Meinberg Announces Two New Railmounted Reference Clocks

Comprising the GPS183/DAHS, the GPS183/DHS, the GNS183/DAHS, and the GNS183/DHS, each of these models features Meinberg's industry-leading GNSS receiver and reference clock technology for reliable nanosecond-level accuracy and excellent holdover performance. The GPS183 and GNS183 railmounted clocks are the successors to Meinberg's trusted GPS165 and GNS165 clocks respectively, incorporating all of the technological advancements introduced in Meinberg's latest reference clock technology, as well as enhanced surge protection in accordance with IEC 61000-4-5 Level 4.

Meinberg's railmounted reference clocks provide maximum performance in a small package—nanosecond-level accuracy and a wealth of signal outputs in a compact housing measuring just 105 mm x 125.5 mm x 104 mm (4.13 in x 4.94 in x 4.09 in) for the DAHS model, which supports both mains AC power sources as well as a variety of DC power sources, or just 105 mm x 85 mm x 104 mm (4.13 in x 3.35 in x 4.09 in) for the DHS model, which allows the device to be powered by a low-voltage DC power source such as a railmounted DC power supply module or a battery.

The GNS183/DAHS and GNS183/DHS are full 72-channel multi-GNSS solutions with support for GPS L1 C/A code, Galileo E1‑B/C, BeiDou B1I, and GLONASS L1OF reception for optimum GNSS synchronization performance, while the GPS183/DAHS and GPS183/DHS are highly capable entry-level solutions with GPS L1 C/A reception support and integrated frequency downconversion technology that allows the antenna to be connected via long transmission routes of up to 300 m using standard RG58 coaxial cable or as far as 1100 m with H2010 Ultraflex cable.

For such a small device, these railmounted devices support an impressive range of output signals. These include time string output via RS‑232 and RS‑485 signaling, IRIG and IEEE timecode output as amplitude-modulated, pulse-width modulated TTL (DC level shift), and RS‑422 signals, and a large selection of programmable signals such as clock status, pulse-per-second, and a frequency synthesizer that supports frequencies up to 10 MHz.

The GPS183 und GNS183 railmounted systems are configurable via a serial connection using the free Meinberg Device Manager software, which provides comprehensive management options for GNSS reception and signal output, as well as a variety of monitoring options to optimize GNSS reception and clock performance.
