The GFT1004 is a multi-channel digital delay generator that functions either as a standalone or as a component in a timing system. As a standalone instrument, it will produce multiple channels of delays which can be triggered by an external trigger or by selectable internal triggers. As a component of a timing system, the GFT1004 (with option 1) is operated in conjunction with a GFT3001 master transmitter. The 3001 is the master transmitter that controls a number of 1104’s to provide timing, triggering, gate, delay, and inhibit signals. A serial data stream over optical fiber provides clock synchronization, single shot triggering, repetitive triggering, and inhibit information to the various 1104’s at distances greater than 1 km from the GFT3001 master transmitter.
The GFT1004 rackmount Digital Delay Generator provides four/eight/ten independent delay channels from a single trigger input or internal clock. The delay resolution on all channels is a remarkable < 1ps and channel to channel jitter is less than 15ps rms. BNC outputs on the rear panel deliver up to 10V levels into 50 Ω. One Trigger Input channel (To, zero delay) is used to reference the four output channels in a variety of different operation modes.
The input connector, also on the rear panel, allows you to use an external trigger and still keep trigger jitter to a minimum. Electrical or Optical inputs are accommodated using a variety of operating modes. Delay parameters and operation modes may be programmed using the front panel interface or using remote programming over Ethernet.
