GFT1208/1218 Digital Delay Generator

GFT1208/1218 8 Channel Digital Delay Generator

Summary

Greenfield Technology's GFT1208/1218 Digital Delay Generator provides eight completely independent delay channels. The timing resolution on all channels is <1 ps and channel to channel jitter is less than 15ps. LEMO outputs deliver 2.15V (model GFT1218), 2.5V (model 1208) to 10 V level info 50 Ω .

One T0 sync output channel is provided (zero delay) to reference all eight output channel in different operation modes. Additionally, one input channel is used to trigger off all output channels. In system mode, the module may be optical triggered by GFT3001 via an optical network.
