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.
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.
