THE PULSE OF THE FUTURE PDG-2510 Tw o C h a n n e l D i g i t a l D e l a y Pulse Generator The PDG-2510 is a precision digital delay and pulse generator providing two output channels, each with independently adjustable delay and pulse width, plus a Sync (T0) output. The accuracy, precision and flexibility of the PDG-2510 makes it well suited for use in laser timing, automated testing and precision pulse applications. The PDG-2510’s Sync (T0) output marks the beginning of a timing cycle, and is generated by the internal rate generator or in response to an external trigger. The delay and pulse width of the two outputs can be set from 0 to 99.9S relative to the T0 trigger with 25 ns resolution on its highest precision range. The PDG-2510 can be triggered internally from 1 Hz to 100 KHz with three-digit frequency resolution. External, single-shot (front panel push-button) and burst mode triggers are also supported. In external trigger mode, the maximum trigger frequency is 5MHz. Operating modes include continuous (pulse generator), pulse count, divide-by-N, burst and counted burst, providing flexible control of the pulse outputs. The output pulse waveforms may be inverted in all operating modes. Pulse widths can be specified as a time period, or set based on a duty cycle (ratio of pulse “on” time to “off” time) for a given frequency. The PDG-2510 may be operated through its intuitive front panel controls. For automated applications, complete control of the generator is provided through the standard RS232 computer interface. Up to five system configurations may be stored in internal non-volatile memory, providing instant recall of frequently-used configurations. • Sync (T0) Plus Two Independent, Digitally Controlled Outputs • 0 to 99.9S Delay and Pulse Width Ranges With 25ns Resolution • 100KHz Maximum Frequency (Internal Trigger), 5MHz (External Trigger) • Standard RS-232 Computer Interface • Store & Recall Up To 5 System Configurations • Continuous, Single-Shot, External Trigger, Burst, Counted Burst, Pulse Count And Divide-By-N Modes The PDG-2510’s versatility, ease of use and Sync (T0) plus two independent outputs make it well suited for a wide variety of test and measurement tasks. It is also ideal for laser timing applications, in which the Sync (T0) output is used to trigger the pulsed laser and set the system’s repetition frequency. Delayed output 1 controls the laser Q-Switch, and output 2 can be used to synchronize other elements in the system, such as a detector or data acquisition hardware. Operating Modes: Generates pulses at the rate set by the internal frequency generator, or by an external trigger Pulse Count Mode Outputs pulses at the rate set by the internal frequency generator or external trigger and stops after N pulses Channel 1 operates in continuous Divide By N mode, channel 2 pulses every Nth (Output-2 Mode) pulse on channel 1 Generates a burst of pulses, repeatBurst Mode ing at a set interval.
