The Tektronix 1503 is a sinusoidal TDR cable tester with a similar design to the 1502B/C step-pulse TDRs.
The 1503 transmits a 5 V half-sine pulse of selectable duration, allowing an operator to examine up to 50,000 feet of cable.
The 1503B and 1503C successors are microporocessor-based.
Key Specifications
- please add
- Test Signal - Step rise.
- Amplitude - 300 mV nominal into 50 Ω load.

- Output Impedance - 50 Ω.
- Electrostatic Discharge Protection - 1 kV/500 pF/1 kΩ.
- Maximum Range - 2,000 ft. (625 m).
- Distance Readout Resolution - 0.05 in. (0.12 cm).
- Noise Filtering - 1 to 128 averages.
- Vertical Scale - 0.5 mp/div to 500 mp/div.
- Vertical Accuracy - ±3% full scale.
- Distance/Division - 0.1 ft./div to 200 ft./div (0.025 m/div to 50 m/div).
- Horizontal Accuracy - 1.6 inches (0.041 m) or ±1% of measured distance plus uncertainty in Vp, whichever is greater (for Vp = 0.66 and Dist/Div = 1 ft.)
When testing 50 Ω cable with a Vp of 0.66, the 1502C allows the determination of 0.5 Ω cable faults. Multiple faults can be measured as close as 0.8 inch. The 1502C measures 50 Ω impedance.
