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. ![Model 594](https://www.berkeleynucleonics.com/wp-content/uploads/uploads/594-1.jpg) --- _In regards to limited quantity, please contact BNC about current stock and our recommended replacement model._ ##### [Features](#features-section) ##### [Specifications](#specifications-section) ##### [Options](#options-section) ##### [Tech Resources](#technical-resources-section) ##### [Downloable Resources](#downloadable-section) ##### [Price List](#pricelist-section) #### Overview ##### Features - Four / Eight / Ten Independent Delay Channels - < 1 ps delay resolution - < 15 ps rms jitter - Maximum Delay of 10 Seconds - Rack 19″, 1U - Scaleable to 100’s of Channels - Remote or Local Programming Options ##### Service Advantage - Components Test - ATE Application - Laser Timing Application - Precision Pulse Application - Synchronous Multi-channel - Triggering #### Specifications ##### Delay **Channels** 4 independant (8/10 opt.) **Range** 0 to 10 seconds **Resolution** 1 ps **RMS Jitter** < 10 ps + delay x 10-7 **Accuracy** < 150 ps + delay x 10-7 **Trigger Delay** < 100 ns (insertion delay) **Time Base** 0.5 ppm ##### External Trigger Input **Repetition Rate** Up to 1 MHz **Trigger Level** +1 V/ 50 Ω **Slope** Positive **Connector** BNC ##### Internal Trigger **Two Generators** Frequency = 1 Hz to 1 MHz in step of 1 Hz ##### Output Pulse T1 to T4 **Amplitude** 2.5 V to 10 V in step of 10 mV **Load** 50 Ω **Rise/Fall Time** 1 ns / 3 ns **Width** 100 ns to 10 ms in step of 6.43 ns **Connector** BNC ##### External Time Reference **Frequency** 10 MHz (other frequency are available up to 80 MHz) ##### Inhibition Input **Inhibition Input** Trigger level = 1 V, repetition rate < 1 kHz ##### General **Software** Free drivers for seven **User Interface** Front panel, Ethernet 10/100 Mb/s, Internet (Web page) **Power Consumption** 90 To 240 V / 50 – 60 Hz/ 0.25 A **Weight** < 5 kg **Size** 19″ W X 363 mm D X 1U H **Shipping Dimensions** 24 x 19 x 13″ **Shipping Weight** 33 lbs #### Options **Option 1** Extension to 8 channels **Option 2** Optical input for timing system mode **Option 3** Clock output **Option 4** 32 V channel output (W=1 µs, rise/ fall time = 2/10 ns under 50 Ω) **Option 5** Extension to 10 channels **Option 6** 5 V to 20 V channel output (W=0.1 to 10 µs, rise/ fall time <5 ns under 50 Ω) **Option 7** TTL level (2.5 to 6 V) channel output (positive or negative pulse) **Option 8** Optical channel output #### Technical Resources [ Model GFT1004 Datasheet](https://www.berkeleynucleonics.com/download/20674/?tmstv=1778700935)#### Downloadable Resources Downloadable resources such as datasheets, firmware, software, drivers and products manuals.
