Model 6040
TTL/ECL Pulse & Delay Generator
Specifications

Operating Capabilities

Single Pulse

Conventional pulse generator operation with selections for rate, amplitude, width and delay.

Double Pulse

Pair of identical single pulses with leading edges separated by a selected delay.

Digital Delay

Selectable duration between an external trigger or mainframe Trig(sync) output and the pulse outputs of the mainframe or a module.

Single Impulse

Subnanosecond fixed width optical "spikes" with selections for rate and delay.

Double Impulse

Pair of identical optical impulses separated by a selected delay.

External Drive

Pulse output corresponds to rate and timing of an external input pulse train, sine waves, etc. Also can allow operation at rates well above 100 MHz.

External Modulation

Analog or digital signals are converted into their optical equivalents. The input modulates light from a selectable quiescent level.

CW

An adjustable steady-state power level of light.

Timing

Internal Trigger

0.01 Hz to 100 MHz.
Accuracy: 0.01% of setting.

External Trigger

Trig In: 0 to 100 MHz.
Threshold Range: +/- 2.5 V.
Threshold Resolution: 10 mV.
Slope: Selectable positive or negative edge.
Sensitivity: 100 mV peak-to-peak for widths >1 ns; 200 mV for 500 ps width.
Input Impedance: 50 ohms.

Pulse Width

3ns to 640s.
Resolution: lns or 5 digits, whichever is greater.
Jitter: 25ps rms or 0.005% x width, whichever is greater.
Accuracy: Up to 9ns- +/ lns; lOns or more- +/ 500ps or 0.2% x width, whichever is greater.

Delay

Variable: 0 ns to 640 s. Fixed(typical): Trig In to Trig Out 20 ns; Trig Out or ECL out 30 ns.
Resolution: 1 ns or 5 digits, whichever is greater.
Jitter: 25ps rms or 0.005% x delay, whichever is greater.
Accuracy: 500 ps or 0.2% x delay, whichever is greater.

Outputs

Trig Out

A time-zero sync pulse at the start of each internal operating cycle.
Amplitude: 2 V into 50 Ohms.
Transition Times: 3 ns rise time, 3 ns fall time.
Width: 3 ns.
Trigger Delay: 20 ns typical(fixed) Trig In to Trig Out. Jitter: 25 ps rms.

Pulse Out

Mainframe front panel TTL-compatible output controllable through the full ranges of repetition rate, pulse width, delay or double pulse timing.
Amplitude: 5 V into 50 Ohms.
Transition Times: 1 ns rise time, 1.5 ns fall time.
Insertion Delay: 50 ns typical(fixed) Trig In to Pulse Out. Jitter: 30 ps rms.

ECL Out

Mainframe rear panel ECL-compatible output coincident with and controlled as for Pulse Out.
Amplitude: -0.8 V to -1.8 V into 50 Ohms.
Transition Times: 700 ps rise time, 700 ps fall time.
Insertion Delay: 50 ns typical(fixed) Trig In to ECL Out. Jitter: 30 ps rms.
