The GEN7tA is a rack mountable transient recorder and data acquisition system. The standard 1 Gbit Ethernet interface supports streaming recorded data directly to the PC at 100 MByte/s. The optional 1 Gbit optical Ethernet allows for isolated control of the mainframe and for cable lengths up to 10 km mi) while maintaining full streaming performance. For higher streaming rates of 400 MB/s a 10 Gbit electrical or optical Ethernet option is available.

When more reliable or distributed storage of recorded data is required, the GEN7tA supports an optional, removable Solid State Drive or can directly store recorded data on an external Network Attached Storage (NAS) device.

To synchronize the absolute time to other systems, the GEN7tA supports the PTP protocol on both the standard and optional optical 1 Gbit Ethernet interfaces.

Full transparent time and trigger synchronization on multiple GEN DAQ systems can be done using the standard optical Master/Slave synchronization connector. For legacy or industrial systems, the GEN7tA optionally supports IRIG A & B or GPS-based time synchronization.

The GEN7tA is configured and controlled using Perception software purchased separately and runs on a PC provided by the user. This combination results in a sophisticated instrument for ultra-fast recording, analysis and reporting.

Acquisition System

System Time Base and Synchronization

Central time base for all acquisition cards


± 3.5 ppm; aging after 10 years ± 10 ppm


Binary, Decimal or External

Synchronization sources

IEEE1588:2008 PTP V2 (Precision Time Protocol) using Two-Step master, End-to-End protocol

Master/Slave synchronization; Slave or Master mode on built-in connector Master output card (G083): Option to synchronize up to 48 Slave systems IRIG (G001/G002): Option to synchronize IRIG A & B time sources

GPS (G002): Option to synchronize GPS satellite time

PTP synchronization accuracy

± 150 ns; with one PTP compatible Ethernet switch used

Use only End-to-End Two-Step master PTP aware switches

Acquisition Slots

Unused slots must be covered using the GEN DAQ blind panel. This closes the mainframe front panels for EMC/EMI and safety compliance and also regulates the internal airflow to cool the acquisition system correctly.

Number of slots


Acquisition cards

Any combination of GEN DAQ acquisition cards supported

Digital Event/Timer/Counter connector

3; Connected to slots A and B, C and D, E and F

Thermal control

Every acquisition card and the acquisition system monitors its own temperature and status. This is used to regulate fan speeds and reduce noise while optimizing airflow and power consumption.


Any changes to the acquisition system configuration may change its internal thermal gradients. As accurate calibration relies on a steady and repeatable thermal environment, calibration is void if changes are made in the configuration. For information on calibration impact, please refer to the individual card specifications.
