GPS NTP Time Server - SYNTIME
-
Signals & Systems India Private Limited
Your product description goes hGPS NTP Time Server (SYNTIME) for Network Time Synchronization is a highly accurate time server. It generates time protocols to synchronize NTP/SNTP clients (Simple Network Time Protocol)/PTP clients (Precision time protocol IEEE 1588) over the network and operates at a speed of 10/100/1000Mbps. The NTP server accepts the time and frequency signals from sources like GPS or GLONASS. It achieves nanosecond accuracy and the system clock operates at stratum 1 when synchronized with time sources. It is a sleek, rack-mountable unit that synchronizes and maintains equipment/device time and avoiding any time drifts due to local RTCs. NTP output from time server supports unicast, broadcast, and multicast methods based on selection and behaves like a reference clock for the network. Apart from time synchronization protocols, it supports MD5 (Security key), SNMP, SSH, HTTP (Configuration), TELNET, FTP, and SYSLOG. IP address of the LAN ports can be field configurable.

DC - 400 MHz PC-Based Timer Interval Analyzer
-
GuideTech’s GT658PCI is an ultra-fast, high resolution, DC – 400 MHz Time Interval Analyzer (TIA), ideal for most PC-based lab bench (timing) test applications. What makes the GT 658 superior to traditional counters is analogous to the difference between volt meters & digital scopes. While both measure voltage, the scope provides much more information about the dynamics of the signal. This is because our patented TIA substantially increases measurement speed, and the measurements are displayed as afunction of time. All of these features, along with the benefit of ‘continuous time correlation to a common reference between all measurement time stamps,’ enable our TIAs to make measurements that weren’t previously possible with traditional counters.
