The four models in the OE-DD-A digital delay generator series feature low-jitter adjustable delays in the range of 30 ns to 1 µs (Model OE-DD-A4-PS), 30 ns to 9.999 µs (Model OE-DD-A1-PS), 100 ns to 999.999 µs (Model OE-DD-A2-PS) and 100 ns to 5.0 µs (Model OE-DD-A3-PS). All models are available in single or dual output channel versions. Dual output units feature two independent delay controls.

To specify the two output channel option, add the suffix -TC to the model number.
Click here for a description of the OP1B features.
See below for a description of -OP1 option. To specify this GPIB option, add the suffix -OP1 to the model number.
Valid for single-channel model only.
To specify the 0.1 ns resolution option, add the suffix -HR to the model number.

-OP1 OPTION
The -OP1 option is a low-cost limited feature IEEE-488 GPIB interface which provides the following features: SH0, AH1, T0, TE0, L2, LE0, SR0, RL0, PP0, DC2, DT0, C0 (Bus listener only).

The -OP1 option places an interface card in the pulser which provides 8-bit control of amplitude, pulse width, pulse repetition frequency and delay when the rear-panel LOCAL-REMOTE switch is in the REMOTE position and a GPIB cable connects to a PC with an IEEE-488 controller board. The output pulse waveform characteristics are remotely controllable using the mnemonics V, W, R, D or A which respectively represent pulse amplitude (Volts), pulse width (µs), repetition rate (Hertz), delay from sync (µs) or advance before sync (µs). Integer numbers are used (instead of exponential notation). To specify this option, add the suffix -OP1 to the model number. Note that the -OP1 option includes the GPIB cable.
