FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The 2075- and 2075A-series devices are single-input, single-output,
IN
Signal Input (BNC)
passive delay lines. For the 2075, the signal input (IN) is reproduced at the
OUT Signal Output (BNC)
output (OUT), shifted by a time (T
D
) given by the device dash number.
The rise time (T
R
) of the lines is no more than 1ns, resulting in a 3dB
bandwidth of approximately 700MHz. For the 2075A, the delay is mechanically variable from 3ns to 7ns and
the bandwidth is 50-150MHz. The characteristic impedance of both lines is nominally 75 ohms.

Network analyzer is used in phase measurement mode, normalized with a calibrated BNC jumper between
input and output signals. Delay is related to phase lag with proportionality constant of 100ps/deg.
