The compact timing generator TG10 with an ultra-stable 0.2 ppm internal clock creates up to 8 delay channels precisely synchronized to the internal or external clock at up to 100 MHz repetition rate. TG10 features a precise trigger output with an exceptionally low 3-5 ps jitter, which makes it an ideal choice for high-speed acquisition systems like streak camera triggering.

In addition to the standard pulse generator features, TG10 allows to combine up to 4 pulse outputs to signals by OR, AND, NOT logical operations, and instantly switch between two configurations in delay blocks. Burst counter, gate input, frequency divider, or software commands may serve as the configuration switching signal sources. Configuration switch is used to control optical pulse pickers (EOM or AOM) in a highly flexible manner.

The following are the key features of the TG10 module in addition to standard pulse generator:

• Ability to lock to an external clock source, usually photo-diode pulse train. The triggering system is locked to the laser oscillator then, and trigger time is always in phase with the optical pulse.
• Instant switch between two configurations in delay blocks. Burst counter, gate input, frequency divider, or software commands may serve as the configuration switching signal sources. Configuration switch is used to control optical pulse pickers (EOM or AOM) in a highly flexible manner.
• Low jitter sync pulse output is used for high-speed acquisition systems like streak camera triggering. The typical jitter is 3...5 ps to the optical pulse.
• Control connector. The software-controllable multiplexer may divert any of the output signals to this connector to sniff what is on other connectors without disturbing them.
• Clock output: 1:1, 1:2 frequency.
• Up to 4 pulse outputs can be combined to single signals by OR, AND, NOT logical operations.
• DAC output, controlling, e.g. AOM pass though.

TG10 has the following input and output channels:

• OUTx - five digital general-purpose output (4.5V @ 50 Ω)
• AN OUT - analog output with 12-bit resolution (1V @ 50 Ω)
• COM TRIG - common trigger output. Configurable source (2.5V @ 50 Ω)
• PRE TRIG - precise trigger output channel. Configurable source (>1.5V @ 50 Ω)
• GATE IN - configuration switch and burst control input. (LVTTL, tolerates 5V. 0.2 mA pull-down)
• SYNC IN - trigger input for DC to 20 MHz frequencies. (LVTTL, tolerates 5V. 0.2 mA pull-down)
• CLK IN - clock input for 10 MHz to 100 MHz frequencies. (0.5V to 3.3V @ 50 Ω pk-pk, sine or pulses)

The TG10 device has an LCD touch screen for the manual control and a tunable knob for the adjustment of selected values set on the touch screen. Instructions of required actions are always displayed at the bottom of the screen. The timing generator has a digital control interface via CAN bus. Communication protocol with description for CAN is provided on request. CAN to USB converter is also available from EKSMA Optics.
