The signal input (IN) is reproduced at the tap output (TAP), shifted by an TAP Variable Output amount which can be adjusted between 0 and TD, where TD is the device dash OUT Fixed Output number. The fixed output (OUT) reproduces the input, delayed by TD, and GND Ground must be terminated to match the characteristic impedance of the line, which is given by the letter code that follows the dash number (See Table). The tap output is unbuffered. The 3dB bandwidth of the line is given by 0.35 / TR, where TR is the rise time of the line (See Table).
