RM8X4 Quad Software Defined Modem & ALE – 3, 6 kHz
The RM8X4 Quad Software Defined Modem is a purpose-built stand-alone hardware platform housing four independent modem and ALE controller functions.
The RM8X4 unit has high commonality with the RM8 and is intended for strategic and maritime data communications where size, weight, power and cost are at a premium.
The RM8X4 can be installed as both land and ship-borne 19-inch rack equipment occupying only a single 1U slot.
The RM8X4 offers the same wide range of standards-based waveforms and protocols found in the RM8. These are suitable for interoperable link setup operations and data transfer, whether point-to-point or point-to-multipoint.
The RM8X4 is capable of four-channel receive diversity processing, offering a significant performance gain and making the RM8X4 ideal for naval and maritime shore station deployment.
The function of the RM8X4 is determined by the selection of one of the following software packs:
- M1: LF and HF Modem (SSB, ISB, Up to 19200 bps)
- M2: HF Modem (SSB, up to 9600 bps)
The following ALE software options are available for use with M1 and M2:
- 2G ALE Controller Software Option
- 3G ALE Controller Software Option
The following software options are available in addition to M1 and M2:
- V/UHF Data Modem (up to 128000 bps)
