designed for use on
board ships, in coastal stations and semi-mobile shelters.
The main features of R&S M3SR Series 4100 are:
•
Unrivaled radio parameters
-
-
-
-
•
GMDSS interface for the integration in naval DSC systems (HW option)
•
