Masterclock

For over 30 years, Masterclock has been trusted worldwide to provide mission-critical timing systems. From helping keep NASA launch operations precisely in time to synchronizing broadcast studios for seamless transitions, Masterclock's in-house engineering, manufacturing, and research, located in St. Louis, Missouri, ensures its systems are built to fit each application.

Network Time Distribution Solutions

Masterclock's timing solutions include highly precise time code generators and readers, such as master clocks and NTP (Network Time Protocol) servers designed for broadcast, enterprise, and mission-critical applications. The NTP100 family of NTP servers can distribute legally traceable time across local area networks (LANs) and enterprise networks while supporting the official industry standards for network time protocols, such as NTPv2 (RFC 1119), NTPv3 (RFC 1306), and NTPv4 (RFC 5905). For advanced synchronization requirements, the GMR1000 and GMR5000 Masterclocks combine NTP server functionality with PTP grandmaster, time code generator, and frequency reference capabilities. They can be paired with highly accurate time sources, such as GPS satellites and GNSS satellite systems, to achieve exceptional timing accuracy.

Synchronized Digital Clock Systems

Masterclock also offers a complete range of countdown timers and digital display clocks for professional facilities. These synchronized digital clocks can reference a master clock, an NTP server, or a timecode source to provide accurate time displays throughout a building or campus. By referencing time from a centralized and highly accurate source, they help eliminate drift between clocks and ensure dependable timekeeping. They are available in a variety of sizes, colors, mounting configurations, and can even be customized to fit the needs of specific broadcast studios, control rooms, educational institutions, healthcare facilities, and corporate environments.

FAQs

What timing protocols does Masterclock support?

Depending on the product, Masterclock systems support network time protocols for IP-based synchronization such as NTP and SNTP, Precision Time Protocol (PTP, IEEE 1588), IRIG-B (a widely used timing standard in aerospace, defense, and industrial systems), SMPTE time code used in film, television, and broadcast production workflows, and EBU time code standards used in European broadcasting environments.

Do Masterclock products require GPS?

Masterclock products do not always need GPS. Many systems use GPS or GNSS for very accurate timing, but it's not required for every use. Depending on the model, Masterclock products can also sync to network time sources like NTP, Precision Time Protocol (PTP), or other external timing signals. This flexibility lets them work well with both GPS and network-based timing setups.

Can Masterclock synchronize analog and digital clocks?

Yes, Masterclock systems can synchronize both analog and digital clocks throughout a facility, depending on how they are set up. They send accurate time to networked clocks, digital displays, and other devices, so time stays consistent everywhere.
