FUNCTIONAL DESCRIPTION
The 2075- and 2075A-series devices are single-input, single-output,
passive delay lines. For the 2075, the signal input (IN) is reproduced at the
output (OUT), shifted by a time (TD) given by the device dash number.
The rise time (TR) of the lines is no more than 1ns, resulting in a 3dB
bandwidth of at least 350MHz. For the 2075A, the delay is mechanically variable from 3ns to 7ns and the
bandwidth is 6MHz. The characteristic impedance of both lines is nominally 75 ohms.

TEST CONDITIONS
INPUT: OUTPUT:
Ambient Temperature: 25oC ± 3oC Z
Source Amplitude: 0dBm typical
Source Impedance: 75Ω nominal
Input Frequency: 27.777778MHz
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.
NOTE: The above conditions are for test only and do not in any way restrict the operation of the device.
