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.

Passive probe with X1/X10 switch
-
They are normally designated X1 and X10, although 1X and 10X are sometimes seen. The designation refers to the factor by which the impedance of the scope itelf is multiplied by the probe.The X1 probes are suitable for many low frequency applications. They offer the same input impedance of the oscilloscope which is normally 1 MΩ. However for applications where better accuracy is needed and as frequencies start to rise, other test probes are needed.

Boxcar Averager
-
The Zurich Instruments Boxcar Averager operates as a high-speed digitizer synchronized to a reference oscillator that is phase-locked to the periodicity of the experiment. In the case of the laser repetition rate, for example, every data sample recorded at the input can be associated with the phase of the experiment and the signal components not synchronized with the experiment are strongly suppressed. The implementation based on an external reference signal removes the trigger jitter, and the digital realization enables a dead-time-free operation.

16 Bit DDS Generator Up To 200 MHz
96xx series
-
The 96xx series DDS generators deliver the highest performance in both speed and resolution. The series includes produts between one and 24 synchronous channels. DDS – Direct Digital Synthesis – is a method for generating sine waves from a single, fixed-frequency reference clock and is widely used in signal generation applications. The DDS functionality implemented on Spectrum Instrumentation’s AWG platform is based on the principle of adding multiple “DDS cores” to generate a mul?ti-carrier (multi-tone) signal, with each carrier having its own well-defined frequency, amplitude and phase. In addition to these static parameters, there are also build in dynamic parameters like frequency slope and amplitude slope to allow for intrinsic linear changes for multiple cores.
