Manuals – Specifications – Links – Pictures

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.
• System Risetime - 10% to 90%, 200 ps (1.15 in./2.92 cm).
• 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.
