The MSD-200 series is a 1U rack-mount modular device. It allows the installation of various modules, such as generators, signal splitters, and meters, in one rack-mount case. 

There are a few predefined configurations. These cover the basic, most common customer requirements.

The MSD-RAA contains a high-precision rubidium oscillator-driven generator of 10MHz and 1PPS reference signals – MSD-295 module. It delivers unmatched signal purity and frequency stability for 10MHz sine wave, 10MHz pulse, and 1PPS. MSD-295 can be disciplined from the internal GNSS receiver to get a more accurate UTC scale. In addition, the device contains a UI panel with LCD, keyboard, and LED signaling, a single power supply 230VAC, and the 12-output TTL splitter MSD-243. Optionally, you can order the second splitter module, e.g., MSD-243 (12xTTL) or MSD-244 (16xRS422), and one MSD-291 – 1PPS delay meter. All this in one 1U metal 19-inch rack case.

The MSD-DAA contains a high-precision rubidium oscillator-driven generator of 10MHz and 1PPS reference signals—the MSD-295 module. It delivers unmatched signal purity and frequency stability for 10MHz sine wave, 10MHz pulse, and 1PPS. The device contains a UI panel with LCD, keyboard, and LED signaling, a single power supply 230VAC, and optionally the MSD-291 – 1PPS delay meter. All this is in one 1U metal desktop case.

The MSD-RAB contains two MSD-243, 12-output TTL splitters, a single 230VAC power supply, and optionally up to two next TTL or RS422 splitter modules. All this is in one 1U metal 19-inch rack case. Splitter modules can have RS422, TTL, or GPS input cards installed.

MSD-RAB – modules with BNC and SMA sockets.

The MSD-RAC contains two MSD-244, 16-output RS422 splitters, a single 230VAC power supply, and optionally up to two next TTL or RS422 splitter modules. All this is in one 1U metal 19-inch rack case. Splitter modules can have RS422, TTL, or GPS input cards installed.

MSD-RAC – one MSD-243 with RS422 OCP card and one MSD-243 with GNSS/GPS OCP card.

The MSD-Antenna GNSS/RS485 is a compatible NTS-3000/4000/5000* GNSS receiver with an RS485 interface. It can be connected to the indicated servers instead of the original NTS-Antenna*. The receiver is equipped with interchangeable OCP-RCB format GNSS cards. The connection is made of a typical UTP/SFTP CAT 5+ cable. The maximum distance is 700m.

MSD-Antenna PCSK-225/RS485 is a receiver of the time frame signal broadcast by the transmitter of the first program of the Polish Radio in Solec Kujawski at 225kHz. The signal can be received throughout Poland and some neighboring countries. The Central Office of Measures provides the time standard with a synchronization accuracy of 10ms. The receiver is equipped with interchangeable OCP-RCB format cards. The connection is made of a typical UTP/SFTP CAT 5+ cable. The maximum distance is 700m with an RS485 interface.

The MSD-Antenna DCF77/RS485 is a time-frame receiver transmitted by the DCF-77.5 transmitter in Mainflingen near Frankfurt (Germany). It covers Western and Central Europe. The receiver is equipped with interchangeable OCP-RCB format cards. The connection is made of a typical UTP/SFTP CAT 5+ cable. The maximum distance is 700m with an RS485 interface.

The new receivers are modular designs. The main interface board is equipped with OCP-RCB (TAP) standard cards, which allows you to create different variants of receivers depending on your needs. All versions use the same tight RJ-45 connector in the IP67 class, which ensures an easy and convenient connection to the time server.
