GFT1004 | 4-Channel 1 pS Digital Delay Generator Up to 10 Channels Optional [Obsolete]
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 1004’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 1004’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 < 1 ps and channel to channel jitter is less than 15 ps rms. BNC outputs on the rear panel deliver up to 10 V levels into 50 Ω. One Trigger Input channel (T0, 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.
