Term Definition
DBS

Enable accurate pulse detection.

SP Devices’ proprietary technology for baseline stabilization, DBS, tracks and compensates for baseline variations to suppress, for example, temperature drift in the detector. This enables accurate triggering even on small pulses and eliminates interleaving pattern noise, which can be particularly important when averaging many acquisitions. The precision of DBS is as high as 22 bits.

DC-coupled

Means that the frontend of the digitizer will allow both DC and AC components of signals through.

Decimation

Decimation is a two-step sample rate reduction method where the data is first filtered, then samples are discarded.  The filter operation reduces the bandwidth and increase the SNR. For high order decimation, the SNR is very high and the data word has to be increased from 16 bits to 32 bits so that the quantization noise does not limit SNR. The sample skip operation reduce the data rate by discarding samples. (Notice the difference to sample skip, where samples are discarded without filtering.)

Digital Down Converter

A DDC combines a complex mixer with a decimation filter to select a specific RF band and reduce the data rate to suit the bandwidth of that RF band.
