FUNCTIONAL DESCRIPTION
The 1503- and 1503J-series devices are mechanically variable, passive delay
lines. The signal input (IN) is reproduced at the tap output (TAP), shifted by an
amount which can be adjusted between 0 and T
D
, where T
D
is the device dash
number. The fixed output (OUT) reproduces the input, delayed by T
D
, and
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 / T
R
, where T
R
is the rise time of the line (See Table).
