Q.series - Synchronous Measurement and Conditioning

Synchronized capture of all measured values is essential, particularly for highly dynamic measuring assignments with measuring rates in the high kHz range, to allow correlated evaluation of multiple axis acceleration rates. With the Q.series all measuring modules and slide-in units are queried synchronously by the test controller to minimize jitter to <5 µs within a system.

Based on the IRIG Standard (Inter Range Instrumentation Group) it is possible to precisely synchronize a number of measuring systems depending on the requirements of the application. A standard RS485 interface is used, allowing large distances between controllers.


Method A
Controller 1 is the master and synchronizes controllers 2, 3, and 4, which are configured as slaves.

Method B
A time signal receiver synchronizes all controllers connected.

Method C
The master controller receives the GPS signal over the RS232 interface and transfers it to all slaves via the RS485 interface. Moreover it is possible to capture the GPS position data and link it to the measuring signals.

Method D
All controllers receive the time signal as SNTP via the Ethernet interface.
