1503C TDR


Tektronix - 1503C
Range: 0 to 2000 feet
Resolution: 0.12 in
Channels: 1

The 1503C provides high-energy, 1/2 sine-shaped pulses for long cables. Range of the 1503B, dependent upon cable type, is up to 50,000 feet. Resolution capability provides for resolving faults as close together as one foot on short cables. Impedance levels of 50, 75, 93, and 125 ohms are selectable.
