The TR12 module is a galvanic isolated 16 channel digitizer with onboard memory in a 6U high CompactPCI form factor. The 16 channels are sampled simultaneous with 16 bit resolution. The samples are stored in onboard memory. The memory is organized as a ring buffer. On every sample clock the A to D converters convert the analog inputs and send the samples over the isolation barrier where they are stored into the ring buffer. After the event of a trigger a programmable number of post trigger samples will be stored into this ring buffer before sampling stops. The number of samples from start until trigger is counted in 32 bit counters. The samples in memory can be copied to the PC memory with DMA transfers. In parallel samples are also available through FIFO’s at sub sample rates for control applications. The depth of the FIFO’s is software selectable, up to 16 samples per channel.
Modules may be connected via the front panel trigger- and clock signals or via PXI to increase the number of channels.
The plug and play functionality provides easy setup and use. The module includes software drivers for Linux.
