FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The 3D2700 device is a single-input, single-output, passive delay line.

The signal input (IN) is reproduced at the output (OUT), shifted by a time

(T_D) which can be adjusted via seven binary-weighted switches. The

value of these switches, multiplied by the device dash number,

Signal Input (BNC)

OUT Signal Output (BNC)

determines the device delay (referenced to the delay with all the switches off). The device is offered in 50-

ohm and 75-ohm impedance versions.
